Problems solved by technology

[0003] Since domestic research on plant fiber / glass fiber-based sound-absorbing and flame-retardant thin sheet materials started relatively late, although some basic research has been carried out and some progress has been made, there are still many problems in the production practice process, especially with Compared with foreign products, domestic sound-absorbing and flame-retardant products have shortcomings such as high tightness, poor bulk, poor softness, high brittleness, and easy moisture absorption. High-end plant fiber / glass fiber-based sound-absorbing and flame-retardant sheet materials have long relied on imitation and import

Embodiment 1

[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;

[0032] Step 4, preparation of dipping solution: tak...

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...
