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 sulphate aluminium cement plant fiber product, being prepared from the following component raw materials in parts by weight: sulphate aluminium cement, bits of wood, silica fume, coal ash, glass fiber, water, retarder, water-retaining agent, thickener and antimitotic agent. The preparing method comprises: (1) weighing the respective component raw materials in parts by weight; (2) adding the sulphate aluminium cement, bits of wood, silica fume, coal ash and glass fiber in to water and stirring, adding the water-retaining agent, thickener and antimitotic agent and stirring, standing; (3) adding the retarder, stirring, conveying into a roller level production workshop, entering a template, filling, performing roller leveling to produce a wet panel, cutting, and then conveying into a curing workshop for curing. The product has a smooth surface, no cracks, no cracking phenomenon, high strength and high durability; further, the product has easily obtained raw materials and low cost and the preparing method is low in cost and easy and simple 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...
