Problems solved by technology

[0002] There are two types of paving materials for existing advanced sports venues (such as tennis courts, basketball courts, badminton courts, table tennis courts, and polyurethane runway surfaces): one is rigid materials, represented by acrylic resin (acrylic), and its price Low, scrub resistance, but poor toughness, easy to peel, easy to peel off; another type of elastic material is polyurethane paving material, which has the advantages of good elasticity, wear resistance, oil resistance, aging resistance, beautiful color, etc., but low construction efficiency and toxicity Big, easy to foam, pollute the environment

Embodiment Construction

[0016] Raw material name

[0017] Its processing and production process is to pour all the materials into the dispersion tank according to the proportion (remove the color paste part), disperse the materials evenly with a disperser, add the color paste and continue to disperse until uniform, then it can be discharged and packaged. The products prepared in the above examples have good elasticity, and are non-slip, wear-resistant, seamless, aging-resistant, environmentally friendly, fast in construction speed, and less affected by environmental factors. One of the notable features is that they can be sprayed to obtain self-contained particles with uniform particles. Non-slip rough surface, which is unmatched by traditional hand pouring methods. The measured technical parameters are: solid content 100%, gel time 10 seconds, tensile strength 10MPa, elongation at break 350%, tear strength 30KN / m, hardness, Shao A80-90, adhesion 5.5MPa, no Water permeability 0.3MPa / 30min...

Abstract

The invention relates to a polyurea elastic body playground earth material, which is constituted of component A and component B of equal weight ratio. The component A is isocyanate, component B includes raw materials (by weight ratio of component B) of: amido end-sealing epoxy alkane compound of 47-65%, diethyl toluenediamine of 5-8%, dimethylthio tolylene diamine of 7-9%, propylene carbonate of 3-5%, N,N'-dialkyldiamine of 4-7%, N,N'-dialkylmethanediamine of 5-8%, organic boron-moisten soil of 4-7%, and titanium dioxide of 6-9%. Advantages of the prepared product are good elasticity, anti-skid, abrasion-proof, no joint, aging resistant, environmental protection, construction speed is fast, environmental influence is less, and one of distinctive features is that self-antiskid rough surface with uniform grain is obtained by spraying.

Description

technical field [0001] The invention relates to the field of polymer chemical materials used in sports grounds, in particular to a polyurea elastomer sports ground ground material. Background technique [0002] There are two types of paving materials for existing advanced sports venues (such as tennis courts, basketball courts, badminton courts, table tennis courts, and polyurethane runway surfaces): one is rigid materials, represented by acrylic resin (acrylic), and its price Low, scrub resistance, but poor toughness, easy to peel, easy to peel off; another type of elastic material is polyurethane paving material, which has the advantages of good elasticity, wear resistance, oil resistance, aging resistance, beautiful color, etc., but low construction efficiency and toxicity Large, easy to foam and pollute the environment. Contents of the invention [0003] The purpose of the present invention is to provide a polyurea elastomer sports ground material with reasonable mate...
