TPU high-pressure water hose production process and full-automatic production equipment thereof

Abstract

The invention discloses a TPU high-pressure water hose production process and full-automatic production equipment thereof. The production process comprises the following steps that a, base cloth pretreatment is achieved: a low-shrinkage and high-strength base cloth roll is selected as gray cloth; water-based PU adhesive or TPU hot melt adhesive is coated on the gray cloth by using a blade coating machine, drying and rolling are achieved; b, base cloth and a TPU wear-resistant layer are bonded: tape casting is carried out on TPU by using a tape casting machine to form the TPU wear-resistant layer, the TPU wear-resistant layer is pressed into a plane, drying and rolling are achieved; c, double-sided coating is achieved: the TPU wear-resistant layer and the inner layer of the base cloth are bonded to form double surfaces; d, slitting and rolling are conducted, specifically, slitting and rolling are conducted according to the width of the product specification; and e, hot-press forming is achieved: the two ends of the base cloth are overlapped, and hot-press sealing forming is performed in a special hot press for hot-press sealing forming; and a finished product is rolled, and cooling is achieved to obtain a water hose. The TPU high-pressure water hose production process and the full-automatic production equipment thereof has the following beneficial effects that the TPU high-pressure water hose which is large in caliber, wide in application range, high in pressure resistance, light in weight, high in oil resistance, wear resistance and low-temperature resistance and finally long in service life can be provided by the TPU high-pressure water hose production process.

Description

technical field [0001] The invention relates to a TPU high-pressure hose production process and its fully automatic production equipment. Background technique [0002] The hose usually refers to a certain length of soft and coilable round or flat tubular body composed of warp and weft woven tubular fabric layers and lining or covering layers through steam vulcanization or adhesives. Due to the variety of fire hoses, their structures also have various types, but the basic structure includes five parts: fabric layer, lining, coating, covering layer and adhesive layer. The fabric layer is the skeleton material of the hose, which provides high pressure resistance and wear resistance for the hose, and is generally woven from fiber materials such as cotton, polyester and nylon. The lining is a smooth and waterproof layer with a certain strength on the inner wall of the fabric layer, which ensures the smooth transportation of water or other liquids. The materials used mainly inclu...
