What products can be made of adhesive composites

There are many kinds of composite materials, the following are examples: Flooring, composite flooring is mostly made of wood chips adhesive extrusion, high water absorption, high VOC content, damp and easy to deform and crack slag. Water pipes, because composite water pipes are composed of different materials, it is necessary to take into account the connection process of the two materials, and it is difficult to "have both fish and bear's paws".

Therefore, generally take the kind of material that is easier to connect and connect more reliably, and the other one only plays the role of hygienic strengthening. Improper connection handling can easily cause delamination. Stone, because some marble ** expensive, so the appearance of "composite marble".

The principle is to combine the stone sheet and the tile masterbatch together, the surface is a thin layer of stone (about 5mm), and the bottom is the tile brick. In this way, the stone is saved, the cost is saved, and the appearance is not affected. However, this composite stone has a disadvantage that it cannot be chamfered, and it cannot be processed for the paving of the sunny corner.

Composites are materials in which two or more materials have their own forms, combining the advantages of each component material but also retaining the disadvantages of each material.

First of all, we must understand what plastic is.

Concept: 1) Plastic raw materials: the main ingredient is resin, which is a material that is infiltrated into various auxiliary materials or additives by polymer synthetic resin as the main ingredient, which has plasticity and fluidity under specific temperature and pressure, and can be molded into a certain shape and keep the shape unchanged under certain conditions;

2) Plastic has good insulation properties for electricity, heat and sound: electrical insulation, arc resistance, heat preservation, sound insulation, sound absorption, vibration absorption and sound attenuation.

3) Most of the plastic raw materials are extracted from some oils, and the most familiar part of the PC material (polycarbonate plastic) is extracted from petroleum, and the PC material has a gasoline smell when burned; ABS (acrylonitrile-butadiene-styrene copolymer plastic) is extracted from coal, and ABS will be soot-like when burned and extinguished; POM (Polyoxymethylene Plastic) is extracted from natural gas, and POM will have a very smelly gas smell when it is burned.

Characteristics of general plastic raw materials:

1) Plastic raw materials are heated and expanded, and the linear expansion coefficient is much larger than that of metal;

2) The stiffness of general plastic raw materials is an order of magnitude lower than that of metal;

3) The mechanical properties of plastic raw materials will decrease significantly under long-term heating;

4) Generally, the plastic raw material will be permanently deformed under long-term stress at room temperature and under stress lower than its yield strength;

5) Plastic raw materials are sensitive to notch damage;

6) The mechanical properties of plastic raw materials are usually much lower than those of metals, but the specific strength and specific modulus of some composite materials are higher than those of metals.

7) Generally, the mechanical properties of enhanced plastic raw materials are heterogeneous;

8) Some plastic raw materials will absorb moisture and cause changes in size and performance;

9) Some plastics are flammable.

Classification of plastic raw materials.

According to the molecular structure of synthetic resins, plastic raw materials are mainly divided into thermoplastics and thermosetting plastics: for thermoplastics, plastics that are still malleable after repeated heating: mainly PE PP, PVC PS, ABS, PMMA, POM, PC PA and other commonly used raw materials.

Thermosetting plastics mainly refer to plastics made of heat-hardened synthetic resins, like some phenolic plastics and amino plastics, which are not commonly used.

According to the scope of application, there are mainly general plastics such as PE PP, PVC, PS, etc., and engineering plastics such as ABS, POM, PC, PA, etc. In addition, there are some special plastics, such as high temperature and humidity resistance, corrosion resistance and other plastics modified for special purposes.

Now you should understand, plastic does not belong to plastics, but its main component is resin, and the main component of plastic is also resin, the two are just the main components are the same, not the same thing.

Instant bonding. Instantaneous adhesive does not need to be heated or pressurized when used, and has the characteristics of fast curing and high bonding strength. One square centimeter of adhesive surface is enough to lift a car.

Such adhesives play a great role in promoting the continuous production line.

Bonding of structural parts. Bonding of structural parts refers to the bonding of those objects that can withstand loads and greater stress for a long time, such as buildings, vehicles, ships, aircraft, spacecraft and other structural parts. increase speed; At the same time, the surface of the adhesive parts is smooth and flat, which is conducive to navigation; It also has sealing, anti-corrosion and other properties.

Liquid seal plugging. Some adhesives are fluidic liquids at room temperature, which are applied to various connections or parts that need to be sealed, forming an elastic adhesive layer, which can replace the usual gasket and play a sealing role.

Underwater bonding. It is manifested in the construction of dams or bridges, the shipbuilding industry and the defense industry, it can connect prefabricated parts on land with components in and under the water, thereby greatly simplifying the construction process and speeding up the construction progress.

Oil surface bonding. The glue for oil surface does not need to be degreased on the surface first, simplifying the process and having good adhesive strength.

Hot melt bonding. A hot melt adhesive is a solid that can only be glued after it is heated and melted into a fluid, and the bond is cooled back to a solid to form a strong bond. Hot melt adhesives are formulated from thermoplastic polymers with tackifiers, etc.

High temperature bonding and ultra-low temperature bonding. Typical adhesives can withstand temperatures below 100 °C. The inorganic adhesive can withstand about 600 meters, among which the ceramic adhesive is the best, which can withstand 1300 high temperatures.

Cryogenic adhesives retain high strength and toughness at -196 or even lower temperatures of -269.

Pressure-sensitive bonding. This product is used for the application of commodity labels, the sealing of cartons, the bundling of wire harnesses, and the protection of the surface of high-gloss metal sheets.

Medical bonding. Medical adhesives have become an indispensable new material in medical treatment. For example, it can play a good role in the adhesion of the kidney, the joint of blood vessels, the anastomosis of wounds, esophagus or biliary tract, the bonding and repair of dentistry, and the connection of bones.

In addition, there are conductive adhesives for the conductive bonding of electronic device leads, and conductive adhesives that use silver powder as conductors. Optical glass adhesives with high transparency and light-sensitive photocuring adhesives and electron beam curing adhesives for optical glass bonding.
