Preparation method of plant fiber/glass fiber-based special thin-sheet substrate

Abstract

The invention discloses a preparation method of a plant fiber / glass fiber-based special thin-sheet substrate. The method comprises the steps that a commercial chemical pulp board is pretreated, fiberis dispersed, base paper is manufactured with pulp, a maceration extract is prepared, and the base paper is macerated and dried. The plant fiber / glass fiber-based special thin-sheet substrate preparedby combining various measures has the advantages that through maceration with different plasticizers, the compactness of the plant fiber / glass fiber-based special thin-sheet substrate is reduced, thebulk of the material is improved, the absorbing quality is better, and the brittleness of the material is ameliorated, so that the plant fiber / glass fiber-based special thin-sheet substrate is difficult to break during construction and better meets the needs for production and life.

Description

technical field

[0001] The invention belongs to the technical field of special paper preparation, and relates to a method for preparing a plant fiber / glass fiber-based special sheet substrate. Background technique

[0002] Plant fiber / glass fiber-based special thin sheet substrate is the raw material for preparing plant fiber / glass fiber-based sound-absorbing and flame-retardant thin sheet materials. It is made of plant fiber and glass fiber in a certain proportion by wet papermaking. After being impregnated with binder, it can endow the substrate with certain strength, which is convenient for production and use. Plant fiber / glass fiber-based sound-absorbing and flame-retardant sheet material is a building decoration material with sound-absorbing and flame-retardant functions. It is made of plant fiber / glass fiber-based special sheet substrate, impregnated with flame retardant, color paste and other impregnating liquids, endowing it with good flame retardancy and decoration...

[0028] A method for preparing a plant fiber / glass fiber-based special sheet substrate, comprising the following steps:

[0029] Step 1, pre-treatment of commercial chemical pulp board: after soaking an appropriate amount of pulp board in water for a certain period of time, disperse the fiber into a uniform fiber suspension with a disintegrator, filter the pulp, wring it out, and balance the water for later use; commercial chemical pulp The board is one of coniferous wood pulp board, hardwood pulp board or bamboo pulp board;

[0030] Step 2, fiber dispersion: put a certain quality of glass fiber and water in a deflagging machine, add a dispersant, and after decomposing for 2w, add the slurry obtained in step 1, and then decompose for 1w to obtain a mixture of glass fibers and plant fibers mixed pulp;

[0031] Step 3, base paper making: copying the mixed pulp with evenly dispersed fibers in step 2 on a paper sample machine;
