Problems solved by technology

The disadvantage of this method is that the product cannot be squeezed during the vulcanization process, which will easily cause the pattern pigment to flow, and the pattern needs to be dried at high temperature after printing.
The disadvantage that is more difficult to overcome is

Embodiment 1

[0026] Embodiment 1: vulcanized pattern on the surface of rubber sole

[0027]Inks were formulated with different formulations containing rubber raw material and sulfur (1%, 3%, 5%, 8%, 10% or 15%). Print inks with different ratios on the high temperature resistant paper film with the same pattern, and let it dry in time. In addition, the rubber material of the same rubber sole is prepared, and it is injected into the embryo film of the rubber sole of the same shape to make the prototype of the rubber sole. Paste the printed paper film on the same position of the prototype of the rubber sole, make rubber sole molding molds with a ratio of 1:1, 1:1.1, and 1:1.2 (prototype:mold) respectively, and paste the rubber sole with the patterned paper film The prototype is placed in a forming mold and vulcanized at 100°C, 120°C, 140°C, 160°C, 180°C and 200°C for 0.5min, 1min, 3min, 6min, 10min and 15min respectively, the mold is opened, the paper film is torn off, and the belt is obtai...

Abstract

The invention involves a rubber product surface vulcanizing pattern method, it includes the following steps: i) selecting the patterns needed vulcanizing on the rubber product, and formulating the printing oil containing rubber materials and sulfur; ii) printing the said patterns in step i) on the high temperature resistant paper film through printer, then getting pattern paper film; iii)injecting the rubber raw materials into the blank die of rubber product, preparing embryonic rubber product; iv) sticking said pattern paper film in step ii) on the needed position in embryonic rubber product; v) putting the embryonic rubber product with said pattern paper film prepared in step iv) in the product shaping die, heating and vulcanizing treatment; vi) taking the embryonic rubber product said in step v) out from shaping die, removing paper film and getting the rubber product which surface has patterns. The invention enables pattern stable, product external appearance good, die cost low, die is difficult to be polluted, it is suitable for various rubber surface patterns vulcanization.

Description

technical field [0001] The invention relates to the field of rubber products, in particular to a method for vulcanizing patterns on the surface of rubber products. Background technique [0002] Rubber products involve all aspects of human life, especially for rubber products used in people's daily life. In order to beautify people's life, various patterns are made on the surface of the product to make the product more beautiful. This is the goal that rubber product manufacturers are striving for. . The method of printing patterns on the surface of rubber products is usually vulcanized in the rubber product industry, that is, adding an appropriate amount of sulfur to the printing ink mixed with rubber, and through the action of sulfur at high temperature, the rubber and ink in rubber products The rubber in it is densely bonded, thereby fixing the pattern on the rubber product. [0003] At present, when vulcanizing various patterns and colors on the surface of rubber product...
