Embodiment Construction

[0013] The present invention will be further described below in conjunction with embodiment:

[0014] A cement straw composite board and its production process. The composite board uses crop straws (cotton stalks, wheat straws, corn stalks, sorghum stalks, and hemp stalks) as reinforcing materials, cement as a binder and special additives, and Agent and water, paving after stirring, pressing and clamping, heating and curing, mold unloading, edge sawing, and normal temperature curing to obtain the finished product. Cement composite panels can be widely used in ceiling panels, exterior wall panels, and roof panels of various buildings.

[0015] A kind of cement straw board of the present invention is realized like this:

[0016] (1) After cutting, crushing and sieving plant fibers and crop straws (such as wheat straw, etc.), these crop straws are cut and hammered to form narrow and thin fiber scraps, with a width of 1-2 mm and a length of 1 ~15mm, sent to the raw material bin ...

Abstract

The invention relates to a cement straw composite plate and a production technological method. The composite plate finished product is prepared by taking crop straws (cotton stalks, wheat straws, corn stalks, sorghum stalks and hemp stalks) as an enforcement material, taking cement as an adhesive, adding a special additive, mixing with an auxiliary agent and water, and performing stirring, paving, compacting and mold locking, heat curing, demolding, trimming and normal-temperature curing. The cement composite plate is widely applicable to suspended ceiling plates, exterior wall plates and roof board plates of various buildings, has the characteristics of wood and concrete, and also has excellent mechanical properties.

Description

technical field [0001] The invention relates to a composite board and a production process thereof, in particular to a cement straw composite board and a production process thereof. Background technique [0002] Straw, as an appendage of crops, is rich in resources. Some people try to use crop straw and its fibers to make boards, but the straw MDF produced has defects in strength and water resistance, which restricts the sustainable use of straw. At present, with the rapid development of the social economy, the demand for building materials has increased significantly, and the cement composite board has good physical and mechanical properties, waterproof and fireproof performance, and is a new type of decoration material with excellent comprehensive performance. The production and processing technology is relatively backward, and the production capacity is low, which cannot meet the demand of the market. Contents of the invention [0003] The purpose of the present invent...
