Production equipment and production process of internal spraying liquid

Abstract

The invention relates to the field of spraying agents, and particularly discloses production equipment of internal spraying liquid. The production equipment comprises a mixing kettle, a stirring device is arranged in the mixing kettle, a liquid feeding hole is formed in the top end of the mixing kettle, a feeding pipe is fixedly connected to a position, close to the liquid feeding hole, in the mixing kettle, and the feeding pipe is arranged at the upper part in the mixing kettle; the feeding pipe is annularly arranged at the upper end of the mixing kettle, a plurality of discharging holes are evenly formed in the lower side of the feeding pipe, a solid feeding port is formed in the top end of the mixing kettle, a discharging pipe penetrates through the bottom end of the mixing kettle, and a temperature control device is arranged on the outer wall of the mixing kettle. Liquid raw materials are uniformly discharged through the discharging holes in the feeding pipe, solid powder is fed through the solid feeding opening, and the mixing uniformity and the product quality are improved. The produced internal spraying liquid is uniform in texture, does not generate precipitates, does not need to be diluted, is directly sprayed on the surface of a green tire, is quick to dry, is easy to control in a spraying mode, and can ensure that the capsule and the green tire have good slippage performance and demolding performance after vulcanization.

Description

technical field [0001] The present application relates to the field of spraying agents, in particular to a production equipment and production process of internal spraying liquid. Background technique [0002] The internal spraying liquid is mainly used to spray on the inner surface of the tire, the main purpose is to prevent the adhesion of the tire during vulcanization and play an isolation role. [0003] Related technologies can refer to the Chinese application with application publication number CN108485515A, which discloses a kind of tire inner spraying agent and its preparation method. According to the parts by mass, it includes the following components: 8-12 parts of carbon black, tackifier 5-9 parts, silicone oil emulsion 220-260 parts, polyethylene glycol 80-120 parts, talcum powder 800-1100 parts, anionic surfactant 60-80 parts, deionized 750-950 parts. [0004] In view of the above-mentioned related technologies, the inventors found that in the production process...
