Problems solved by technology

[0004] However, the volatilization of gasoline will inevitably cause personal injury and environmental pollution, and it is also prone to fire
In addition, cellophane is used as the base. During the vulcanization process, although the color patterns on the base can be printed on rubber products, the melting point of cellophane or other release films is generally around 180 ° C, which is higher than the vulcanization of rubber products. temperature (140~160°C), so during the thermal transfer printing process, every time a transfer film is pasted, a piece of base paper will fall off after vulcanization. The base paper is light and easy to fly and is not degradable, which will cause environmental pollution. Fine debris or dust can also be inhaled into the lungs, endangering health

Abstract

The invention discloses a transfer membrane specially used for a rubber based on a vulcanization process. The transfer membrane comprises a substrate and a printing ink layer printed on the substrate, wherein a melting temperature of the substrate is not higher than a vulcanizing temperature in the vulcanization process, and the material of the substrate can be dissolved with the rubber under the vulcanizing temperature. The invention also provides a vulcanizing transfer printing method for a rubber product, and the method comprises the following steps: sticking the transfer membrane specially used for the rubber provided by the invention on the surface of a semi-finished rubber product, and then vulcanizing for 1.5-8 minutes under the conditions of a temperature at 140-160 DEG C and a pressure at 6-11kg / cm<2>, thereby acquiring a rubber product with a transfer printed pattern. Under the condition of using the transfer membrane provided by the invention, a process of coating a solvent is omitted. Besides, the substrate is made of a material with a vulcanizing point being consistent with or slightly lower than the vulcanizing point of rubber; and after being vulcanized, the substrate is free from being removed, thereby the secondary pollution caused by the substrate is avoided.

Description

technical field [0001] The invention relates to a thermal transfer film used for printing trademarks or other characters and patterns on the surface of rubber products. Background technique [0002] The transfer film used in the popular rubber products in the market is basically based on cellophane or other high temperature resistant release film (printing carrier film). For example, Chinese invention patent application 200510095925.X discloses a The transfer film of rubber products is made of a release film as a printing carrier film, using a rubber resin system gravure ink, and is manufactured by gravure printing. It is applied to rubber rain boots, rubber tires, triangle belts, and balloons by first transferring and then vulcanizing. Transfer decals on the surface of rubber products. [0003] When performing thermal transfer printing, it is necessary to use 120# solvent gasoline as a solvent and apply it between the surface of the rubber semi-finished product (unvulcaniz...
