Insulation board made of fiber reinforced composites and preparation method of insulation board

Abstract

The invention discloses an insulation board made of fiber reinforced composites. The insulation board is characterized in that enhancement layers are paved on an upper layer and a lower layer of an insulation layer, and are of glass fiber gridding cloth. The invention also discloses a preparation method of the insulation board made of fiber reinforced composites. The preparation method comprises the steps of mixing all raw materials of the insulation layer with water uniformly; pouring the slurry mixed uniformly into a mold, wherein the glass fiber gridding cloth is paved at the bottom of the mold; paving a layer of glass fiber gridding cloth on the upper layer of the slurry; after the paving, pressing and molding the slurry. Due to the mode, the double layers of glass fiber gridding cloth are adopted for enhancing, so that the size stability, the shock resistance and the crack resistance of the insulation plate are improved obviously; the requirement on the insulation and fire resistance of an outer wall are met by adopting the technology that inorganic bond materials wrap the insulation fillers; and the service life of the insulation board is long and basically keeps the pace with that of a building.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a fiber-reinforced composite material insulation board and a preparation method thereof. Background technique [0002] Thermal insulation materials and products are an important factor affecting building energy efficiency. The development and application of building insulation materials have been paid more and more attention by countries all over the world. After the 1970s, foreign countries generally paid attention to the production of thermal insulation materials and their application in construction, and strived to greatly reduce energy consumption, thereby reducing environmental pollution and greenhouse effect. The thermal insulation material industry in foreign countries has a long history, most of which are thermal insulation materials for building energy conservation, and new thermal insulation materials are constantly emerging. [0003] However, the existing external w...

AI Technical Summary

Problems solved by technology

[0004] 1. Organic thermal insulation materials or composite organic thermal insulation materials. Organic thermal insulation materials have poor fire resistance. Even if double-sided composite inorganic materials are used, it is difficult to meet the A-level fire protection requirements, and the fire resistance of the thermal insulation material itself cannot be changed, and there are potential safety hazards.

[0005] 2. Rock wool, mineral wool, and glass wool have low tensile strength, less than 0.05Mpa, and poor wind pressure resistance, which is harmful to the human body

[0006] 3. Ceramic insulation board and foam glass have high production energy consumption, are not easy to be popularized in a large area, have high thermal conductivity, poor energy saving effect, and are expensive

[0007] 4. Vitrified microbeads, perlite, etc. have high water absorption and limited resources

[0008] 5. Foamed cement board, the surface is easy to powder, and the construction control is difficult
