Embodiment Construction

[0009] The anti-cracking gypsum board is composed of the following raw materials in parts by weight: 15-25 parts of modified starch, 40-60 parts of natural gypsum, 10-15 parts of plant ash, 10-15 parts of slag cotton, 10-12 parts of coagulant, 2 ~4 parts of paper fiber, 50~60 parts of water, its specific preparation method carries out the following steps in sequence:

[0010] 1) Mix the modified starch, slag wool and natural gypsum and add water with 30-50% of the weight of natural gypsum at the same time, stir for 10-13 hours and then put it into the aging warehouse for aging, the stirring speed is 800-1000rpm, and the stirring time is 9~ 11h, then dried in the sun to obtain aged material with moisture content controlled at 6-8%;

[0011] 2) Add plant ash, coagulant, paper fiber, and remaining water to the aging material obtained in step 1), then put it in a mixer and stir evenly and transfer it to the green body mold for extrusion molding to obtain a shaped billet ;

Abstract

The invention discloses an anti-cracking gypsum board. The anti-cracking gypsum board is prepared from the following raw materials in parts by weight: 15-25 parts of modified starch, 40-60 parts of natural gypsum, 10-15 parts of plant ash, 10-15 parts of mineral cotton, 10-12 parts of a coagulant, 2-4 parts of paper fiber, and 50-60 parts of water. According to the anti-cracking gypsum board, thenatural gypsum, the plant ash and the mineral cotton are used as the raw materials, the production is formaldehyde-free and pollution-free, and a good environmental protection function is realized while the strength and hardness of the gypsum board are ensured.

Description

technical field [0001] The invention relates to the field of building materials used for interior decoration, in particular to anti-crack gypsum boards. Background technique [0002] Gypsum board is widely used in building decoration materials because of its light weight, high strength, sound insulation, heat insulation, fire prevention, and easy processing. The wear resistance of gypsum board is average, and the environmental protection requirements are not high. It is a direction of research in building materials, but its application scope still needs to be developed. Contents of the invention [0003] The purpose of the present invention is to provide an anti-cracking gypsum board, which uses natural gypsum, plant ash and slag cotton as raw materials to produce formaldehyde-free and pollution-free, which ensures the strength and hardness of the gypsum board and has good environmental protection function. [0004] The technical scheme of the present invention is as foll...
