A kind of preparation method of multifunctional flame-retardant hydrophobic non-wood fiberboard

Abstract

The invention discloses a method for preparing a multifunctional flame-retardant hydrophobic non-wood fiberboard, which includes the following steps: (S1) Preparation of the first mixed solution: taking 28% NH3·H2O and adding it to ethanol and stirring evenly to form the first mixed solution , (S2) Preparation of the second mixed solution: Dissolve TEOS, GPTMS, and FAS in ethanol to obtain the second mixed solution. (S3) Preparation of modified superhydrophobic silica sol: drop the second mixed solution into the first mixed solution Polymerization reaction at room temperature to form modified superhydrophobic silica sol, (S4) preparation of flame retardant superhydrophobic sol, (S5) raw material preparation of straw fiberboard: including non-wood fiber, (S6) preparation of straw fiberboard and (S7) flame-retardant superhydrophobic surface coating: disperse the flame-retardant superhydrophobic silica sol to form a uniform colloid, evenly spray on the surface of the fiberboard wool board, dry, and cure to obtain a flame-retardant superhydrophobic non-wood fiberboard. The invention effectively improves the adhesive effect and waterproof and fireproof performance, and saves production steps and costs.

Description

A kind of preparation method of multifunctional flame retardant hydrophobic non-wood fiberboard technical field The present invention relates to fiberboard manufacturing technical field, particularly a kind of preparation method of non-wood fiberboard, especially The invention relates to a preparation method of a multifunctional flame-retardant and hydrophobic non-wood fiberboard. Background technique Fiberboard, also known as density board, takes wood fiber or other plant fiber as raw material, and applies urea-formaldehyde resin or its He applies adhesives made of wood-based panels. Adhesives and / or additives may be applied during the manufacturing process. fiberboard material It has the advantages of uniform quality, small vertical and horizontal strength difference, not easy to crack, etc., and is widely used. It takes about 2.5 to 3 cubic meters to manufacture 1 cubic meter of fiberboard can replace 3 cubic meters of sawn timber or 5 cubic meters of logs. Th...
