Problems solved by technology

However, this invention still uses a two-component system, which requires on-site weighing of ingredients in proportion and mixing evenly. This link is very error-prone, and once a mistake is made, it will lead to serious quality problems

Embodiment 1

[0054] Environmentally friendly one-component water-cured self-knotting plastic runway material is made of the following raw materials in parts by weight: 40 parts of difunctional polyether polyol 220, 40 parts of trifunctional polyether polyol 330N, 40 parts Parts polyol benzoate, 40 parts epoxidized soybean oil, 20 parts diphenylmethane diisocyanate, 3 parts pigment, 70 parts talc, 10 parts stabilizer, 2 parts rheological agent, 1.5 parts calcium oxide, 2 parts Parts of white carbon black, 2 parts of dispersant, 2 parts of antioxidant, 70 parts of kaolin, 50 parts of butyl acetate, 15 parts of latent curing agent, 1 part of hydrolysis accelerator.

[0055] Polyether (including difunctional polyether polyol and trifunctional polyether polyol) has the functions of emulsification, wetting and viscosity adjustment. Polyol benzoate and epoxidized soybean oil are plasticizers with plasticizing effect. Diphenylmethane diisocyanate is used as a curing agent to adjust the hardness o...

Abstract

The invention relates to an environment-friendly type one-component water-cured lines-self-forming plastic track material and its preparation method. The track material contains the following raw materials, by weight, 30-50 parts of bifunctional polyether polyol, 30-50 parts of tri-functional polyether polyol, 30-50 parts of diethylene glycol dibenzoate, 30-40 parts of epoxidized soybean oil, 20-30 parts of methyl diphenylene diisocyanate, 1-5 parts of pigment, 60-80 parts of powdered steatile, 10-20 parts of a stabilizer, 1-5 parts of a rheological agent, 0.5-3 parts of calcium oxide and 1-3 parts of white carbon black. The track material is environmentally friendly, can be prepared in advance, is stored in a barrel after being prepared and is directly used at a construction site. According to the invention, the problem that bi-component materials need to be weighed and blended on site and must be uniformly stirred is minimized; three links which are most likely to get wrong during the construction process are avoided; construction process is simplified; and construction efficiency is enhanced.

Description

technical field [0001] The invention relates to the technical field of track facilities for sports venues, in particular to an environment-friendly one-component water-cured self-knotting plastic track material and a preparation method thereof. Background technique [0002] With the development of social economy, environmental protection problems are becoming more and more severe, and people have higher and higher requirements for the safety performance of sports facilities. At present, the domestic plastic track mostly adopts two-component polyurethane oily system, which belongs to (TDI+MDI)-MOCA-heavy metal ion catalyst system. There is free TDI (toluene diisocyanate) in the runway, and free TDI exceeding 0.5% will cause harm to the human body; the cross-linking agent MOCA is toxic and is a suspected carcinogen; heavy metal ions (mercury, lead, zinc) are toxic substances, Volatile organic solvents such as benzene, toluene, and xylene used in the laying process are also to...
