Abstract

The invention discloses a polyaspartic ester urea adhesive and a construction technology thereof. The adhesive comprises a main agent and a curing agent in an equivalence ratio being 1:(0.9-1.1), and the main agent is prepared from 80-90 parts by weight of polyaspartic ester resin, 2-5 parts by weight of an oxazolidine absorbent, 8-12 parts by weight of a molecular sieve, 0.1-0.5 parts by weight of a defoaming agent and 0.1-0.5 parts by weight of a base material wetting agent. The adhesive contains no toxic substances such as free TDI (toluene diisocyanate) and the like, contains no organic solvents, phthalate plasticizers and heavy metal, belongs to a solvent-free system, is environmentally friendly, non-toxic and harmless, further has good physical performance and is good in weather fastness, high in tensile strength and elongation at break, good in rebound resilience and not prone to discoloration, construction is easy, operability and physical performance of the adhesive are equivalent to those of a conventional polyurethane adhesive, and excellent environment-friendly safety and physical characteristics are integrated. The technological process of preparation is simple, conditions are mild, construction performance is good, coating is easy, and therefore, the adhesive is suitable for industrial batch production.

Description

technical field [0001] The invention belongs to the technical field of adhesive production, and in particular relates to a polyaspartate urea adhesive used for a water-permeable plastic runway and a construction process thereof. Background technique [0002] With the improvement of people's living standards, leisure sports are becoming more and more popular. The plastic runway is widely used because of its good flatness, moderate hardness and elasticity, which is conducive to the speed and technology of athletes, and can also reduce the rate of falls. It is used in various schools and stadiums, national fitness paths, playground road pavement, indoor and outdoor running tracks, stadiums, parks, residential areas and other activity venues. [0003] The plastic runway is generally paved with synthetic materials. The main production method is to use one-component moisture-cured polyurethane glue mixed with EPDM particles to form an elastic layer with a thickness of about 10mm, ...
