AI Technical Summary

Problems solved by technology

[0004] 1) Excessive reliance on urea-formaldehyde resin to increase bond strength and density, resulting in excessive formaldehyde content;
[0005] 2) In order to increase the density and strength, it is usually necessary to use long fibers, resulting in poor uniformity of the produced high-density board
[0006] 3) Conventional MDF has low water resistance and fire protection rating, so it is not suitable for excessive use indoors
Although this method reduces the production cost to a certain extent, it can be seen from its material ratio that the consumption of wood fiber has reached 7-8 times that of lightly burned powder. Therefore, the effect of lightly burned powder on reducing the amount of wood fiber is limited. In turn, the impact on production costs is relatively limited

Abstract

The invention discloses a water-resistant, fire-resistant and environment-protecting carbon fiber board and a preparation method thereof. The density board comprises the following components of 26.5-27.5 parts of a linking agent, 37.5-38.5 parts of wood fibers, 16.5-17.5 parts of urea-formaldehyde resin, 6.5-7.5 parts of natural charcoal particles, 8.5-9.5 parts of paraffin and 0.9-1.1 parts of ammonium chloride, wherein the linking agent is prepared from nano SiO2, nano diatom ooze, a phase solvent and a catalyst. The preparation method comprises the process steps of preparation of the linking agent and a mixture, drying, preparation of a board blank and post-treatment. According to the density board and the preparation method, the linking agent is creatively introduced, and the linking agent has the self-adhesion effect, so that the usage amount of the urea-formaldehyde resin is effectively reduced, and the formaldehyde content in the product is greatly reduced; formaldehyde can be adsorbed and treated, so that the environment-protecting performance of the product is greatly improved; and moreover, part of the wood fibers are replaced by the linking agent, so that the productioncost is favorably reduced.

Description

Technical field [0001] The invention relates to the technical field of building decoration boards, in particular to a water-resistant, fire-resistant and environmentally friendly carbon fiber board and a preparation method thereof. Background technique [0002] Density board is a kind of board. According to the raw materials, it can be divided into fiber density board, glued density board, particle density board and so on. Fiber density board is made by immersing wood, branches and other objects in water and then crushing and pressing. It is made of wood fiber or other plant fibers, applied with urea-formaldehyde resin or other applicable adhesives, and then pavement, molding and high temperature, Man-made panels made of heat conduction and other processes. Particleboard MDF is made of wood or other lignocellulosic materials. After applying adhesive, it is glued under the action of heat and pressure. It is also called particle board. It is mainly used in furniture and constructi...
