Embodiment 1

[0011] Composite thermal insulation, fireproof and sound-absorbing ecological gypsum board, its raw materials include α-type hemihydrate gypsum, which is characterized in that: it also includes gypsum whiskers and closed-cell perlite, and the water-mixed slurry of the three raw materials is rolled by self-leveling vibration It is molded on the production line by means of pressing, and the weight ratio of the three raw materials is: 60% of α-type hemihydrate gypsum, 30% of gypsum whiskers, and 10% of closed-cell perlite.

[0012] The high-grade decorative thermal insulation and energy-saving exterior wall and interior wall panels produced by this process have the advantages of light weight, good strength, and high flexural resistance, reaching the A-level fire protection ecological environmental protection product standard.

Embodiment 2

[0014] Composite thermal insulation, fireproof and sound-absorbing ecological gypsum board, its raw materials include α-type hemihydrate gypsum or β-type hemihydrate gypsum, which is characterized in that it also includes gypsum whiskers and vitrified microbeads or foam particles, mixed with water to form a flowable slurry Casting and rolling molding are carried out on the production line, and the weight ratio of the three raw materials is: 50% of α-type hemihydrate gypsum or β-type hemihydrate gypsum, 35% of gypsum whiskers, and 5% of closed-cell perlite.

Embodiment 3

[0016] Composite thermal insulation, fire-proof and sound-absorbing ecological gypsum board, its raw materials include α-type hemihydrate gypsum, which is characterized in that it also includes gypsum whiskers and vitrified microbeads or foam particles, plus an appropriate amount of water mixed into a flowable slurry on the production line Carry out pouring, rolling, forming and drying, and after forming and drying, the board is laminated on both sides. The material of the laminate is aluminum foil paper; the weight ratio of the three raw materials is: α-type hemihydrate gypsum or β-type hemihydrate gypsum 40%, Gypsum whiskers 50%, closed cell perlite 10%.

[0017] The advantage of this kind of thermal insulation and energy-saving board is that different regions require thermal insulation and energy conservation to produce insulation boards of different thicknesses to meet the requirements of energy-saving and thermal insulation for external wall insulation and internal wall i...

Abstract

A heat-insulation fireproof sound-absorbing ecological gypsum board made of composite materials utilizes alpha-hemi-hydrated gypsum or beta-hemi-hydrated gypsum as a raw material, and is characterized by further utilizing gypsum whiskers and light materials (pearlite, glazed hollow beads or foam particles) as raw materials. The gypsum board is prepared by pouring, forming by rolling and drying mixed slurry of the three raw materials and water, and the gypsum board comprises, by weight, 20-80% of the alpha-hemi-hydrated gypsum or beta-hemi-hydrated gypsum, 10-65% of the gypsum whiskers and 5-20% of the light materials. The gypsum board can serve as a heat-insulation energy-saving board for an outer wall and an inner wall, a fireproof sound-absorbing tunnel board, a ceiling board and a decorative board, has the advantages of lightness, high strength, fine bending resistance and capability of reaching standards of a level-A fireproof ecological environment-friendly product, heat-insulation boards in different thickness can be produced according to heat-insulation and energy-saving requirements of different regions so as to meet the requirements on heat insulation and energy saving, and the fireproof heat-insulation boards in industrialized production are guaranteed to meet the requirements on energy saving and quality in installation and construction.

Description

technical field [0001] The invention relates to a building decoration thermal insulation material, in particular to a lightweight thermal insulation gypsum board. Background technique [0002] In the current building decoration industry, the performance requirements for decorative materials are becoming more and more stringent, especially the requirements for fire resistance, light sound absorption, moisture resistance, and heat preservation of materials are getting higher and higher. Our country advocates the development of inorganic materials as insulation materials. Material. Because these properties are directly related to the safety of buildings, they are of great significance to the protection of property and personal safety. At present, the most widely used products are gypsum products and asbestos products, both of which have good fireproof and thermal insulation properties. However, due to the pollution of asbestos products to the environment, its use range i...
