Problems solved by technology

[0002] At present, there are many types of external thermal insulation materials for external walls on the market, but they have the following defects: low efficacy; prominent contradiction between light weight and strength; poor thermal performance; backward construction technology for structural safety and surface crack prevention; flame retardant Poor performance; no anti-ultraviolet function; comprehensive coordination of supporting materials and cost reduction is serious
[0003] Now a large number of materials used in external wall insulation are EPS board and XPS board. The bonding between these two types of products and the base layer of the wall is not good, there is hollowing phenomenon, the connection part of the board is easy to crack, and the flame retardancy is extremely high. Difference
Other conventional EPS granular insulation materials have slow condensation speed, poor cohesiveness, low strength, and no anti-ultraviolet function

Abstract

The invention relates to a heat-insulating layer of a rare earth complex wall body and the manufacturing method of heat-insulating layer material, which belongs to the field of architectural materials. The invention is characterized in that the process for preparation comprises mixing rare earth rubber powder by weight ratio that rubber powder: water = 1:1 to 1.5, adding polyphenyl particles intomaterial which is mixed, the proportion is that rubber powder: EPS particles = 1 kg: 8 L, continuously mixing for 5-10 min to make rare earth rubber powder EPS particle heat-insulating material, mixing rare earth trowel finish sand with water according to the proportion that rare earth trowel finish sand: water = 1: 1 into slurry, making rare earth trowel finish sand slurry, and brushing rare earth rubber powder EPS particle heat-insulating material, trowel finish sand slurry, standard net cloth, rare earth trowel finish sand slurry, flexible putty and face coat on the base layer of the wall body in turn. The invention has good heat-insulating property, strong binding power, high compression strength, good water resistance and flame proof, which is antiseptic, noncorrosive, nontoxic, tasteless and pollution-free, has the function of absorbing ultraviolet ray and infrared ray, and has quick coagulate speed, rapid increase of the strength of materials, and the construction procedure is rapid, timesaving and laborsaving.
