Food-grade hose and preparation method thereof

Abstract

The invention relates to a food-grade hose which comprises a hose body; the hose body is prepared from a plastic composite material, and the plastic composite material is composed of the following components in parts by mass: 24-30 parts of resin powder, 9.58-13.5 parts of a plasticizer DOTP, 2.24-3.58 parts of calcium carbonate, 0.191-0.287 part of processing aid, 0.31-0.43 part of a stabilizer,0.04-0.07 part of toner and 0.34-0.57 part of an antibacterial agent. The food-grade hose has the advantages that the hardness and toughness of the whole material are adjusted by the plasticizer DOTP,and the hardness and toughness of the whole plastic composite material are improved, so that the prepared pipe body has high stability, durability and corrosion resistance, is less influenced by environmental temperature change, can effectively prevent harmful substances in the pipe body from being separated out in the use process, so as to reduce the harm to human body caused in the process of use and meet the requirements of environmental protection. In addition, the invention further discloses a preparation method of the food-grade hose, wherein the preparation method is used for preparingthe food-grade hose.

Description

technical field [0001] The invention relates to the technical field of hoses, in particular to a food-grade hose and a preparation method thereof. Background technique [0002] The hose is used as a pipeline for conveying medium water in the shower equipment. The existing hoses are all made of plastic materials. With the improvement of people's living standards, people pay more and more attention to their own health and environmental protection requirements. During the use of the tube, because the pipeline needs to transport the medium including hot water, the hot water is easy to heat the hose, and because the existing hose is not stable, it is easy to precipitate harmful substances, and shower on the human body together with the transmission medium, so , the existing hose is susceptible to harmful substances precipitated by the influence of temperature during use, and causes damage to the human body, and the use effect is poor.
