Anti-ultraviolet transparent plastic, processing method and application

Abstract

The invention relates to anti-ultraviolet transparent plastic, a processing method and an application. The anti-ultraviolet transparent plastic is prepared by blending an ethylene-vinyl alcohol copolymer and an additive and then carrying out melt extrusion casting. The additive is prepared by the following steps: preparing a nano zinc oxide-phosphorus doped hexagonal boron nitride compound by taking phosphorus doped hexagonal boron nitride, a zinc chloride aqueous solution, a sodium carbonate aqueous solution and the like as raw materials, and forming poly(alpha-naphthylamine) on the surface of the compound. The obtained plastic product can effectively block ultraviolet rays, and is good in visible light permeability and excellent in mechanical property.

Description

technical field [0001] The invention belongs to the technical field of plastic processing, and relates to an anti-ultraviolet transparent plastic, a processing method and an application. Background technique [0002] In recent years, people's material living standards have been significantly improved, and people's high standard requirements for living and working environments are in line with it. Plastic, also known as resin, is a polymer material with a wide range of uses, and it plays a very important role in many fields such as coatings, dyes, adhesives, and textiles. Plastic has the advantages of light weight, non-corrosion and good insulation. It is widely used in the world and has become one of the indispensable materials affecting our life. Especially, the use of plastic as packaging material is still the mainstream of today's society. choose. In recent years, with the improvement of people's material living standards, people have higher requirements for plastic pac...

Problems solved by technology

In order to solve this problem, the easiest way is to use black plastic packaging, but the aesthetics are greatly reduced, and it is difficult to meet the high aesthetic requirements of transparent packaging

[0004] People try to apply anti-ultraviolet additives in plastic processing. At present, the four types of anti-ultraviolet commonly used have their own shortcomings: light shielding agents mainly include carbon black and TiO 2 Particles, which make the material opaque after being added; commonly used ultraviolet absorbers and free radical scavengers have certain toxicity; quenchers are mainly complexes or metal salts, which are highly toxic

Therefore, most of them cannot meet the two requirements of transparency and environmental protection and non-toxicity at the same time, which seriously restricts the development of anti-ultraviolet plastic products.

In addition, the compatibility of anti-ultraviolet additives is also a problem that cannot be ignored. Once the compatibility is not good, it will directly affect the mechanical properties of the product.
