Abstract

The invention provides an inorganic microbead foaming modified silicon-plastic composite thermal insulation material which is prepared from various raw materials including Portland cement, sulphoaluminate cement, inorganic microbeads, fibers, water, a polymer, a water reducing agent, a water repellent, organic particles, a foaming agent, a foam stabilizer and an accelerator. The invention furtherprovides a preparation method of the inorganic microsphere foaming modified silicon-plastic composite thermal insulation material. The foamed cement is used as a silicon material in the silicon-plastic composite thermal insulation material, the organic particles are used as a plastic material in the silicon-plastic composite thermal insulation material, and the inorganic microbeads and the organicparticles with relatively small thermal conductivity coefficients are embedded into the foamed cement, so that the thermal conductivity coefficient of the silicon-plastic composite thermal insulationmaterial is increased to 0.035-0.048 W / (m.k). By adopting the principle of fire prevention, organic particles are wrapped by inorganic materials so that the fire prevention grade is improved to the Agrade, and the polymer is added, so that the product has the advantages of flexibility, water resistance, aging resistance, high strength, difficulty in damage and the like.

Description

technical field [0001] The invention relates to the technical field of building thermal insulation materials, in particular to an inorganic microbead foamed modified silicon-plastic composite thermal insulation material and a preparation method thereof. Background technique [0002] At present, the insulation materials used in domestic external wall insulation systems are mainly organic foam boards, which are easy to burn, and the combustion performance grades are all at B1 or B grades, which is difficult to meet the A-class fire protection standards. [0003] Plastics can be mixed with other materials to make various types of composite materials, such as wood-plastic composite materials, bamboo-plastic composite materials, stone-plastic composite materials, and silicon-plastic composite materials. For example, wood-plastic composite materials are made of polyethylene, polypropylene and polypropylene. Vinyl chloride, etc., instead of the usual resin adhesive, mixed with more...
