Halogen-free rubber and plastic thermal insulation material and preparation method thereof

Abstract

The invention provides a halogen-free rubber and plastic thermal insulation material and a preparation method thereof, and belongs to the field of polymer rubber and plastic foaming. Nitrile rubber and an ethylene-butyl acrylate copolymer are adopted as framework materials, a foaming agent, a flame retardant, a plasticizer, a reinforcing agent, a stabilizer, an accelerant, an activating agent, an anti-aging agent, a lubricating agent, a vulcanizing agent, a scorch retarder and other raw materials are added, and the halogen-free rubber and plastic thermal insulation material is prepared through vulcanization foaming. The halogen-free rubber and plastic thermal insulation material prepared by the invention has the advantages of no halogen, no corrosion to metal, small smoke yield in the combustion process, low thermal conductivity, high flame retardance, good elasticity and the like.

Description

technical field [0001] The invention relates to the field of polymer rubber and plastic foaming, in particular to a halogen-free rubber and plastic thermal insulation material and a preparation method thereof. Background technique [0002] With the country's green and sustainable development needs, buildings have higher and higher requirements for energy conservation. The use of thermal insulation materials can effectively reduce energy consumption, achieve energy conservation and emission reduction, and meet the requirements of green buildings. Traditional rubber and plastic insulation materials are mostly obtained by vulcanization and foaming by using nitrile rubber, polyvinyl chloride, chlorinated paraffin combined with foaming agents, vulcanizing agents, flame retardants and other additives. This type of foam material contains some halogens. When used in a humid environment, the halogen will corrode the metal pipe and reduce the service life of the metal pipe. At the sam...

Problems solved by technology

If no cross-linking agent is added to the rubber, it will not be able to form a network structure. Not only will the cells formed during the foaming process be unstable and easily broken, which will have a great impact on its thermal insulation performance, and will also affect the compression rebound of the product. and tear resistance

In addition, no accelerator is added to the application formula, which will reduce the production rate
