Problems solved by technology

However, due to the insufficient deionization of amine-containing polymers in the coating preparation process, phenomena such as increased viscosity, microcoagulation, and agglomeration are prone to occur during paint production or storage. Poor water resistance and stain resistance, the paint film becomes soft in rain or high temperature, causing the paint film to fall off and affecting the service life of road signs

Abstract

The present invention is self-linking water thinned road mark paint and its preparation and usage. The road mark paint is storage stable and has solid content of at least 75 %, and anionic self-linking silicone propylene emulsion as main material. Specifically, it consists of anionic self-linking silicone propylene emulsion 20-50 weight portions, distilled water 1-5 weight portions, methanol 1-5 weight portions, filming assistant 1-5 weight portions, dispersant 1-3 weight portions, moistener 0.1-1 weight portions, disinfecting mildew inhibitor 0.1-0.5 weight portions, defoaming agent 0.1-0.5 weight portions, and pigment and stuffing 20-80 weight portions. It may be painted to road directly or on primer, and may be used widely for different kinds of road.

Description

technical field [0001] The invention relates to a self-crosslinking water-based road marking paint and its preparation and application method. Background technique [0002] With the development of the national economy, the total mileage of my country's highways has reached 1.25 million kilometers in the 21st century. The vigorous development of road construction has promoted the development of road marking paint. About 90% of road marking paints currently used are solvent-based paints that dry at room temperature. This type of road marking paint contains volatile organic compounds (hereinafter referred to as VOC) as high as 650g / l. In the process of making paint or drawing road signs, the volatilization of VOC will cause harm to operators and the environment; there is also a kind of hot-melt road marking paint. Although the VOC content is low and the durability is good, it needs to be heated and melted during construction. It is very difficult, and the old coating must be...
