Problems solved by technology

However, there will be some unsolvable and inevitable problems in the printing of addition-type silica gel: (1) addition-type silica gel uses precious metal platinum as a catalyst, which makes the addition-type silica gel expensive; (2) also due to the platinum catalyst, some fabrics and oily Taiwan glue are easy to poison addition-type silica gel, such as diving fabrics and genuine leather; (3) Addition-type silica gel has poor adhesion to many textiles, such as nylon, waterproof nylon, PU, ​​genuine leather, etc., and adhesives are required As the middle layer, the price of the adhesive is often several times that of silica gel, which is even more unbearable
Therefore, the disadvantages of addition-type silicone make it difficult for silicone printing to occupy most of the market in the printing industry in the next few years

Abstract

The invention discloses a condensed type printing silica gel which is characterized by being prepared from the following components in a weight ratio of a basic silica gel to a curing agent to a color paste being 10 to 2 to 1, wherein the basic silica gel is prepared from the following components in parts by weight: 70-85 parts of hydroxyl silicone oil (107 silicone oil), 15-30 parts of fumed silica and 3-6 parts of an auxiliary A which are kneaded and rolled three times; the curing agent is prepared by mixing the following components in parts by weight: 10 parts of an alkoxy siloxane compound, 3-5 parts of a silane coupling agent and 0.1-0.5 part of a catalyst. The invention discloses a preparation method of the condensed type printing silica gel and application of the condensed type printing silica gel. The condensed type printing silica gel can be printed to common cloth such as cotton, lycra, microfibers, canvas as well as nylon, part of waterproof nylon, part of PU shell fabric and leather. The condensed type printing silica gel disclosed by the invention has the advantages of low price, poisoning resistance, no adhesive and organic tin and the like.

Description

technical field [0001] The invention relates to the technical field of condensation rubber printing, in particular to a condensation type printing silica gel, a preparation method, and an application of the condensation type printing silica gel. Background technique [0002] With the development of science and technology, people's environmental protection requirements for daily necessities and industrial products are increasing day by day, especially the environmental protection requirements for textiles that are in contact with them all the time are more urgent. People's pursuit of beauty has never changed, and various gorgeous patterns of textiles have greatly satisfied people's pursuit of beauty. Traditional textile printing is mainly the printing of ink and glue. However, in recent years, silicone printing has also emerged and gradually occupied part of the printing market. Many printing factories are actively developing silicone printing technology and business. This is...
