Novel netlike printing adhesive formed by copolymerizing acrylate and organosilicone

Abstract

The invention discloses a novel netlike printing adhesive formed by copolymerizing acrylate and organosilicone. Polymerization monomers are selected from a vinyl monomer, an acrylate monomer, a functional monomer, organosilicone oil, an emulsifying agent and an initiator; the molecular structure of the conventional acrylate-based product is changed to synthesize the netlike printing adhesive formed by copolymerizing the acrylate and the organosilicone. The novel netlike printing adhesive has excellent performance; compared with the conventional products, the novel netlike printing adhesive hasthe advantages as follows: a printing technology and the product quality are significantly improved, the energy is saved, the cost is reduced, the printing effect is improved, and the physical styleof a product is changed; the novel netlike printing adhesive is soft and comfortable in hand feel, is similar to reactive dye printing, but has better fastness, has very good elasticity and flexibility, and can be applied to printing of elastic knitted fabrics; a film can be formed by drying at room temperature, and the color fastness is good, so that the novel netlike printing adhesive can be applied to manual printing without drying or baking equipment; compared with the existing products in the market, the novel netlike printing adhesive has the advantage as follows: the using cost thereofcan be reduced by 20-25%.

Description

technical field [0001] The invention relates to the related field of printing adhesives, in particular to a new type of screen printing adhesive formed by polymerization of acrylate silicone. Background technique [0002] Pigment printing process is simple, energy saving, no waste water discharge, complete color spectrum, convenient color matching, clear printing outline, high authenticity rate, strong reproducibility, and general light fastness, so it is widely liked by people. With the continuous development of science and technology, many new technologies and materials are applied to the pigment printing process, especially with the development of synthetic fibers and their blended fabrics, the superiority and importance of pigment printing are more prominent. Today's global pigment printing has an average share of more than 70% of the total printing market share, which is the largest proportion of all printing volumes. [0003] The large-scale application of pigment pri...

Problems solved by technology

The molecular structure of the crosslinking agent has strong active groups, which can react with hydroxyl or amino groups at about 100°C, which can improve the film-forming fastness to rubbing and greatly save energy, but the cost is high

(2) Domestic situation: In recent years, my country's pigment printing has also made great progress, but the product structure is not reasonable enough. Most of the middle and low-end products have meager profits. The ordinary T-shirts are about 105 yuan per piece in the market, while The same blank garment after printing the pattern is 8-25 yuan per piece. The quality and grade of pigment printing products depend to a large extent on the performance of pigment printing adhesives. Therefore, preparing high-performance adhesives is the key to improving pigment printing technology and quality. one of the measures

[0020] Reason 1: Labor protection of workers: At present, the printing adhesives used in my country are mainly acrylic adhesives. During the use of such adhesives, necessary conditions such as drying and baking need to be given to achieve curing and crosslinking. The purpose of the membrane

[0023] Reason 3. Disadvantages of the current use of printing adhesives: At present, the printing adhesives used in my country are mainly acrylic esters, because of their strong adhesion, good film-forming properties, good oil resistance, oxidation resistance and weather resistance , has strong adhesion to both polar and non-polar surfaces, and has the advantages of abundant raw materials, easy production, and low cost; when its water resistance, stain resistance is poor, and it becomes brittle at low temperature and becomes sticky at high temperature, the product The hand feeling is hard, and the wet rubbing fastness of printed dark-colored products is poor, which seriously affects its performance.

[0024] Reason 4. Environmental protection and energy-saving issues: currently used coating adhesives require high-temperature baking, which requires heating, which wastes resources and increases carbon emissions, which violates the requirements of my country's energy-saving emission reduction and low-carbon life

Free formaldehyde is released during use, which not only affects product quality, but also causes huge environmental pressure. Formaldehyde ranks second on the list of priority control of toxic chemicals in my country.
