Problems solved by technology

[0008] At the same time, the polyurethane plastic runway pavement material is an oily system. The existence of moisture will seriously affect the curing performance of polyurethane and the performance of the current runway. It requires high moisture and humidity in the environment during the laying process: concrete or asphalt base surface There should be no water; the humidity of the environment should not be too high, etc. The construction conditions are relatively harsh, which also affects the construction efficiency

Abstract

The invention relates to a novel environment-friendly water-based plastic track, which comprises three layers of structures such as a base surface layer, a plastic elastic layer and an antiskid surface layer, wherein the base surface layer is provided with a concrete or asphalt structure; the plastic elastic layer is formed by fully stirring cement, a water-based polymer emulsion, black waste rubber particles of which the particle size is 3 mm, water and an aid, paving the mixture on the base surface layer and solidifying the mixture at the normal temperature of -50 DEG C, and reaches the required thickness; and the antiskid surface layer is formed by fully stirring white cement, a water-based polymer emulsion, water, pigment and an aid to obtain a slurry, paving the slurry on the plastic elastic layer, spraying 30 to 40 mass parts of colorized EPDM particles of which the particle size is 2 to 4 mm, and performing solidification under the condition that the temperature is between the normal temperature and 50 DEG C. The novel environment-friendly water-based plastic track adopts building water-based polymer emulsion modified cement as a binding agent, is nontoxic and environment-friendly, can be used for construction in a moist environment with water, has a low cost, is simple and convenient to operate, is ventilate and hydro-ceramic, has high physical properties, and does not drop particles, and all properties of the novel environment-friendly water-based plastic track reach national standards.

Description

technical field [0001] The invention relates to a plastic runway, in particular to a novel environment-friendly water-based plastic runway. Background technique [0002] At present, most domestic plastic runways use one-component or two-component polyurethane (PU) materials, which belong to the TDI-MOCA-heavy metal ion catalyst system. There will be free TDI and heavy metal ions (mercury, lead, etc.) in the runway. Substances and volatile organic solvents (benzene, toluene, etc.) used in the laying process. [0003] Free TDI (toluene diisocyanate) exceeding 0.5% will cause harm to the human body, mainly sensitization and irritation, prone to eye pain, tearing, conjunctival hyperemia, cough, chest tightness, shortness of breath, asthma, red papules, maculopapules, contact allergies sexual symptoms. [0004] Heavy metal ions cannot be biodegraded, on the contrary, they can be enriched hundreds of times under the biomagnification of the food chain, and finally enter the human...
