Problems solved by technology

[0003] At present, the thermal transfer silicone on the market is unstable when used, and cannot be directly transferred to the hot melt adhesive, and a layer of bridging agent is added in the middle, which is inconvenient for workers to operate; secondly, when the thickness is increased by multiple printings, the base silicone can not Fully cured, the product is prone to delamination, and the silicone label transferred to the garment is also easy to peel off when washed

Abstract

The invention relates to silica gel, in particular to thermal transfer silica gel and a preparation method thereof. The thermal transfer printing silica gel comprises a component A and a component B. The component A comprises a basic sizing material, vinyl silicone oil, MQ resin and a Karst catalyst, and the component B comprises hydrogen-containing silicone oil and an inhibitor. According to the thermal transfer printing silica gel and the preparation method thereof, the adhesion of a silica gel system is improved, the prepared thermal transfer printing silica gel and a hot melt adhesive have good adhesion force, during transfer printing, an intermediate layer is not needed, the hot melt adhesive and the silica gel can be directly bonded, the flowability and thixotropy of a sizing material system are reduced, and construction operation is facilitated.

Description

technical field [0001] The invention relates to silica gel, in particular to thermal transfer printing silica gel and a preparation method thereof. Background technique [0002] With the development of the world's industrial economy and the improvement of people's living standards, people are more and more particular about clothing and more and more beautiful, and the trademark on the clothing adopts the method of heat transfer printing, and the finished transfer label is directly passed through The transfer printing machine is printed on the clothing, which is not only beautiful and durable, but also prevents a large number of defective products directly printed on the clothing by silk screen printing. The method of heat transfer printing can be used to make the trademark label first. After the trademark is completed, it is directly sent to the clothing company for transfer to On clothing, the cost of back and forth transportation of clothing is reduced, and the pass rate o...
