Problems solved by technology

[0004] The technical problem mainly solved by the present invention is that the current common epoxy resin bridge deck non-slip pavement has a large difference in thermal expansion coefficient with the steel plate and poor thermal compatibility, resulting in low elongation and low elongation of the final pavement material. The defect of low bonding strength provides a preparation method for steel bridge deck anti-skid pavement materials

Abstract

The invention relates to the technical field of preparation of building materials and particularly relates to a preparation method of an antiskid paving material for a steel bridge surface. The preparation method takes biological viscous mud as a raw material, the steel bridge surface produces corrosive pitting under a scale through the viscous mud, the roughness of the bridge surface is improved, more anchorage points are formed between the paving material and the bridge surface, the ground touching performance of the paving material is improved, meanwhile, the adhesion strength of the paving material and the bridge surface is also improved, a converter steel slag is taken as a wear resistant filler, a waste tire is used as a toughening filler, the addition of the steel slag weakens the coefficient of thermal expansion between the paving material and a steel plate, the adhesion force of the paving material and the bridge surface is further improved, a waste tire powder is used as the toughing material, a soft segment molecule penetrates through and is inserted into a resin matrix, the internal stress of a system is reduced, when a solid product is stretched, the synergistic effect of an interpenetrating polymer network structure is shown, so that the elongation of the paving material is increased, and the preparation method has a broad application prospect.

Description

technical field [0001] The invention relates to the technical field of building material preparation, in particular to a preparation method of a steel bridge deck anti-skid pavement material. Background technique [0002] Wear-resistant and non-slip multi-layer epoxy paving material for bridge deck is a new type of bridge deck surface material, which is composed of modified epoxy resin, curing agent and wear-resistant and non-slip aggregate. After a specific paving process, the ground system can form a light, flexible, durable and highly wear-resistant non-slip surface. Good bonding performance. Depending on the color of the surface aggregate, it can form a colorful coating surface, and it is gradually being used in various bridges, lifting platforms, parking lots, cargo handling areas, etc. However, the thermal expansion coefficient of ordinary epoxy glue and steel plate is quite different, and the thermal compatibility is poor. In the case of environmental temperature ch...
