Abstract

The invention provides a pottery sand composition for preparing the ground layer of a roller skating field, which comprises component A and component B, and component A comprises: 2.0-4.0 parts of cement and 3.0-5.8 parts of pottery sand aggregate in terms of parts by mass , 0.8-2.1 parts of antistatic materials, 0.1-0.9 parts of pigments, 0.5-2.0 parts of additives; component B contains: 3.0-5.2 parts of styrene-acrylic emulsion, 2.0-3.5 parts of pure acrylic, 0.8-2.0 parts of polyol 1.7 parts, 0.2-1.1 parts of dispersants, 0.1-0.8 parts of film-forming agents, 0.1-0.6 parts of defoamers, 0.2-1.5 parts of pigments; also provide the method for preparing the roller skating field surface layer by using the pottery sand composition The surface layer of the roller skating rink prepared in this way. The pottery sand composition of the invention is environmentally friendly and convenient for construction, and the ground layer of the site prepared by it is anti-slip, impact-resistant, anti-static, high in strength and has certain toughness.

Description

technical field [0001] The invention belongs to the field of coatings, in particular, the invention relates to a pottery sand composition used for preparing the surface layer of a roller skating field. Background technique [0002] Roller skating refers to activities such as training, competition, performance, fitness, and leisure that use various roller shoes, boards and other equipment, including roller skating, roller skating balls, extreme roller skating, skateboards, bicycles, etc. Roller skating is a relatively intense sport. It has strict requirements on the playing field. It requires the playing field to have good anti-slip and wear resistance, and it also requires that it should not affect the athlete's competition speed. Therefore, the materials used in the playing field There are high technical requirements. [0003] The materials used for the ground layer of the existing roller skating arena generally adopt common concrete floor, asphalt floor, marble floor, acr...
