Abstract

The invention relates to a TPU / silica gel composite material. The TPU / silica gel composite material comprises a base cloth layer, a first hot melt adhesive layer, a TPU layer, a second hot melt adhesive layer and a silica gel layer which are successively stacked; and the first hot melt adhesive layer and the second hot melt adhesive layer are both TPU hot melt adhesive layers. The provided high-wear-resistance TPU / silica gel composite material is good in wear resistance, and after the high-wear-resistance TPU / silica gel composite material is ground by 1000 revolutions under the pressure of 9kPa, wear is not obvious, moreover, light scattering of the high-wear-resistance TPU / silica gel composite material is obviously higher than that of a silica gel material, and the flame retardance is good. The silica gel layer is thinned until the thickness of the silica gel layer is suitable, is matched with the hot melt adhesive layers, and firmly adheres to the TPU layer, air bubbles are avoided due to tape casting, and therefore, the material has good light scattering property on the premise of good wear resistance.

Description

technical field [0001] The invention belongs to the field of artificial leather manufacturing, and in particular relates to a high wear-resistant TPU / silica gel composite material and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy, the demand for leather products is increasing, and the grade is getting higher and higher. Automotive interior leather has been widely used in interior parts of passenger cars and transport vehicles. The best choice for automotive interior leather is genuine leather, but the production process of genuine leather seriously pollutes the environment, and the content of heavy metals tends to exceed the standard. It is accepted by cars; and people are paying more and more attention to environmental protection. Today, when environmental protection, energy saving and sustainable development are advocated, people have also begun to develop imitation leather fabrics to replace animal leather,...
