Problems solved by technology

The invention is environmentally friendly, non-toxic and harmless, and makes the plastic floor have appropriate hardness and elasticity and stable performance. However, the elastic layer prepared by the invention has a bending failure load of only 834-852N after laboratory testing, and the aging performance after 360 days is low. More than 53% (bending failure load retention rate ≥ 80%), the most important thing is that the tensile strength, elongation at break, rebound value, hardness, compression recovery rate, flame retardancy can not reach or partially meet the national technology The standard requirements stipulated in GB / T14833-93 "Plastic Runway" issued by the Supervision Bureau

Abstract

The invention relates to a low-odor low-toxicity plastic floor elastic layer and a production process thereof. The low-odor low-toxicity plastic floor elastic layer is prepared from first component raw materials including 1050 kg to 1250 kg of polyether polyol 330, 300 kg to 450 kg of talcum powder, 14 kg to 18 kg of mill base and 220 kg to 240 kg of methylbenzene and second component raw materials including 0.484 kg of diphenyl dichlorosilane, 100 kg to 110 kg of MDI, 0.717 kg of dibutyltin dilaurate and 22 kg of white carbon black. The first component raw materials are put in a reaction tankto be stirred and heated to 200 DEG C, dehydration and heat preservation are carried out for 1 hour, diphenyl dichlorosilane is firstly added at the temperature of 93 DEG C, MDI is added at the temperature of 90 DEG C, dibutyltin dilaurate is added at the temperature of 85 DEG C to 90 DEG C, heat preservation is carried out for 3.5 hourse at the temperature of 85 DEG C to 90 DEG C, the temperature is reduced to 50 DEG C, discharging is carried out, and elastic layer coating is obtained. The low-odor low-toxicity plastic floor elastic layer is better in performance, not likely to be damaged, high in elasticity and suitable for being used in indoor stadiums and larger large public places.
