Embodiment 1

[0022] Get 65 parts by weight of glycerol glycidyl ether type epoxy resin, 28 parts by weight of closed type blocked isocyanate, and 6.5 parts by weight of epoxy resin dispersant, put them into the reaction kettle and stir to form polyester toughened brown silk bonding activator;

[0023] Put the polyester toughened brown silk into the prepared adhesive activator for dipping, so that the polyester toughened brown silk is covered with liquid; put the polyester toughened brown silk soaked in the adhesive activator into a heating container, Heat treatment at a temperature of 240° C. for 60 minutes to form an epoxy resin surface layer on the surface.

[0024] The above-mentioned polyester tempered brown silk treated with the adhesive activator, and then use the RFL (condensate of resorcinol, formaldehyde and latex) adhesive used in the two-bath dipping system, and then use the conventional RFL A two-bath dip was performed which gave an adhesion value of 185.3.

Embodiment 2

[0026] Get 68 parts by weight of glycerol glycidyl ether type epoxy resin, 26 parts by weight of blocked isocyanate, and 7.0 parts by weight of epoxy resin dispersant, put them into the reaction kettle and stir to form polyester toughened brown silk bonding activator.

[0027] Put the polyester toughened brown silk into the prepared adhesive activator for dipping, so that the polyester toughened brown silk is covered with liquid; put the polyester toughened brown silk soaked in the adhesive activator into a heating container, Heat treatment at a temperature of 230° C. for 40 minutes to form an epoxy resin surface layer on the surface.

[0028] The above-mentioned polyester tempered brown silk treated with the adhesive activator, and then use the RFL (condensate of resorcinol, formaldehyde and latex) adhesive used in the two-bath dipping system, and then use the conventional RFL A two-bath dip was performed which gave an adhesion value of 193.9.

Embodiment 3

[0030] Get 66 parts by weight of glycerol glycidyl ether type epoxy resin, 24 parts by weight of blocked isocyanate, and 6.6 parts by weight of epoxy resin dispersant, put them into the reaction kettle and stir to form polyester toughened brown silk bonding activator.

[0031] Put the polyester toughened brown silk into the prepared adhesive activator for dipping, so that the polyester toughened brown silk is covered with liquid; put the polyester toughened brown silk soaked in the adhesive activator into a heating container, Heat treatment at a temperature of 225° C. for 80 minutes to form an epoxy resin surface layer on the surface.

[0032] The above-mentioned polyester tempered brown silk treated with the adhesive activator, and then use the RFL (condensate of resorcinol, formaldehyde and latex) adhesive used in the two-bath dipping system, and then use the conventional RFL A two-bath dip was performed which gave an adhesion value of 190.7.

Abstract

The invention belongs to the technical field of manufacturing of polyester tempering palm fiber in a driving belt, and in particular discloses a polyester tempering palm fiber adhesion activating agent and a treatment process of the polyester tempering palm fiber. The process comprises the steps of feeding propanetriol-diglycidyl-ether type epoxy resin, enclosed isocyanate and an epoxy resin dispersing agent into a reaction kettle, and stirring to form the polyester tempering palm fiber adhesion activating agent; inserting the polyester tempering palm fiber into the adhesion activating agent and soaking to form an epoxy resin surface layer on the surface. The treated polyester tempering palm fiber is subjected to two-bath immersion by using an RFL (condensation compound of resorcinol, formaldehyde and latex) adhering agent used in a two-bath gum dipping system and using the conventional RFL again, thereby greatly improving the numerical value of the adhesive force. The problem of poor adhesion strength of the polyester tempering palm fiber and rubber is solved, so that the polyester tempering palm fiber becomes the ideal tensile body of the rubber product.

Description

technical field [0001] The invention belongs to the technical field of polyester toughened brown silk in the manufacture of transmission belts, and relates to a polyester toughened brown silk adhesive activator and a polyester toughened brown silk that can improve the surface adhesive activity of polyester toughened brown silk in the prepreg process. Silk processing technology. Background technique [0002] During the "Seventh Five-Year Plan" period in my country, the requirements for V-belt cords and polyesters were put forward, but polyester cords were not widely used until the mid-1990s. The application of polyester cords greatly improved the practical performance of V-belts. and life; however, polyester cord has the disadvantages of large high-temperature shrinkage, high dynamic heat generation, and easy relaxation. Polyester toughened brown silk is a newly developed rubber skeleton material. Compared with traditional polyester soft rope, hard rope, aramid and other skel...
