Problems solved by technology

These organic solvents, catalysts and free isocyanates, etc., cause serious waste of resources and environmental pollution
[0003]1. During on-site construction, 14,000 tons / year of volatile toxic aromatic solvents and a small amount of free isocyanate volatilized into the air, damaging the health of construction workers. health, pollution
[0004]2. The volatilization of aromatic solvents is a long and long-lasting process, which can damage the health of users for a long time
[0005]3. Traditional solvent-based polyurethane paving materials need to use 3-5% catalysts containing heavy metal elements, such as organic Pb / Hg or Pb / Zn composite catalysts, 0.13 million Catalysts containing heavy metal elements per year will cause water and soil pollution in the surrounding areas of sports venues
[0006]4. Benzene non-film-forming solvents increase the cost of raw materials by 20%, and 14,000 tons of solvents are volatilized into the atmosphere every year, wasting oil resources

preparation example Construction

[0018] A preparation method of a water-based polyurethane elastomer applied to a sports field, comprising the following steps:

[0019] 1) Add wetting and dispersing agent, anti-settling agent, defoaming agent, anti-mildew agent, leveling agent, matting agent and pH adjusting agent to 5-10 mass parts of water-based polyurethane resin, and disperse evenly;

[0020] 2) Add the remaining water-based polyurethane resin and stir evenly;

[0021] 3) Add color paste and stir well;

[0022] 4) Add filler and stir well;

[0023] 5) Add elastic rubber powder and stir well;

[0024] 6) Add thickener and stir well;

[0025] 7) Filter and package.

[0026] In the construction and application, for the one-component formula that does not contain the curing agent, it can be directly sprayed for construction. For the two-component formula containing the curing agent, in the construction and application, after the other raw materials are prepared according to the above steps, then follow th...

Abstract

The invention discloses a water-based polyurethane elastomer applied to a sports ground, which includes the following raw materials: by weight parts, 50 to 80 parts of water-based polyurethane resin, 3 to 15 parts of water-based color paste, 1 to 25 parts of inorganic filler, 10 to 60 parts of elastic rubber powder, 1 to 10 parts of auxiliaries and 0 to 10 parts of hardener. The water-based polyurethane elastomer applied to the sports ground has excellent mechanical performance, drying time therefor can meet the construction requirement and the preparation method and the process thereof are environment-friendly.

Description

technical field [0001] The invention relates to a water-based polyurethane elastomer used in sports fields. Background technique [0002] The widely used polyurethane paving materials for sports venues are still traditional solvent-based two-component polyurethane materials, which usually require aromatic chemicals such as toluene and xylene as solvents and construction thinners. The amount of solvents and thinners accounts for about 20-25% of the total weight of the loaded material. During the mixing process of components A and B, it is also necessary to add 3% of a curing reaction catalyst containing heavy metal elements. These organic solvents, catalysts and free isocyanates, etc., cause serious waste of resources and environmental pollution. [0003] 1. During the on-site construction process, 14,000 tons / year of volatile toxic aromatic solvents and a small amount of free isocyanate volatilize into the air, damaging the health of construction workers and polluting the ...
