Problems solved by technology

However, this technology has the following two deficiencies in terms of skid resistance and impact resistance. First, the material composition does not contain an appropriate amount of activated modified materials, such as lack of compatibilizers, coupling agents, and activated compound modifiers. Such modifier materials will affect the dispersion, compatibility and mechanical properties of the product, and will affect the inability of the material to effectively physically entangle with the long chain of the polymer material to form a network structure, resulting in the interfacial bonding strength of the product. Reduced skid resistance and wear resistance
Second, the material composition also lacks an appropriate amount of impact modifier, providing a foaming agent, and the foaming agent has a foaming effect, and there is no synergistic effect between the impact modifier and the foaming agent, The product has good elasticity, but poor resilience
But this technology has the following disadvantages: first, component B contains a large amount of talcum powder, which is an inorganic filler with good flow and has not been activated, but has poor dispersibility and compatibility with the composition, resulting in talcum powder The accumulation of powder makes the surface of the plastic runway smoother and the anti-skid performance deteriorates
Second, the elastic bottom layer material is composed of A component and B component. The material composition does not contain an appropriate amount of modifier materials such as compatibilizers, coupling agents, and activated compound modifiers, which will affect the dispersion of materials. properties and mechanical properties of the product, especially the elastic base material is composed of A component and B component. It will affect the compatibility of materials and the interfacial bonding strength of the product, resulting in low wear resistance, impact resistance, tensile strength and elongation at break of the product, and the overall comprehensive performance needs to be improved
