Fabricated roof waterproof thermal insulation material and preparation process thereof

Abstract

The invention discloses a fabricated roof waterproof thermal insulation material. The fabricated roof waterproof thermal insulation material is prepared from the following raw materials in proportion: 520 g of silicate, 50 g of an anti-permeability agent, 1 g of organosilicon hydrophobic powder, 10 g of cellulose, 2 g of a powdery defoaming agent, 3 g of a water reducing agent, 4 g of an early strength agent, 100 g of waterproof styrene-acrylic emulsion, 2 g of a preservative, 2 g of a wetting agent, 2 g of a liquid defoaming agent, 60 g of ammonia water, 3 g of a plugging agent, 1 g of a flame retardant and 3 g of a vinyl acetate-ethylene copolymer. By adding tallow amine polyoxyethylene ether, octadecyl hydroxypropyl sulphobetaine, nano silicon dioxide aerogel and cetearyl glucoside into the material, the material has excellent heat resistance, wear resistance, water resistance and weather resistance and good heat preservation and heat insulation performance, and by adding the flame retardant into the material, the heat preservation and heat insulation performance of the material is improved. According to the present invention, with the anti-blocking agent, the material has characteristics of good flame retardant property, good use ductility, good water resistance under the action of the anti-blocking agent, and increase of the water resistance of the material.

Description

technical field [0001] The invention relates to the field of building waterproofing, in particular to a prefabricated roof waterproofing thermal insulation material and a preparation process thereof. Background technique [0002] The prefabricated roof waterproof and thermal insulation material is a waterproof and thermal insulation material for the prefabricated roof. It is mainly to increase the gas phase porosity and reduce the thermal conductivity and conductivity. High elasticity of materials and good durability of inorganic materials; [0003] However, the existing prefabricated roof waterproof and thermal insulation materials do not have excellent heat resistance, wear resistance, water resistance and weather resistance, and the thermal insulation performance is not good enough; secondly, the existing prefabricated roof waterproof and thermal insulation materials do not have relatively Good flame retardant performance, not good use ductility, waterproof performance i...
