Description
Technical Field
The invention discloses a wear-resistant anti-skid road surface coating, and belongs to the technical field of building materials.
Background
The anti-skid coating is not strange to people, and anti-skid floors can be seen on pedestrian overpasses, stadiums, ship decks, offshore platforms, water floating bridges and the like. The skid resistance is the basic characteristic of the skid-resistant coating and is a special property of the coating film. The anti-skid coating mainly contains anti-skid granules, film-forming resin and other substances, wherein the anti-skid granules are additives for improving the anti-skid performance of a paint film, endow the paint film with anti-skid capability and prevent people from slipping and falling injury; the film-forming resin has the function of fixing the anti-skid granules and simultaneously protects the substrate from being damaged.
The development and utilization of anti-slip coatings has been in the past for many years. The base material is usually selected from common alkyd resin, chlorinated rubber, phenolic resin or modified epoxy resin, and the resins have good weather resistance and mechanical property. The resin is mixed with hard and large particles, such as cheap quartz sand or the like, and the filler particles are large and protrude out of the surface to generate larger frictional resistance, so that the aim of preventing skid is fulfilled.
The wear resistance is a good performance of the novel functional coating, the coating with good wear resistance can better protect the surface of the material, and the service life of the coating is prolonged. Therefore, although the single anti-skid performance coating has a good anti-skid effect, the coating has low anti-skid performance and short service life after being used for a long time, and cannot achieve a long-term stable anti-skid effect.
The most successful application of the anti-skid coating is that on aircraft carriers and ship-borne decks, the coating increases the friction coefficient of the decks and avoids sliding, the coating can prevent airplanes and vehicles from sliding on the decks when the aircraft carriers are in operation, and due to the special purposes, the development of the anti-skid coating is leap forward, and a special anti-skid coating production and research center is established from a general civil range to special anti-skid research on the aircraft carriers, so that the anti-skid coating has various varieties, wide purposes and high specificity and universality. For example, EPOXO 300C epoxy polyamide anti-skid paint produced by AST center is used for flight decks of all aircraft carriers and more than 90% of large ship decks in navy, is the anti-skid paint with the highest safety guarantee, has large friction force and long durability, and has been applied for 20 years. The alumina type wear-resistant granules with diamond-grade hardness are adopted, the friction coefficient is almost unchanged in water and oil states, the heat and air injection resistance and the chemical resistance are high, and the adhesive force is good. CN103013274A relates to a wear-resistant anti-slip coating, which consists of anti-slip paint slurry and a curing agent, and is characterized in that: the anti-slip paint paste is prepared by mixing 6-8 kg of titanium dioxide, 0.5-1 kg of carbon black, 2-3 kg of lubricant, 1-2 kg of thickening agent, 1-2 kg of anti-settling agent, 20-30 kg of carborundum, 0.5-1 kg of toughening agent and 40-60 kg of hydroxyl acrylic resin; during construction, 10-20 kg of curing agent with the type of N-75 is added into the anti-skid paint paste for mixing. From the above, the wear-resistant anti-skid coating disclosed by the patent application is mainly wear-resistant in performance, poor in anti-skid performance and incapable of being applied to the field with high anti-skid requirements. The traditional anti-skid paint at present has the problem of poor wear resistance, so research on the anti-skid paint is needed.

wear resistance: and testing the abrasion loss. Firstly, calculating the mass of a coating on a steel plate: m1= (total mass-steel sheet mass). A standard 3mm diameter steel bar was placed on the coating and a weight was placed to create (136 ± 0.5) N pressure between the bar and the coating, the bar was first moved back and forth over the coating 50 times, a new bar was then moved back and forth over the coating 50 times, and the change in coating quality before and after 450 times was measured and recorded as m 2. The abrasion resistance of the coating was recorded as Lm = m2/m1 × 100%.
