What is the difference between thermoset acrylic resin and thermoplastic acrylic resin

The performance of the paint film is relatively good, if it is a hydroxyl reaction; The film-forming mechanism of light-curing acrylic resin is basically similar to that of thermosetting, which is commonly used in AC paint and PU paint (one of the main body resins of PU paint is a kind of hydroxy acrylic resin), as for thermosetting acrylic acid, it means that the acrylic resin reaction group is C=C, so the cross-linking density is small, depending on the other film-forming reaction group. Thermoplastic acrylic resin refers to the reaction group of the resin film formation is hydroxyl group, that is, the olefin carbon double bond is broken to form a film, thermoplastic, and the thermosetting acrylic resin is currently divided into three categories, carboxyl groups and other groups, not thermocatalytic only, so the crosslinking density is very high, but 5000. Generally speaking, if the thermoplastic has a larger molecular weight, then it is thermoplastic.

As for what you said about hydroxy acrylic resin is thermosetting or thermoplastic, if it is a carbon-carbon double bond reaction, it is thermosetting, thermosetting and light-curing type have a small molecular weight, tens of thousands to hundreds of thousands, and light-curing type, commonly known as PU paint, but his reaction is photocatalytic.

Acrylic resin is a general term for acrylic acid, methacrylic acid and its derivative polymers. Acrylic resin coating is a thermoplastic or thermosetting resin made of acrylic resin obtained by copolymerization with (methyl) acrylate and styrene as the main body.

As the name suggests, thermoplastic means that the resin (plastic) is solid at room temperature, can be melted into a flowable state when heated to a certain temperature, and then cooled to become a solid again. Thermosetting resins, on the other hand, are usually molded at a certain temperature, but once molded, their properties are fixed, and they will not melt into a fluid when heated.

Thermoplastic acrylic resin does not undergo further cross-linking in the film-forming process, so its relative molecular weight is large, has good gloss and color retention, water and chemical resistance, fast drying, convenient construction, easy construction recoating and rework, and good whiteness and positioning of aluminum powder when preparing aluminum powder paint. Thermoplastic acrylic resins are widely used in automobiles, electrical appliances, machinery, construction, and other fields.

Thermosetting acrylic resin refers to a certain functional group in the structure, which is formed by reacting with the functional groups in amino resin, epoxy resin, polyurethane, etc. during paint making, and the thermosetting resin is generally relatively low in molecular weight. Thermosetting acrylic coatings have excellent fullness, gloss, hardness, solvent resistance, weather resistance, no discoloration and no yellowing when baked at high temperatures.

No, polyacrylic acid can be regarded as an acrylic resin, but it is acidic; Acrylic resins include any kind of polymer that reacts with acrylates.

Acrylic resin is just a general term, actually refers to its esters, acrylic resin is actually methyl methacrylate, ethyl ester, butyl ester and other monomers modified by hydroxyl group, carboxyl group and other polymers formed (including solvent-resistant PMMA).

Polyacrylic acid is a polymer of acrylic acid, similar to polyoxymethylene POM of formaldehyde solution, polystyrene PS of styrene, polyacrylamide PAM of acrylamide, etc., they are polymers of single organic solvents without any functional groups.

The vast majority of acrylic resins are insoluble in water because their primary bonds are ester bonds, and the solid resins formed by the hydrophobic ester bonds themselves also have good water resistance (however, PMMA can still be slightly swollen after long-term immersion in water), and hydroxyl modified water-soluble acrylic resins, which are soluble in alkaline aqueous solutions containing sodium hydroxide.

Acrylic resin is a polymer formed by chemical components such as methyl methacrylate, ethyl ester, butyl ester, etc., and then modified by hydroxyl group, carboxyl group, etc.

Polyacrylic acid is a polymer of acrylic acid, it is a bit like polyoxymethylene POM of formaldehyde solution, polystyrene PS of styrene, polyacrylamide PAM and other chemicals, they are polymers of a single organic solvent, but do not have any functional groups.

Thermoplastic resin: It has the properties of softening by heat and hardening by cooling, and there is no chemical reaction, and this property can be maintained no matter how many times the heating and cooling are repeated. All thermoplastic resins have a linear molecular structure.

Thermosetting resins undergo chemical changes when heated, gradually harden and form, and do not soften or dissolve when heated.

