Embodiment 1

[0028] The mass parts of each component of a high-strength adhesive formulation are as follows

[0029] 1) 76 parts of natural 3L rubber,

[0030] 2) The accelerator is a mixture of zinc oxide, PEG4000, antioxidant 1076, accelerator DM, accelerator D, CBS accelerator, 4010 anti-aging agent and MB anti-aging agent 4.5 parts

[0031] 3) 16 parts of white smoke, talcum powder and graphite are selected as filler

[0032] 4) 2 parts of sulfur is selected as vulcanizing agent

[0033] 5) 1.5 parts of RX80 tackifier is used as tackifier

[0034] When preparing:

[0035] 1) According to the formula ratio, pass the natural 3L rubber through an open mill for 15-25 minutes to mix mature rubber;

[0036] 2) Add accelerators, fillers, and tackifiers to the smelted cooked rubber in proportion and mix them evenly through an open mill. The temperature is adjusted between 30 and 35 degrees for 15 minutes to make it into a gel;

[0037] 3). Finally, add vulcanizing agent during ...

Abstract

The invention relates to the technical field of adhesives, in particular to an adhesive used in the field of diving and boat supplies. The high-strength adhesive comprises the following constituents in percentage by mass: 60-85 percent of natural 3L rubber, 5-9 percent of accelerant, 15-20 percent of filler, 1-3 percent of vulcanizer and 0.5-1.5 percent of tackifier, wherein the accelerant is a mixture composed of a vulcanizing accelerant, an antioxidant, an antiager and polyethylene glycol. In the invention, the natural rubber is adopted to serve as a major ingredient of the adhesive, so that the adhesive has high tensile strength, protects the environment and enhances the stability; various accelerants are chosen in the formula for synergistic action to ensure that the adhesive body has the special effect of seawater resistance; and white smoke is served as the filler to ensure that the gluewater has uniform hardness degree and withstands high temperature. The tension of the adhesive is 4-6KG, and the tensile strength performance is excellent.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to adhesives used in the fields of diving and ship supplies. Background technique [0002] For a long time, the production of shoes, handbags and luggage, and the bonding of decorative materials have been mainly using solvent rubber adhesives. Commonly known in the market as 101 raw rubber paste, 103 powder rubber paste, all-purpose glue, etc. This type of adhesive in the known technology is generally prepared by stirring natural rubber or neoprene and adding tackifying resin into a reactor according to a certain ratio and stirring until dissolved by using a solvent. This type of adhesive emits 80% organic solvents, such as toluene and chlorinated solvents, to the atmosphere during use. The high content of organic solvents in the air seriously pollutes the environment. At the same time, due to the use of solvent-based adhesives, there are flammable and explosive problems, and th...
