Abstract

The invention discloses an elastic layer of a plastic floor, and the elastic layer is prepared from the following raw materials: a first component raw material and a second component raw material, wherein the first component raw material is composed of 850-950 kg of polyether polyol 240, 250-350 kg of polyether polyol 330, 2100-2500 kg of talc, 14-18 kg of color paste and 220-240 kg of toluene; and the second component raw material is composed of 0.484 kg of diphenyl dichlorosilane, 100-110 kg of methylene diphenyl 4,4'-diisocyanate (MDI), 0.717 kg of dibutyltin dilaurate and 22 kg of white carbon black. The processing steps comprise: feeding the first component raw material into a reaction tank, stirring, heating to 130 DEG C for dewatering; insulating for 1 hour; and firstly adding diphenyl dichlorosilane at the temperature of 93 DEG C, adding MDI at the temperature of 90 DEG C, adding dibutyltin dilaurate at the temperature below 90 DEG C, insulating for 3.5 hours at the temperature of 85-90 DEG C, cooling to 50 DEG C and discharging. The elastic layer disclosed by the invention is green, environmentally friendly, nontoxic and harmless, so that the plastic floor has appropriate hardness and elasticity as well as stable performance.

Description

technical field [0001] The invention relates to a plastic floor elastic layer Background technique [0002] Plastic flooring has a certain degree of elasticity, anti-ultraviolet and aging resistance, and is internationally recognized as the best sports ground material. [0003] For example, the advantages of plastic track are: [0004] All-weather use: It can maintain a high level of quality in any season and temperature difference, and can be used immediately after rain, increasing the utilization time and improving the site utilization rate. [0005] Elasticity: It has moderate elasticity and rebound force, which can reduce physical consumption and improve competition performance. [0006] Impact absorption: Appropriately absorb the impact of feet, reduce sports injuries, and are suitable for long-term practice and competition. [0007] Weather resistance: it will not fade, powder or soften due to pollution from ultraviolet rays, ozone, and acid rain, and it can be main...
