Abstract

The invention provides a preparation method of a TPU composite material for an oil storage bag. The method comprises the following steps of (1) respectively coating a binding layer in a scraping way or a rolling way on two sides of a framework layer; then, performing drying at the drying temperature being 160 to 180 DEG C for 1 to 3 minutes; (2) performing pre-drying at the temperature being 140 to 160 DEG C for 5 to 10s; then, performing extrusion casting of the first surface and the second surface at the two sides of the material obtained in the first step, wherein the extrusion casting temperature is 190 to 200 DEG C; (3) pasting the material obtained in the second step by a laminating roller; (4) heating and baking the material obtained in the third step. The method overcomes the detects in the prior art, the production and preparation process is simple; the prepared product has better oil resistant performance, water resistant performance and weather resistant performance; the oil resistant performance is ensured; meanwhile, the hydrolysis resistant performance of products is improved.

Description

technical field [0001] The invention belongs to the field of composite materials for oil bladders, and in particular relates to a preparation method of TPU composite materials for oil storage bladders. Background technique [0002] Most of the existing soft oil bladder materials on the market are still made of PVC or rubber. This material has poor weather resistance, wear resistance, high and low temperature resistance and tensile strength, and the material is not environmentally friendly. There are also a small number of TPU soft oil bladders on the market, but the peel strength and oil resistance are not satisfactory. Contents of the invention [0003] In view of this, the present invention aims to propose a preparation method of TPU composite material for oil storage bag, to overcome the deficiencies of the prior art, the production and preparation process is simple, and the prepared product has better oil resistance, water resistance and weather resistance , while ens...
