Problems solved by technology
[0007] (2) Rubber is an elastic body. After "rubber-wood fiber" is compounded into a board, it may bring difficulties to subsequent mechanical processing such as sawing, surface sanding, and tenon and groove processing.
[0008] (3) The density of waste rubber is greater than that of wood fiber. How to simply mix the two units will lead to uneven distribution of rubber in the composite board

Embodiment Construction
[0023] Taking waste rubber as an example, the present invention will be described:
[0024] A method for manufacturing an elastic composite floor substrate has the following steps:
[0025] a) Raw material preparation:
[0026] The waste rubber is crushed and screened to obtain rubber particles with a particle size of 30-100 mesh and ultrafine rubber powder with a particle size of 100-200 mesh;
[0027] The rubber particles with a particle size of 30-100 mesh are rolled by a roller to roughen the surface of the particles, and then a dissolving modifier is applied to make the particle surface viscous. The dissolving modifier is acetone, and the amount of acetone applied is the mass of the rubber particles. In addition to acetone, other neutral or weakly acidic solvents that can dissolve rubber can be used as dissolution modifiers;
[0028] Add ultra-fine rubber powder with a particle size of 100~200 mesh as elastic floor adhesive in the synthetic resin liquid adhesive. The synthetic res...

Abstract
The invention relates to an elastic composite floor board base material manufacturing method. The elastic composite floor board base material manufacturing method includes the following steps of firstly, preparing materials by grinding rubber grains with grain diameter of 30-100 meshes via a grinding machine so as to roughen the surfaces of the rubber grains, adding dissolving modifiers so as to stiffen the surfaces of the rubber grains; adding superfine rubber powder with grain diameter of 100-200 meshes into liquid synthetic resin adhesives as elastic floor adhesives; secondly, uniformly mixing the rubber grains, the elastic floor board adhesives and wood fibers and / or grass fibers; and thirdly, pressing the mixture to form floor board base materials in a hot pressing manner. The elastic composite floor board base material manufacturing method has the advantages that by compositing rubber on conventional wood fiber board base materials, elasticity of a reinforced floor board is evidently improved; by melting and modifying the surfaces of the rubber grains, adhering performances of the wood fibers and the rubber grains are evidently enhanced; and the rubber grains can be uniformly distributed in the composite floor board base materials.
Description
Technical field [0001] The invention relates to a method for manufacturing an elastic composite floor substrate, in particular to a method for manufacturing an elastic composite floor substrate composed of rubber, wood fiber and / or grass fiber. Background technique [0002] Laminate flooring, also known as impregnated paper laminated wood flooring, is a wooden floor made of impregnated paper and high-density fiberboard. Due to the mature technology, high cost performance, bright and changeable appearance, it is widely used in various indoor floor pavings. occasion. However, due to the high density of laminate flooring, the density is generally higher than 0.85g / cm 3 , The original porous structure of wood disappears, the elasticity of the product is significantly weakened, especially the ability to cushion impact loads is significantly reduced. In many occasions, such as stadiums and gymnasiums, high-speed movement or sudden jumps of the human body require high elasticity of the...