The difference between them is whether the change after the resin is heated and then cooled can be restored, the thermoplastic resin can be restored, and the thermoset resin cannot.

Hello, it is a pleasure to serve you and give you the following answers: Thermosetting acrylic is a thermosetting resin, which is composed of thermosetting acrylic resin and filler, which has good mechanical properties and corrosion resistance, and can be used to manufacture various molds, profiles and mold rotten parts. Unsaturated resin is a plastic resin composed of unsaturated resin and additives, which has excellent mechanical properties and corrosion resistance, and can be used to make various plastic parts.

The main difference between thermoset acrylic and unsaturated resin is that thermoset resin can be fixed during heating and cooling, while unsaturated resin cannot. In addition, thermoset acrylics have better corrosion resistance and mechanical properties than unsaturated resins. Causes of the problem:

1.Improper use: Due to the different properties of thermoset acrylic and unsaturated resins, improper use can lead to insufficient product performance.

2.Improper technical operation: Due to the different characteristics of thermosetting acrylic and unsaturated resins, improper technical operation can lead to insufficient product performance.

Acrylic modified polyester resin"with"Modified polyester acrylic resin"Both are polyesters, both of which are dibasic acids or dibasic anhydrides that react with diols and polyols to synthesize hydroxyl-containing polyester resins. The smiling has nothing to do with pure acrylic.

1. Acrylic modified polyester resin, through the introduction of acrylic, should be to improve the curing effect of the coating, so that it is cross-linked in the cross-linking network.

2. Polyester acrylic resin, itself is UV resin, there is no curing problem, and some other properties are improved through modification.

3. The adhesion of pure acrylic resin is relatively good, the flexibility is generally better, and the brittleness is mainly determined by the amount of styrene added to the formula.

4. Acrylic resin and polyester are generally cheaper than polyester, and acrylic is more expensive.

5. Polyester is not hydrophilic, but it needs to be changed by acrylic, but polyester is needed to change the performance, but the hardness is not enough (the exception is that the hardness of cross-linked polyester will be improved a lot.) The first body is polyester, but the resistance to ductility however, correspondingly.

Acrylic modified polyester resin

Modified polyester acrylic resin

There are slight differences between the two, and that's how I understand them; The second acrylic acid is the body, and the forces between the object are weaker, then because of the presence of its carboxylic acids, through hydrogen bonds and polar groups.

Summary. Acrylic resin and epoxy can be used together to form a mixed variety or be modified into epoxy acrylate alone, liquid E-44 and E-51 bisphenol A epichlorohydrin can only be compatible with low molecular weight acrylic resin, high molecular weight crystallization can not be fully dissolved, and the aliphatic amine and aromatic amine of epoxy curing agent are not good solvents for various solid acrylic resins on the market. This is one of the main reasons why 650 and 651 hardeners can only be low-molecular-weight polyamides and not high-yielding.

Acrylic resin and epoxy can be formed into a mixed variety or modified into epoxy acrylate separately, liquid E-44 and E-51 bisphenol A epichlorohydrin can only be compatible with low molecular weight acrylic resin, high molecular weight crystals can not be fully dissolved, in addition to epoxy curing agent aliphatic amine and aromatic amine are not a good solvent for various solid acrylic resins on the market. This is one of the reasons why 650 and 651 curing agents can only be low-molecular-weight polyamides instead of high-grade trouser sails.

Acrylic resin and epoxy can be used together to form a hybrid variety or be modified separately into epoxy acrylate.

Are the three resins thermosetting acrylic resin, amino resin, and epoxy resin mixed together and miscible with each other?

Thermosetting acrylic resin generally has a relatively low molecular weight, with a certain functional group in the molecular structure, and the functional group cross-linking group of the collapsed Hu in the added amino resin, polyurethane, epoxy resin and other components during painting making reacts to form an insoluble and non-meltable network structure.

The three resins of thermosetting acrylic resin, amino resin, and epoxy resin are mixed together, and they are compatible with each other.

Whether hydroxy acrylic resin and epoxy amino resin are miscible with each other.

Hydroxy acrylic resins are miscible with epoxy amino resins.

Some teachers said that hydroxy acrylic resin has a high molecular weight and cannot be miscible with epoxy resin.

It is miscible and miscible.
