Introduction to several rubber fillers, can rubber fillers be used for plastics

Kiss! Hello, happy to answer your <>

Rubber filler can be used in plastics, rubber filler oil, as a typical petroleum-based softener, used in the rubber industry, at home and abroad for a long time. Mainly used in: all kinds of tires, rubber sheets, reclaimed rubber, rubber auto parts, anti-slip mats, etc.

As a typical petroleum-based softener, rubber filler oil has been used in the rubber industry for a long time at home and abroad. It mainly uses its high aromatic hydrocarbon components to improve the processing and use performance of rubber. After the softener is mixed into the raw rubber, it can not only improve the plasticity of the rubber, reduce the viscosity of the rubber and the temperature during mixing, save the power consumption during rolling, improve the dispersion and mixing of other compounding agents, lubricate the rolling and extrusion, but also reduce the hardness of the vulcanized rubber and improve the performance of the vulcanized rubber (such as tensile strength, elongation, cold resistance, etc.).

Therefore, softeners are of great significance in the processing of both natural rubber and synthetic rubber. Hope mine can help you <>

Do you have any other questions?

There are two types of plastic fillers: incremental fillers (or extenders) and reinforcing fillers (or reinforcing agents).

1. Incremental fillers.

Incremental fillers are mainly used to fill gaps during loading and unloading, and there will be many fewer gaps after use.

2. Reinforcement filler.

Plastic reinforcing agent, also known as reinforcing material, refers to a substance added to the resin that can be tightly combined with the resin and significantly improve the mechanical and mechanical properties of the product.

Reinforcing agents are important materials for the manufacture of reinforced plastics, and the vast majority of reinforcing agents applied now are high-strength fibrous inert substances. Such as glass fiber, asbestos, carbon fiber, boron fiber, ceramic fiber, aramid fiber, stainless steel fiber, whisker and organic fiber, etc.

Summary. Hello dear, no, rubber is soluble in organic solvents. Rubber is a polymer organic compound, according to the principle of similar miscibility, rubber is insoluble in polar solvents, soluble in non-polar organic solvents If my answer is helpful to you, please also give a thumbs up (in the lower left corner of the evaluation), look forward to your like, your efforts are very important to me, your support is also the driving force for my progress.

Finally, I wish you good health and a good mood!

Just tell me what the type of organic solvent of the rubber filler is and what the type of organic solvent corresponds to.

There are many types of organic solvents for rubber fillers, which can be divided into 10 categories according to their chemical structure: Aromatic hydrocarbons: benzene, toluene, xylene, etc.; Aliphatic hydrocarbons:

pentane, hexane, octane, etc.; Alicyclic hydrocarbons: cyclohexane, cyclohexanone, toluene ring.

Hello dear, organic solvent type Rubber is soluble in organic solvents. Rubber is a polymer organic compound, according to the principle of similar miscibility, rubber is insoluble in polar solvents, soluble in non-polar organic solvents. However, the solubility of different types of rubber is not exactly the same.

For example, common natural rubber can be soluble in chloroform and carbon tetrachloride. Synthetic nitrile rubber has strong oil resistance, and common organic solvents are almost insoluble. In addition, it should be noted that the dissolution of polymer socks such as rubber is different from the common solute dissolution.

Due to the large molecular weight of the long chain of polymers, when the polymer is immersed in the solvent, the polymer is not dissolved immediately, and the dissolution process is generally divided into two stages: first, the solvent molecules with small molecular weight and fast diffusion rate penetrate into the polymer, so that the volume of the polymer expands, that is, swelling. Then the polymer molecules diffuse into the solvent and dissolve.

That is to say, in the process of dissolving polymers, they must first go through the swelling stage of Song's before they can be dissolved.

3.In fact, there is a lot of knowledge about plastic filling modification, it is difficult to say it in a few words, you try it first, I wish you success! You should be talking about the production of filler masterbatch, the main components of filler masterbatch are calcium carbonate, additives and.

Petroleum extracts are divided into three kinds according to their composition, linear hydrocarbon oil, naphthenic oil, aromatic oil, the main component of linear hydrocarbon oil is saturated linear hydrocarbons, the main component of naphthenes is saturated naphthenic hydrocarbons, due to the influence of precision in the preparation process, there will be some unsaturated naphthenic hydrocarbons or other components, aromatic oil contains more heterocyclic and fused cyclic hydrocarbons, the polarity is larger, there are three indicators, one is viscosity, one is aniline point, that is, the temperature when the oil is completely dissolved in aniline, the aniline point of aromatic oil is the lowest, and the aniline point of linear hydrocarbon oil is the highestThe rubber with high polarity has good miscibility with low aniline point, and the rubber with low polarity has good miscibility with high aniline point, such as ethylene propylene rubber is generally filled with engine oil, styrene-butadiene rubber is generally filled with aromatic oil, and there is also an iodine value, the number of unsaturated bonds in the oil, indicating the aging resistance of the oil.

Synthetic plasticizers generally look at its 1, solubility parameters (miscibility with rubber, determine the filling variety and filling amount of rubber), 2, molecular weight (solvent extraction resistance after filling, large molecular weight, good extraction resistance, boiling point (oil stability, high temperature resistance), etc

The most commonly used reinforcing agents for rubber are: activated calcium carbonate and Muxun deficiency substance, carbon black silver Chang regret, zinc oxide, white carbon front black, activated clay, the most dosage and the best effect is carbon black.

Filler (English name filler) is also known as filler, filler, filler (additive; addition agent；stuffing bulking agent）。Solid substances that can be added to materials can improve the performance of materials, or can increase capacity and weight, and reduce the cost of materials. Organic, inorganic, inorganic, metallic or non-metallic powders that usually do not contain water, are neutral, and do not play an adverse role with the material components can be used as fillers.

Commonly used industrial fillers are kaolin, diatomaceous earth, talc, graphite, carbon black, alumina powder, glass powder, asbestos powder, mica powder, quartz powder, carbon fiber, powdered cork, emery, etc. A large number of fillers are used in plastic processing, rubber processing, paper, coatings, pesticides, pharmaceuticals and other products in chemical production, which not only improves the performance of these products, but also greatly reduces production costs.
