Problems solved by technology

Because asbestos felt and glass fiber felt are low in strength and easy to crack, they are usually scrapped after a few times of use. In the prior art, composite materials mainly composed of polyethylene have appeared. However, while ensuring their thermal insulation and flame retardancy, these are often The toughness of composite materials is difficult to guarantee, it is easy to age, and the stability of materials is poor. However, while some composite materials improve the toughness of plastics, the material strength, stiffness, modulus and heat resistance are greatly reduced, and it is impossible to achieve simultaneous heat insulation and flame retardancy. The purpose of increasing toughness

Abstract

The present invention provides a heat insulating and flame retardant felt, which is mainly prepared from high density polyethylene, added with glass fiber, wollastonite, montmorillonite, potassium titanate, zinc oxide, an ethylene-propylene-diene monomer, butadiene-acrylonitrile rubber, styrene-butadiene-styrene terpolymer, ethane-octylene copolymer, carbon nano-tube, calcium carbonate superfine powder, polypropylene grafting maleic anhydride, 2, 4, 6-tert-butyl phenol, and a colouring agent. Ingredients of the mixed materials for preparing the heat insulating and flame retardant felt are appropriate, which can overcome problems of poor toughness, low heat resistant grade and so on existed in normal polyethylene composite material felts.

Description

technical field [0001] The invention relates to a heat-insulating and flame-retardant felt, in particular to a heat-insulating and flame-retardant felt made of polyethylene. Background technique [0002] With the continuous development of society and economy, the scale of construction is increasing day by day, especially in some processing fields, flame-retardant felts are required for local heat insulation. Commonly used thermal insulation and flame retardant mats include asbestos felt and glass fiber felt. Because asbestos felt and glass fiber felt are low in strength and easy to crack, they are usually scrapped after a few times of use. In the prior art, composite materials mainly composed of polyethylene have appeared. However, while ensuring their thermal insulation and flame retardancy, these are often The toughness of composite materials is difficult to guarantee, it is easy to age, and the stability of materials is poor. However, while some composite materials impro...
