Self-crosslinking adhesive. Screen Printed Flags Molecules containing the polymer chains crosslinked groups, in order to improve the fastness of color in the paste, added in small amounts outside the crosslinking agent can increase the crosslinking depth. 106 screen adhesive 8105 adhesive.
b) The dispersion in water form the binder is divided into:
The water-dispersible adhesive. Conjunctiva fast, Custom Car Window Flags do not have the high-temperature bake bake. F-type adhesive such as Akelaming.
Oil / water based adhesives. Easy to spell color, printed on pulp preparation do not have high-speed stirring, the screen is easy to clean. Such as the Dongfeng-brand adhesives, with
Water / oil binder. Clear outline of , print special fine patterns, permeability, and feel, the pattern of poor wear resistance, flammable, printed on pulp washing to use organic solvents, has been rarely used.
Ingredients ① adhesive. Pigment binder performance mainly depends on the structure of the adhesive composition and proportion and making. Natural polymer material of the adhesive has been gradually reduced, Screen Printed Flags now only as an auxiliary film-forming agent, such as chitin, natural rubber and so on. Custom Motorcycle Flags The adhesive film-forming polymers, generally by a variety of organic compounds copolymerized, with the role of each other to become the superior performance of pigment binder. Used as an adhesive synthetic polymer material can be divided into three categories.
The first is a synthetic rubber latex, Screen Printed Flags such as styrene-butadiene rubber latex and neoprene. It's a good film flexibility, wear, soft to the touch, but heat and light performance is poor. Synthetic rubber is now widely used for adhesives.
The second category is the acrylic acid esters such as methyl acrylate, ethyl, butyl, octyl, etc.. Monomers generated polymer adhesive with a transparent, heat resistance, light fastness characteristics, but dry-cleaning, abrasion resistance and elasticity somewhat less. The octyl feel the softest, followed by n-butyl, methyl ester is hard. Their film is soft but sticky in order to improve its performance, often with two or more monomers copolymerized. Acrylonitrile copolymer, can improve flexibility, abrasion resistance and resistance to dry cleaning, but feel harden and reduce the stability of the electrolyte; and styrene copolymer, the car rub abundance to improve resistance to dry cleaning and decreased elasticity, feel harden; with vinyl chloride enrichment, friction, as early as washing and dry cleaning fastness to enhance heat and light performance down the paper, feel stiff. Acrylate copolymer adhesive is widely used in countries around the world.
The third category is vinyl acetate copolymer, vinyl acetate, polyvinyl butyral and maleic acid, acrylic acid, crotonic acid copolymer. Due to poor flexibility, feel, soap, and dry cleaning fastness of vinyl acetate, Checkered Flags For Sale by copolymerization of an improvement, but also compared with other adhesives, it seldom use.
At present, most of the commonly used adhesives at home and abroad is the high temperature type chosen monomer are summarized as follows: Custom Car Mirror Flags
