Method for preparing hot-melt quick-drying colorful pavement antiskid paint

Abstract

The invention discloses a method for preparing a hot-melt quick-drying colorful pavement antiskid paint. The preparation process comprises the following steps of: (1) putting modified thermoplastic acrylic resin together with smashed and sieved aggregate, plasticizer, pigment and stuffing into a hot-melt kettle and uniformly stirring the mixed materials; (2) adding mixed granular calcium carbonate and superfine calcium carbonate powder into the hot-melt kettle; (3) adding an activated water-based paint quick-drying agent into the hot-melt kettle; and (4) fully re-stirring all the materials in the hot-melt kettle, uniformly blending the materials, detecting and packaging the mixture to obtain finished products. In the invention, the modified colorless and transparent thermoplastic acrylic resin is used as the main raw material, dioctyl phthalate serving as the plasticizer is added in the paint, so the prepared product avoids blocking and skinning phenomena, is easy to stir uniformly and short in drying time, is not adhered to tyres and has the characteristics of relative stability of color fastness, high paint bonding strength, high antiskid performance, wear resistance and the like.

Description

technical field [0001] The invention relates to a preparation method of a hot-melt type quick-drying colored pavement anti-skid paint. Background technique [0002] At present, the existing colored anti-skid coatings in China are mainly developed by introducing and absorbing the material technology and production technology of foreign developed countries in recent years. Therefore, there is still a lack of mature technology and construction experience in the production and application of colored anti-skid coatings. , there are defects such as unstable anti-skid performance, high construction conditions, poor chromaticity performance, poor wear resistance of the coating, and low-temperature cracking. It is not suitable for places with strict requirements on the road surface. Therefore, a more stable performance and simpler process is urgently needed , more colorful pavement non-slip coatings.
