Problems solved by technology

[0005] The purpose of the present invention is: in order to solve the problem that the inner cavity of the bubble is not filled, which leads to the reduction of the overall impact resistance of the foamed gypsum, and although the gypsum cavity can be used for sound insulation and noise reduction, the sound wave passes through the cavity without being separated. Therefore, the problem of poor noise reduction effect, and proposed a light weight high strength water-resistant decorative gypsum board and processing method

Embodiment 1

[0034] The invention provides a technical solution: a light-weight, high-strength, water-resistant decorative gypsum board, which is prepared from the following components in parts by weight: 70-80 parts of gypsum powder, 5-10 parts of diatomite, 1 ~3 parts of corn starch, 0.5~3 parts of foam stabilizer, 5~10 parts of granite particles, 3~5 parts of graphene oxide sheets, 3~5 parts of silicon acrylic emulsion, 0.3~0.9 parts of waste paper pulp fiber, 0.5~1.0 parts Cellulose nanofibrils, 0.2-0.4 parts of glass fiber, 3-6 parts of surfactant and appropriate amount of water.

[0035] The surfactant is at least one of an anionic surfactant and an alkyl glycoside sulfonate, and the surfactant can effectively increase the surface tension of the granite particles, preventing it from being dissolved in the graphene hydrogel body of the graphene oxide sheet. Agglomeration, improve the dispersion effect of yellow granite particles.

[0036] The foam stabilizer is sodium lauryl sulfate,...

Embodiment 2

[0051] The difference from Example 1 is that this example also provides a technical solution: a light-weight, high-strength, water-resistant decorative gypsum board, prepared from the following components in parts by weight: 70-80 parts of gypsum powder , 5-10 parts of diatomite, 1-3 parts of corn starch, 0.5-3 parts of foam stabilizer, 5-10 parts of granite particles, 3-5 parts of graphene oxide sheets, 3-5 parts of silicon acrylic emulsion, 0.3- 0.9 part of waste paper pulp fiber, 0.5-1.0 part of cellulose nanofibrils, 0.2-0.4 part of glass fiber, 3-6 parts of surfactant and appropriate amount of water.

[0052] The surfactant is at least one of anionic surfactants and alkyl glycoside sulfonates.

[0053] The foam stabilizer is azodicarbonamide, and the molecular formula of azodicarbonamide is: C2H4N4O2, which is foamed after the gypsum powder is stirred.

[0054] S1. Prepare the raw material components according to the amount, crush the gypsum powder raw material, input th...

Embodiment 3

[0065] Different from the above-mentioned solution, this embodiment also provides a technical solution, a light-weight, high-strength, water-resistant decorative gypsum board, which is prepared from the following components in parts by weight: 70 parts of gypsum powder, 5 parts Parts of diatomite, 1 part of corn starch, 0.5 parts of foam stabilizer, 5 parts of granite particles, 3 parts of graphene oxide sheets, 35 parts of silicon-acrylic emulsion, 0.3-0.9 parts of waste paper pulp fibers, 0.5-1.0 parts of cellulose nanofibers Silk, 0.2-0.4 parts of glass fiber, 3-6 parts of surfactant and appropriate amount of water.

Abstract

The invention discloses a light-weight, high-strength, water-resistant decorative gypsum board and a processing method thereof, which belong to the technical field of gypsum board processing and are prepared from the following components in parts by weight: 70-80 parts of gypsum powder, 5-10 parts Diatomaceous earth, 1-3 parts of corn starch, 0.5-3 parts of foam stabilizer, 5-10 parts of granite particles, 3-5 parts of graphene oxide sheets, 3-5 parts of silicon-acrylic emulsion, 0.3-0.9 parts of waste paper pulp Fiber, 0.5-1.0 parts of cellulose nanofibrils, 0.2-0.4 parts of glass fiber, 3-6 parts of surfactant and appropriate amount of water. In the present invention, the graphene hydrogel can be filled in the foaming air in the foamed gypsum board, and the graphene hydrogel and the inner granite particles can be bonded to the inner cavity of the foaming air, and at the same time, the porous graphene hydrogel can Refract the direction of sound wave transmission, significantly improve the overall impact resistance of gypsum boards, improve the overall isolation effect, and meet the needs of gypsum board decoration.

Description

technical field [0001] The invention belongs to the technical field of gypsum board processing, in particular to a light-weight, high-strength, water-resistant decorative gypsum board and a processing method. Background technique [0002] As the name implies, gypsum board is a material board made of gypsum powder for construction as the main raw material. The gypsum material itself is light in weight, high in strength, impact-resistant, and thin in thickness, which is convenient for cutting and processing the board, and is convenient for personnel to process, and the insulation and sealing of the gypsum itself can have good sound insulation and heat insulation and fire resistance. , is a good building decoration material, and is one of the new lightweight panels that the country is currently emphasizing on development. [0003] The Chinese invention patent publication number is: CN101094822B discloses a kind of foamed gypsum, relates to the method for manufacturing foamed g...
