FPU (flexible polyurethane) Intermediate and preparation method thereof, and plastic runway prepared with FPU intermediate and preparation method thereof

Abstract

The invention discloses an oxygen-anion-releasing FPU (flexible polyurethane) intermediate for preparation of plastic runways and a preparation method thereof, and a plastic runway prepared with the FPU intermediate and a preparation method thereof. The FPU intermediate is composed of polyether polyol, fluorite powder, volcanic powder, Liu Huan Shi (a type of sedimentary rock), Maifan stone, zinc oxide, a plasticizer, a UV (ultraviolet) antioxidant, an inorganic pigment and a chain extender. The plastic runway prepared with the FPU intermediate is prepared by: adding the FPU intermediate and hardener additive prepared in a reactor into a main agent, stirring with a high-speed disperser, and spreading on an asphalt-cement foundation; the plastic runway prepared with the FPU intermediate is capable of releasing oxygen anions good for human health for a long time, significantly enhancing blood circulation, promoting metabolism, improving immunity and giving physical and mental relief, and is also capable of absorbing harmful toxic materials from polyurethane chemical reactions, thereby providing an environment-friendly health environment for fitness enthusiasts.

Description

A kind of FPU intermediate and preparation method thereof, the plastic runway prepared by utilizing FPU intermediate and preparation method thereof technical field The invention relates to an FPU intermediate used for preparing a plastic runway and a preparation method thereof, a plastic runway prepared by using the FPU intermediate and a preparation method thereof, and belongs to the technical field of polyurethane materials. Background technique At present, the plastic track on the market can be roughly divided into two categories: polyurethane cast-in-place and prefabricated rubber coils. The prefabricated type mainly uses rubber and other raw materials. It is an environmentally friendly product, but because of its high cost, it is not popular in China; polyurethane accounts for 95% of the current domestic market, but polyurethane plastic track is generally TDI type, and its glue composition is The prepolymer formed by the reaction of polyether and TDI, if the reaction ...

Problems solved by technology

The prefabricated type mainly uses rubber and other raw materials. It is an environmentally friendly product, but because of its high cost, it is not popular in China; polyurethane accounts for 95% of the current domestic market, but polyurethane plastic track is generally TDI type, and its glue composition is The prepolymer formed by the reaction of polyether and TDI, if the reaction is insufficient, there will be free TDI. TDI is listed as a chemical substance with high occupational hazards by the country. It is a toxic carcinogen and is irritating to the eyes, respiratory tract and skin. Free TDI, some plasticizers used in polyurethane glue, such as short-chain chlorinated paraffin, will decompose chlorides such as volatile hydrogen chloride gas when exposed to sunlight, and solvents will be used in the process of on-site pouring. These solvents are generally toxic organic substances. Solvents, such as toluene, xylene, also produce pungent odorous gases that irritate the mucous membranes of the mouth and nose

When people are exercising, their breathing is deeper, blood circulation is accelerated, it is easier to inhale toxic and harmful gases into the body, and circulate to the whole body, which is even more harmful to the body
