Problems solved by technology

[0008] At present, the commonly used rubber release agents mainly have three forms: powder, solid and liquid. The main components of solid and liquid release agents are fatty acid soap, which is composed of animal fat It is made by saponification, and the price is generally low, but the isolation effect is poor, and it has a great impact on the performance of the rubber compound. It can be dispersed in water only by heating. Stagnation, production efficiency drops significantly
[0009]Powder release agents are generally more complicated, mostly compound products such as silicates and metal soaps, and are modified by surfactants, early-based, and isolated from imported products The effect is good and has little effect on the properties of the rubber compound, but the price is expensive. In recent years, the release agent has been valued by many domestic scientific research institutions and manufacturers, and new products continue to appear. At present, there are many manufacturers of powder release agents. The price is relatively cheap, but the quality is uneven. No agent, and there are generally problems such as poor isolation effect, insoluble, foaming, precipitation, slow drying speed, and environmental pollution caused by flying

Abstract

Belonging to the field of chemical materials, the invention particularly relates to a water soluble rubber separant with antibacterial and mildewproof properties. The water soluble rubber separant provided by the invention comprises the following components by weight part: 1-8 of a stearic acid salt, 2-10 of a thickening agent, 1-6 of an anti-sticking agent, 1-6 of a surfactant, 2-8 of vegetable oil, 1-5 of soda ash, 1-5 of an emulsifier, and 2-6 of silicone oil. The water soluble rubber separant provided by the invention is safe, non-toxic, odourless, and harmless to the human body, has a good separation effect and small dosage, and is especially suitable for rubber products and sheet rubber. Being easy to dissolve in water, the water soluble rubber separant cannot generate precipitate due to different water quality. Tests show that, at a water temperature of 50DEG C, no precipitate is generated in 680 hours.

Description

technical field [0001] The invention belongs to the field of chemical materials, and in particular relates to a water-soluble rubber release agent with antibacterial and antifungal properties. Background technique [0002] In the production and processing of rubber products, due to its unique self-adhesiveness, processing and transportation are difficult, especially for the handling and reprocessing of mixed rubber and plasticized rubber. Therefore, before the rubber compound is finally made into a finished product, such as before handling and storing the mixed rubber, before extrusion, extrusion and hot mixing, a layer of release agent will be applied to the corresponding film to prevent the films from sticking to each other. . [0003] After the rubber material is processed by refining or banburying equipment, it is pressed and cooled, and the laminated sheets are parked on the rubber tray. The surface of the film is highly viscous and under the action of layer-by-layer ...
