Enhanced reflective EPE thermal insulating building material

Abstract

The invention discloses an enhanced reflective EPE (Expandable Poly Ethylene) thermal insulating building material comprising an outer aluminum foil layer, a physically foamed flame retardant polyethylene layer and a flame retardant polyethylene woven cloth layer, wherein every two adjacent ones of the outer aluminum foil layer, the physically foamed flame retardant polyethylene layer and the flame retardant polyethylene woven cloth layer are orderly connected integrally through thermal compounding by means of a flame retardant polyethylene layer, and the lower surface of the flame retardant polyethylene woven cloth layer is thermally compounded with the flame retardant polyethylene layer; the bright smooth surface of the outer aluminum foil layer is outward; each of the physically foamed flame retardant polyethylene layer, the flame retardant polyethylene woven cloth layer and the flame retardant polyethylene layer contains polyethylene in a weight ratio of 80-92% and a flame retardant master batch in the weight ratio of 8-20%; and the flame retardant master batch is prepared from a low-density polyethylene base material in the weight ratio of 20-40%, a bromide in the weight ratio of 25-40%, antimonous oxide in the weight ratio of 15-35% and a dispersant in the weight ratio of 10-20% through formulation, and then melting mixing and pelleting. The enhanced reflective EPE thermal insulating building material provided in the invention is high in tensile strength, not easy to age, long in service life, and greatly improved in both heat-shielding performance and flame retardant property.

Description

Technical field [0001] The invention relates to a building material, in particular to a reinforced reflective EPE heat insulation building material. Background technique [0002] Physically foamed polyethylene (EPE, also known as pearl cotton) is composed of low-density polyethylene through physical foaming to produce countless independent bubbles. It has certain water- and shock-proof properties, and is non-toxic and environmentally friendly. As a thermal insulation building material for building roofs, walls and other parts. [0003] Traditional EPE insulation building materials are prone to ageing and have a low service life. Generally, they will gradually lose their waterproof and thermal insulation functions in two to three years; and the simple EPE materials have low tensile strength and tear strength, and are easy to contact with foreign objects or under heavy pressure. It is not convenient in actual construction. [0004] And with the advancement of science and technology a...

AI Technical Summary

Problems solved by technology

Traditional EPE heat insulation building materials have poor surface flatness, low light reflectivity, heat insulation and heat preservation performance can no longer meet the heat insulation performance standards required by many buildings, and the flame retardancy level of traditional EPE heat insulation building materials is not high, and the flame retardant performance Low, the security level can not meet the corresponding requirements
