Abstract

The invention discloses a composite board and a production method thereof, and relates to the field of building materials. The composite board comprises a bamboo veneer surface layer, and glue-dipped paper layers and kraft paper which are sequentially and repeatedly arranged, or glass fiber net layers, glue-dipped paper layers and bamboo veneer layers which are sequentially and repeatedly arranged, wherein all the layers are pressed and connected together through high temperature and high pressure, large-molecular-weight glue is adopted for the first glue-dipped paper layer under the bamboo veneer surface layer, and small-molecular-weight glue is adopted for the rest of the glue-dipped paper layers. The production method of the composite board includes the following steps of firstly, conducting high-temperature desugaring and degreasing on the bamboo veneer layers except the bamboo veneer surface layer; secondly, attaching non-woven fabric or a glass fiber net to the back face of the bamboo veneer surface layer; thirdly, drying and balancing all the bamboo veneer layers processed in the first step and the second step; fourthly, absorbing fire retardant from the dried and balanced bamboo veneer layers through the negative pressure mode; fifthly, sequentially, repeatedly and flat laying the bamboo veneer surface layer, the glue-dipped paper layers and the kraft paper or laying the glass fiber net layers, the glue-dipped paper layers and the bamboo veneer layers on a pressing machine layer by layer, and closely pressing all the bamboo veneer layers and the kraft layers or pressing the glass fiber net layers and the glue-dipped paper together through pressure of the pressing machine. By means of the technical scheme, the composite board has effects of water prevention, fire retardance and high strength.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a composite board and a production method thereof. technical background [0002] Existing composite boards, such as fireproof boards, are made of base paper (titanium powder paper, kraft paper) impregnated with melamine and phenolic resin at high temperature and high pressure. They are not real bamboo and wood materials, and have the disadvantages of not being waterproof and having poor impact resistance; Bamboo and wood materials, laminate flooring materials, etc., in terms of their materials, have the disadvantages of not being waterproof, not flame-retardant, and having poor impact resistance. They will swell, deform, twist, and break when exposed to water. Produce mold, mites, etc., which is not conducive to human health; Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the object of the present invention is to disclose a composit...
