Non-toxic whether resistant thermoplastic elastomer material

Abstract

The invention discloses a non-toxic whether resistant thermoplastic elastomer material and the material is prepared by mixing the following raw materials in parts by weight with a high speed blending machine: 20-100 parts of chlorinated polyethylene, 0-80 parts of polyvinyl chloride, 5-80 parts of plasticizer, 1-6 parts of stabilizer, 1-6 parts of lubricant, 0.2-1 part of antioxidant, 1-10 parts of flame retardant, more than 0-1 part of ultraviolet absorbent and more than 0-300 parts of packing. The elastomer material of the invention can replace the all kinds of existing paulins and coated materials and has the advantages of no toxicity, no smell, aging resistance, long service life, environmental friend and low cost; the elastomer material not only has outstanding heat resistance, but also has good low temperature resistant, and the cold brittleness of the material can reach -38 DEG C so that the material can be used normally in northern winter.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a non-toxic and weather-resistant thermoplastic elastomer material, which can be used to make covering materials such as tarpaulins. Background technique [0002] All kinds of tarpaulins for vehicles, goods and tents are generally composed of base fabric and surface coating. At present, the coating material is generally made of polyvinyl chloride (PVC), and rubber, polyurethane plastic or PTFE are used for special functions. Vinyl and other materials. Due to the low price of PVC materials, easy access to raw materials, and mature processing technology, it has become the most common coating material. However, there are following problems in the tarpaulin with PVC as the covering material: (1) the migration and volatilization of the plasticizer in PVC are serious, and it is not suitable for human habitation; (2) it is easy to age and has a short service life; (3) it is h...

AI Technical Summary

Problems solved by technology

However, there are following problems in the tarpaulin with PVC as the covering material: (1) the migration and volatilization of the plasticizer in PVC are serious, and it is not suitable for human habitation; (2) it is easy to age and has a short service life; (3) it is harmful to the environment High destructive power; (4) The low temperature brittleness of PVC film material is -25°C, when the outdoor temperature is lower than -25°C, it cannot be used, so it is not suitable for use in winter in the north

[0003] In foreign countries, PVC coating materials have been eliminated, and polyurethane (PU) coating materials are widely used abroad, but PU is also a material that is relatively easy to age and has a short service life.

Moreover, the price of polyurethane itself is very high, which leads to the high price of coating materials.
