Problems solved by technology

However, when the surface of the silicone tube is coated according to this method, the thickness of the coated film is often uneven, the adhesion between the coated coating and the material of the silicone tube is not strong, there is stress between the film and the substrate, and it is easy to fall off, so , has not been practically applied

Abstract

The invention provides a silicone tube coating method and application. The silicone tube coating method comprises the following steps of (1) silicone tube pretreatment; (2) reliability detection of silicone tube pretreatment; (3) mounting of silicone tubes on a frame; and (4) depositing and coating. According to an embodiment of the silicone tube coating method and the application, through a gas-phase depositing mode, the effect that the surfaces of the silicone tubes are coated with compact thin films is achieved, and micro holes in the surfaces of the silicone tubes are closed, so that the surfaces of the silicone tubes are smooth and free of the holes. External smells are prevented from infiltrating into a water body after entering the micro holes of the silicone tubes, and meanwhile, the phenomenon that incompletely-vulcanized chemical substances of silicone tube materials separate out and enter the water body is inhibited, so that the peculiar smell of the water body is effectively lowered. The silicone tube coating method is applied to surface coating of the silicone tubes, has the advantages that batch production is easily achieved, raw materials are saved, and pollution is low and can be applied to production of the silicone tubes of water dispensers.

Description

technical field [0001] The invention belongs to the technical field of coating, and in particular relates to a coating method and application of a silicone tube. Background technique [0002] With the continuous improvement of people's health awareness, the requirements for the sanitation and safety performance of drinking water and its treatment equipment are also getting higher and higher. Water dispensers with a high penetration rate among many drinking water equipment have always had many problems. Among them, the peculiar smell of the water is a major problem. Generally, it is the rubber material of polysiloxane silicon material. These polysiloxanes are vulcanized at high temperature to form elastic silicone tubes suitable for water dispenser equipment. The silicone tube used for water dispenser equipment has elastic deformation ability, has an open porous structure, has strong adsorption capacity, and can absorb various substances. However, this type of silica gel ma...
