Problems solved by technology

[0002] At present, the modular production of building boards is more and more popular among people. Modular production of boards has brought a new revolutionary impact to the construction industry, which reduces construction costs and greatly shortens the time for building houses. However, modular production Due to the fast hardening speed and easy demoulding required in the production process, the cement board produced by the existing formula is easy to crack, and the surface smoothness is not high. Surface cracking not only affects the appearance, but also reduces the strength and poor durability.

Abstract

The invention discloses an anti-cracking sulphoaluminate cement and plant fiber product comprising components of raw materials in parts by weight as follows: sulphoaluminate cement, Cynanchum thesioides fibers, silica fume, fly ash, glass fibers, water, a retarder, a water retaining agent, a thickening agent and an anti-cracking agent. The preparation method of the product comprises steps as follows: (1) weighing all components of raw materials in parts by weight; (2) adding the sulphoaluminate cement, the Cynanchum thesioides fibers, the silica fume, the fly ash and the glass fibers to the water with stirring, adding the water retaining agent, the thickening agent and the anti-cracking agent with stirring, and leaving the mixture to stand; (3) adding the retarder with stirring, and sending the mixture to a roller flattening line production workshop, producing a wet plate through mold plate filling and roller flattening, and cutting and sending the plate to a curing workshop for curing. The obtained product is smooth in surface, free of cracks, high in strength and high in durability; further, raw materials of the product are easy to obtain, the cost is low, and the preparation method is simple and easy to operate.

Description

technical field [0001] The invention relates to a plant fiber product and a preparation method thereof, in particular to a crack-resistant sulphoaluminate cement plant fiber product and a preparation method thereof. Background technique [0002] At present, the modular production of building boards is more and more popular among people. Modular production of boards has brought a new revolutionary impact to the construction industry, which reduces construction costs and greatly shortens the time for building houses. However, modular production Due to factors such as fast hardening speed and easy demoulding required in the production process of high-grade cement boards, the boards produced by the existing formula are prone to cracking, and the surface smoothness is not high. Surface cracking not only affects the appearance, but also reduces strength and poor durability. [0003] The information disclosed in this Background section is only for enhancing the understanding of the...
