Problems solved by technology

[0004] The purpose of this invention is to provide a polyester resin adhesive for ultra-thin stretch-resistant polyester tape, which solves the problem of poor heat resistance, poor bonding strength and oxidation resistance of existing polyester resin adhesives in the prior art. It is not good, so it leads to problems such as many defective products, low output, and high wood. At the same time, because the cohesive force of the polyester resin adhesive is unstable, it is easily affected by the temperature and humidity changes in the working environment in the morning and evening, which leads to In addition to the problem that the bonding fastness cannot be guaranteed and the practicability is poor in practical applications

Embodiment 1

[0022] A polyester resin adhesive for ultra-thin stretch-resistant polyester tape, consisting of the following raw materials: 70-80 parts of polyester polyol, 5-10 parts of epoxy resin, 1-5 parts of antioxidant, adhesion promoter 1-5 parts, 1-5 parts of leveling agent, 5-10 parts of isooxyester polymer, 0-30 parts of solvent, 100 parts of polyester resin, 10-30 parts of petroleum resin, 15-25 parts of oil-soluble phenolic resin parts, 5-15 parts of talcum powder, and 0.5-1.5 parts of diphenyloctyl phosphite, and the parts are parts by mass.

[0023]

[0024]

[0025] According to the above examples, it can be seen that polyester polyol is the main resin, which is used to bond the ribbon substrate, epoxy resin can improve the heat resistance of the whole system, antioxidant can improve the oxidation resistance of the adhesive, adhesion promoter It can improve the bonding strength between the adhesive and the substrate, thus, the improved polyester resin adhesive greatly i...

Embodiment 2

[0027] Stir the polyester polyol and solvent at no higher than 80°C until the polyester polyol is completely dissolved, then cool down to below 40°C, add epoxy resin, antioxidant, adhesion promoter, leveling agent, Isooxyester polymer, polyester resin, petroleum resin, oil-soluble phenolic resin, talcum powder and diphenyloctyl phosphite, stir evenly, 77 parts of polyester polyol, 7 parts of epoxy resin, antioxidant 4 parts, 100 parts of polyester resin, 20 parts of petroleum resin, 20 parts of oil-soluble phenolic resin, 10 parts of talcum powder, 1 part of diphenyloctyl phosphite, and the parts are parts by mass.

Abstract

The invention relates to the technical field of polyester resin adhesives, in particular to a polyester resin adhesive for an ultrathin stretch-proof polyester belt, and solves the problems that in the prior art, an existing polyester resin adhesive is poor in heat resistance, oxidation resistance and bonding strength and poor in practicability in practical application. A polyester resin adhesive for an ultrathin stretch-proof polyester belt comprises 70-80 parts of polyester polyol, 5-10 parts of epoxy resin, 1-5 parts of an antioxidant, 1-5 parts of an adhesion promoter, 1-5 parts of a leveling agent, 5-10 parts of an isoxo acid ester polymer, 0-30 parts of a solvent, 100 parts of polyester resin, 10-30 parts of petroleum resin, 15-25 parts of oil-soluble phenolic resin, 5-15 parts of talcum powder, and 0.5-1.5 parts of diphenyl octyl phosphite ester. The polyester polyol is main body resin and is used for bonding a colored tape base material, the epoxy resin can improve the heat resistance of the whole system, the antioxidant can improve the oxidation resistance of the adhesive, and the adhesion promoter can improve the bonding strength of the adhesive and the base material.

Description

technical field [0001] The invention relates to the technical field of polyester resin adhesives, in particular to a polyester resin adhesive for ultra-thin stretch-resistant polyester tapes. Background technique [0002] Polyester resin adhesives are intermediates connecting two materials, mostly in the form of water agents, belonging to the category of fine chemicals, with a wide variety, mainly based on the classification methods of adhesives, physical forms, hardening methods and adherend materials. The common ones are instant glue (the common -1203 instant adhesive-ethyl cyanoacrylate strong instant adhesive is one kind), polyester resin bonding, anaerobic polyester resin adhesive, UV polyester resin adhesive (ultraviolet light curing), hot melt adhesives, pressure sensitive adhesives, latex, etc. [0003] However, due to the poor heat resistance, poor bonding strength and poor oxidation resistance of the existing polyester resin adhesives, problems such as many defect...
