Abstract
The invention relates to a food-grade hose with high and low temperature and water pressure resistance and a preparation method of the food-grade hose. The food-grade hose comprises a hose main body,a steel wire framework and fixed ports, the steel wire framework is arranged in the hose main body, the fixed ports are connected with the two ends of the hose main body, and the fixed ports are fused, bonded and fixed to the two ends of the hose main body and the steel wire framework through the injection molding process. The hose has the characteristics of hydrolysis resistance, friction resistance, -40 DEG C low temperature resistance, 70 DEG C high temperature resistance and 7 kg water pressure resistance, a No. 18 (about 1.2 mm) 304 stainless steel wire framework is embedded in the hose,the usability and convenient performance are good, and the storage is convenient; and a thermoplastic polyurethane elastomer material with the performance of processing a PU hose is firstly produced,then coats the steel wire framework by high temperature extrusion after material modification, the process is scientific and reasonable, economic benefits are achieved, and the energy consumption andcost are appropriate.
Description
technical field [0001] The invention relates to the field of water delivery hoses, in particular to a food-grade hose with high and low temperature resistance and water pressure resistance and a preparation method thereof. Background technique [0002] Energy saving and environmental protection are two major concerns in the world today. Therefore, high-efficiency, energy-saving, new and green environmental protection products have become one of the key research directions of scientists from all over the world. Thermoplastic polyurethane elastomer material, as a green and environmentally friendly new technological material, has been widely used in clothing, shoes, medical consumables and other fields. Thermoplastic polyurethane elastomer PU hose is a green, high-energy and durable special hose for transporting drinking water , has been applied in aerospace high-speed train and other fields. Commonly used water delivery hoses are ordinary rubber hoses, which can crack and red...
