Antiskid coating with elastic deformation function and preparation method thereof

Abstract

The invention discloses an antiskid coating with an elastic deformation function. The coating is prepared from the following raw materials in parts by weight: 55 to 63 parts of organic silicon elastic solvent-free resin emulsion, 8 to 12 parts of iron oxide red, 0.3 to 0.7 part of white carbon black, 0.8 to 1.2 parts of dispersing agent, 12 to 17 parts of quartz sand, 7 to 12 parts of talcum powder, 1.5 to 6 parts of antiskid astringency increasing agent and 9 to 12 parts of HDI curing agent. The organic silicon elastic solvent-free resin emulsion is added into the coating, so that the coating can generate an elastic micro-deformation function to increase friction force so as to realize an anti-skid effect, and an elastic paint film has a protection effect on a human body when the human body falls down. The HDI curing agent and the anti-skid and astringency-increasing agent are added into the coating, so that a paint film has good rigidity, toughness and friction performance while having elasticity, the paint film cannot be deformed or damaged when being impacted by common hard objects, and the coating further has excellent ultraviolet ray resistance, seawater resistance and salt spray resistance and can be widely applied to ship decks and offshore platform facilities.

Description

Technical field:

[0001] The invention relates to the field of coatings, and in particular to an anti-slip coating with elastic deformation function. Background technology:

[0002] The requirements for coatings in the offshore operating environment are relatively stringent. Generally, they are required to have anti-corrosion, anti-ultraviolet, and strong adhesion functions. They are widely used in the fields of national defense, military, offshore exploration, etc. After searching, it was found that the publication number "CN106065286A" discloses a wear-resistant and anti-skid paint for ship decks. However, the anti-skid materials such as metal powder and organic glass chips added therein will cause skin abrasions if a person accidentally falls during use. The coating lacks elastic deformation function and does not have buffering characteristics. It is easy to cause the paint film to break and crack after being impacted by external forces. Summary of the invention:

[0003] In order to solve the above technical problems, the purpose of the present invention is to provide an anti-slip coating with elastic deformation function and a preparation method thereof. Through experiments, the coating has different effects under different component ratios.

[0020] Beneficial Effects

[0021] Compared with the prior art, the advantages of the present invention are:
