Problems solved by technology

[0002] The soil has a certain compressive and shear strength, but its tensile strength is very low. In order to increase the tensile strength of the soil, it is usually necessary to add or lay reinforcement materials in the soil to form a reinforced soil, which can be different degrees. To improve the strength and deformation of the soil, at present, the reinforcing material of the prior art is polyester fiber, and the polyester fiber is woven into a grid, and the polyester fiber grid has disadvantages such as flammability, poor wear resistance, and poor corrosion resistance. , therefore, it is necessary to coat a layer of wear-resistant, flame-retardant and corrosion-resistant coating on its surface in order to protect it.
[0003] The coating materials in the prior art are generally asphalt paints, which can easily cause environmental pollution during the production process of the asphalt paints in the prior art, and the production operations are cumbersome, the product cost is high, the performance of the product is unstable, and the tensile strength is low. promoted its use

Abstract

The invention relates to an emulsified asphalt paint special for a warp-knitted polyester geogrid and a preparation method. The emulsified asphalt paint is characterized by comprising compositions by mass percent: 40-55% of asphalt, 2.5-3.5% of nitrile rubber buna, 0.08-0.15% of stabilizer, 0.5-0.9% of emulsifier, 30-50% of deionized water, and 4-8% of flame retardant. The emulsified asphalt paint for the warp-knitted polyester geogrid is low in production cost, stable in product performances, high in the tensile strength of products, the preparation method for production is simple, and the product is conveniently used.

Description

technical field [0001] The invention belongs to the technical field of coatings, and more specifically relates to emulsified asphalt coatings for warp-knitted polyester grids and a preparation method thereof. Background technique [0002] The soil has a certain compressive and shear strength, but its tensile strength is very low. In order to increase the tensile strength of the soil, it is usually necessary to add or lay reinforcement materials in the soil to form a reinforced soil, which can be different degrees. To improve the strength and deformation of the soil, at present, the reinforcing material of the prior art is polyester fiber, and the polyester fiber is woven into a grid, and the polyester fiber grid has disadvantages such as flammability, poor wear resistance, and poor corrosion resistance. , Therefore, it is necessary to coat a layer of wear-resistant, flame-retardant, and corrosion-resistant coating on its surface in order to play a protective role.
