Glass fiber reinforced composite heat-insulation plate, manufacturing method thereof and application

Abstract

The invention provides a glass fiber reinforced composite heat-insulation plate, a manufacturing method thereof and application. Main raw material components of the glass fiber reinforced composite heat-insulation plate include, by weight, from 65 to 85% of glass fibers, from 5 to 10% of high-polymer materials, from 10 to 25% of polypropylene. Emission of any substances harmful for human bodies is avoided, any pollution is prevented, high-temperature resistant and fire protection grade of the glass fiber reinforced composite heat-insulation plate are higher than those of a traditional PV (polyvinyl) or PVC (polyvinyl chloride) polyurethane plate by four times, more importantly, the glass fibrousness of the plate is proper due to the fact that the plate is deeply processed, and the plate has certain flexibility, is fine in tensile property, can be secondarily formed according to different applications, and is widely applied to various fields.

Description

technical field [0001] The invention belongs to the field of green and environment-friendly new materials, and in particular relates to a glass fiber-reinforced composite thermal insulation board and its manufacturing method and application. Background technique [0002] The country's "Twelfth Five-Year" science and technology development plan proposes to focus on the development of advanced green and environmentally friendly new materials. At present, most thermal insulation and fireproof composite materials on the market are polyurethane, foam or rock wool, which have poor softness and tensile properties and cannot be remolded, so they are single-purpose and limited to the construction field. [0003] Glass fiber has the following characteristics: 1) High tensile strength and small elongation (3%); 2) High elastic coefficient and good rigidity; 3) Large elongation within the elastic limit and high tensile strength, so it can absorb large impact energy ; 4) It is an inorga...

Problems solved by technology

[0004] At present, glass fibers are also used in insulation boards. The general structure is to add glass fiber mesh to traditional insulation boards, or to mix glass fibers into stone insulation boards in the construction field. The softness of the above insulation boards is not good, and it cannot be realized. Overmolding, limited application areas
