Lightweight soundproof heat-insulating material and preparation method thereof

Abstract

The invention discloses a lightweight soundproof heat-insulating material, comprising, by weight, 45-65 parts of Portland cement, 20-25 parts of enveloped perlite, 10-15 parts of glass beads, 5-8 parts of trimethylolpropane, 2-5 parts of rosin, 1-2 parts of sodium bicarbonate, 5-20 parts of ethyl acetate, 1-3 parts of dioctyl phosphate, 1-3 parts of natural fiber, 1-3 parts of acrylamide, 1-3 parts of aluminum silicate fiber, 1-2 parts of polyester polyol, 1-3 parts of sodium formate, 1-3 parts of a composite flame retardant, 1-2 parts of a foaming agent, and 0.5-1.5 parts of dispersible latex powder. The lightweight soundproof heat-insulating material has the advantages that by enveloping the expanded perlite, the fire resistance and thermal insulation in expanded perlite are made full use, and the defect of the expanded perlite absorbing water easily is improved; the natural fiber and the aluminum silicate fiber are used as one of materials for the lightweight soundproof heat-insulating material, giving the features of low heat conductivity coefficient and low density, the materials are easy to obtain, and the cost is low.

Description

Technical field [0001] The invention belongs to the field of thermal insulation materials, and specifically relates to a light-weight sound insulation thermal insulation material and a preparation method thereof. Background technique [0002] Insulation materials are widely used in insulation materials of refrigerators, cold storages, freezers, refrigerated vehicles, buildings, storage tanks and pipelines. In recent years, the research on rigid foams abroad has developed rapidly and has been widely used. However, domestic rigid foam plastics are relatively slow in development due to their high cost, so the domestic market needs to be further developed. In addition, thermal insulation materials require not only light weight, but also excellent compressive strength, modulus and dimensional stability. With the development of science and technology and the continuous improvement of living standards, environmentally friendly thermal insulation materials have become an important resea...

Problems solved by technology

[0004] With the progress of society, the country has higher and higher requirements for industrial production or construction. Among them, various materials have put forward requirements for sound insulation, flame retardancy, heat insulation, and warmth. At present, in the fields of industrial production or construction in my country, For some board materials, inorganic foam materials, polymer organic foam materials, etc. are usually used to meet the requirements of sound insulation and heat insulation, but most of those materials are harmful to the human body and are flammable, so it is troublesome to recycle and dispose of their waste.
