Problems solved by technology

The performance of this kind of material has been significantly improved, but according to its traditional molding and vulcanization preparation process, the concrete material with smooth surface is obtained.
Especially CN105174848 and CN104910476, in the process of use, due to the smooth surface, the surface friction is not enough, the wet skid resistance is not high, and it is easy to cause safety accidents of driving or pedestrians
If the surface of the abrasive tool is treated with patterns, it will cause quality problems such as lack of glue and cracking, which will seriously affect the service life of the material

Abstract

The invention provides a preparation method of a rubber concrete panel with a rough surface, and belongs to the field of compound materials. The method specifically includes the steps that treated stone and rubber compound particles are packed into a mold after being mixed evenly, then the mold is covered by a plastic panel with an area equal to that of an upper mold cavity and the thickness of 2-5 mm, an upper mold panel is closed, at 150-180 DEG C, firstly, preheating is conducted for 30-90 seconds, then mold pressing is conducted at 8-18 MPa, and finally, vulcanization is conducted for 10-40 minutes to prepare the rubber concrete panel with the rough surface. The preparation method of the rubber concrete panel with the rough surface has the beneficial effects that through the method, apart of stone on the rubber concrete surface can be made to be raised, not only is the rubber concrete material surface wear resistance improved, but also a surface friction coefficient of a materialcan be increased, and the anti-skid performance is improved, so that the safety of passengers and driving is improved; meanwhile, mold opening after vulcanization is conducted can be made to be easier.

Description

technical field [0001] The invention relates to a method for preparing a rough-surfaced rubber concrete plate, which belongs to the field of composite materials. Background technique [0002] Rubber concrete is mostly made of waste tire rubber powder or granules as part of the aggregate, compounded with sand, gravel, asphalt, etc. Rubber concrete can effectively improve the toughness and deformation resistance of the material, thereby improving the anti-rutting performance. At present, it has a certain range of applications in road paving. CN101519293 discloses a rubber cement concrete and a preparation method thereof; CN105174848 discloses a rubber concrete material and a preparation process thereof; CN104910476 discloses a rubber composite material, a composite plate made of the material and a plate process. The performance of this type of material has been significantly improved, but according to its traditional molding and vulcanization preparation process, a smooth su...
