Problems solved by technology

PU material is a kind of plastic, its main component is polyvinyl chloride, its elasticity is not good, it is easy to aging and water cracking, the air filter made of it has a short life
The elasticity of the rubber material is better than that of the PU material, but it is still not ideal; the leftovers produced by the two materials when preparing the air filter are not easy to recycle, resulting in a certain waste of resources, not environmentally friendly, and poor flexibility under low temperature conditions; in addition , the use of rubber materials to prepare air filters is usually done manually, which takes a long time and has low efficiency. Due to the volatility of the material, it will also pose a health threat to the operator.

Abstract

The invention provides a biodegradable TPE (thermoplastic elastomer) and a preparation method thereof. The TPE comprises the following components in parts by weight: 100 parts of SEBS (styrene-ethylene-butadiene-styrene), 5-380 parts of white mineral oil, 5-200 parts of PP (polypropylene), 5-100 parts of polyurethane, 0-80 parts of EVA (ethylene-vinyl acetate), 0-100 parts of calcium carbonate, 0-3 parts of calcium stearate, 0.2-1 part of antioxidant, 1-100 parts of maleic anhydride grafted polypropylene, 0-10 parts of titanium dioxide and 1-15 parts of ethylene propylene diene monomer. The TPE provided by the invention has favorable flexibility and high preparation efficiency, is an ideal material for preparing an air strainer, and can be used for mechanical operation, and the scraps can be recycled and reutilized, thereby having an important meaning for saving resources.

Description

【Technical field】 [0001] The invention relates to a method for preparing an air filter, in particular to a method in which an environment-friendly TPE is used for preparing an air filter. 【Background technique】 [0002] The air filters used in the air filters currently used in various fields are usually made of the following two materials, one is PU material and the other is rubber material. PU material is a kind of plastic, and its main component is polyvinyl chloride, which has poor elasticity, is prone to aging and water cracking, and the air filter made of it has a short service life. The elasticity of the rubber material is better than that of the PU material, but it is still not ideal; the leftovers produced by the two materials when preparing the air filter are not easy to recycle, resulting in a certain waste of resources, not environmentally friendly, and poor flexibility under low temperature conditions; in addition , Utilize the rubber material to prepare the air...
