Problems solved by technology

However, since the rubber powder currently used in rubber concrete is vulcanized rubber, its shape and size have been fixed, and the vulcanized rubber has high elasticity and no plasticity, so it cannot fully flow between sand and gravel, and it is impossible to obtain a concrete material with a truly dense structure.

Abstract

The invention provides a rubber concrete material and a composite board manufactured from the same and a board technology. The rubber concrete material comprises, by weight, 100 parts of stone materials, 2-5 parts of Chemlok adhesives and 15-45 parts of rubber mixed compound particles, the stone materials comprise one or more of basalt, andesite and limestone, and the particle size of the stone materials ranges from 2 mm to 25 mm. The rubber concrete material and the composite board manufactured from the same and the board technology have the advantages that the material is compact, waterproof and excellent in buffering and damping performance, noise is reduced, cracking does not occur at low temperature, flowing does not occur at high temperature, and when the material is used as paving materials for road surfaces and bridge floors, the comfort for pedestrians and the comfort properties of running vehicles can be greatly improved.

Description

technical field [0001] The invention relates to a rubber concrete material, and also relates to a composite plate made of the rubber concrete material and a processing technology of the plate. Background technique [0002] At present, rubber concrete is formed by using waste tire rubber powder or granules as part of the aggregate, and sand, gravel, asphalt, etc. Rubber concrete can effectively improve the toughness and deformation resistance of the material. However, since the rubber powder currently used in rubber concrete is vulcanized rubber, its shape and size have been fixed, and the vulcanized rubber has high elasticity and no plasticity, so it cannot fully flow between sand and gravel, and it is impossible to obtain a concrete material with a truly dense structure. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide a rubber concrete material that...
