Problems solved by technology

At present, the adhesives used include formaldehyde condensates, water-based adhesives, solvent-based adhesives, hot-melt adhesives, reactive adhesives, and other types of adhesives. Silicone anti-sticking agents have lower surface energy and better Anti-adhesive effect is widely used at present, but according to the principle of similar compatibility, silicone anti-adhesive agents will stick to rolls in the application of silicone adhesives.

example 1

[0036] N 2 Under the atmosphere, add solvent, non-fluorine monomer and fluorine-containing monomer, heat up to 55 ° C, after the monomer is completely dissolved, add 0.8wt% initiator solution of the total monomer mass dropwise, the mass concentration of the initiator is 20wt% , the dropping time is 8 hours, after the dropping, the temperature is raised to 95°C, the reaction is continued for 4 hours, and cooled to room temperature to obtain a uniform fluorine-containing acrylate copolymer release agent solution.

[0037]The obtained fluorine-containing acrylate copolymer anti-adhesive agent solution is diluted with the selected polymerization solvent to a solution with a solid content of 5%, and is made into a film according to the method of GB / T 1729-1979, dried at room temperature for 12 hours, and then Dry in an oven at 80°C for 2 hours to obtain a fluorine-containing acrylate copolymer anti-adhesive film.

example 2

[0051] N 2 Under the atmosphere, add solvent and non-fluorine monomer, heat up to 55 ℃, after the monomer is completely dissolved, add dropwise 0.8wt% initiator solution of the total monomer mass, the quality of the initiator accounts for 20wt% of the total mass of the solution. Add fluorine-containing monomer when the initiator solution is added dropwise for 3 hours. The total dropping time is 8 hours. After the initiator is dropped, the temperature is raised to 95°C, and the reaction is continued for 4 hours, and cooled to room temperature to obtain a uniform fluorine-containing acrylate copolymer anti-sticking Agent solution, polymerization monomer, ratio and film-making method thereof are identical with example 1.

example 3

[0053] The method for preparing the fluorine-containing acrylate copolymer release agent solution in this example is the same as Example 1, wherein the difference from Example 1 is that the content of the fluorine-containing monomer in this example is 20wt%, and the content of butyl acrylate is 53wt%. Polymerization monomer, ratio and film-making method thereof are identical with example 1.

Abstract

Production of fluoride acrylate multi-polymer adhesion preventive agent is carried out by adding into solvent, non-fluoride monomer and fluoride monomer under existence of inert gas, raising temperature to 40-95degree, dissolving for monomers, dripping into initiator solution for 2-10hrs, heating to 60-110degree, reacting for 1-5hrs, and cooling to room temperature to obtain the final product. Ithas excellent water-proof and anti-solvent performances and alkali resistance and low stripping property.

Description

technical field [0001] The invention relates to a preparation method of a fluorine-containing acrylate copolymer anti-sticking agent. The prepared anti-sticking agent can be applied to the anti-sticking and isolation layers of solvent-based adhesives, hot-melt adhesives, and reactive adhesives, especially for organic silicon Adhesive-like release and release materials. Background technique [0002] Adhesives are widely used in packaging and binding, office supplies, labels, trademarks, etc., and need to be added between self-adhesive label paper and self-adhesive decorative film bottom layer, paper-based or film-based self-adhesive tape back, and laminated products The corresponding anti-sticking agent plays an isolation role, and the quality of the anti-sticking effect directly affects the application of the adhesive. At present, the adhesives used include formaldehyde condensates, water-based adhesives, solvent-based adhesives, hot-melt adhesives, reactive adhesives, and ...
