Embodiment 1

[0024] A preparation method with special adhesive composite resin, the steps are as follows:

[0025] (1) Manufacturing method of rubber initial tack resin: Take 1000 parts of terpene-rich fraction, 500 parts of C5 fraction, and 1 part of catalyst, stir at -20~+10°C and pressure of 1.5-2 MPa React for 2~10 hours. After the reaction is completed, add 2 parts of ethanol at -10~+10°C, stir at a constant temperature for 1~2 hours, and let the layers stand for 2~3 hours. Take the lower layer of liquid and store it at 150~200°C. Under reduced pressure, the residual fraction was removed by distillation under reduced pressure to obtain 1000~1200 parts of adhesive resin, that is, initial tack resin, which is yellow in color and has a softening point of 60~65°C.

Abstract

The invention provides a preparation method for special adhesive composite resin. The method comprises the following steps: (1) taking 1,000 parts of a terpene-rich fraction, 500 parts of a C5 fraction, and 1 part of liquid aluminum trichloride, after a reaction under stirring is completed, adding 2 parts of ethanol, performing stirring at a constant temperature, allowing the stirred material tostand for layering, taking a liquid at the lower layer, and performing distillation under reduced pressure to obtain adhesive resin; (2) taking 600 parts of the adhesive resin obtained in the step (1), mixing the taken adhesive resin, 150 parts of styrene-indene resin, 150 parts of alkyne resin and 100 parts of 1102 resin, and performing a reaction at a temperature of 200-260 DEG C to obtain mixedadhesive resin; and (3) taking 800 parts of the adhesive resin obtained in the step (2), reacting the taken 800 parts of the adhesive resin with 200 parts of white carbon black at a temperature of 260-280 DEG C to obtain the special adhesive composite resin. The adhesive composite resin prepared by the method has initial adhesion, final adhesion, and excellent rubber stiffness, and can be used inthe manufacture of rubber inner tubes, butyl rubber inner tubes and high-strength butyl inner tubes, the process is simplified, the operation is simple, and the method is beneficial to improving thefinished-product rate.

Description

technical field [0001] The invention relates to the technical field of composite resin materials, in particular to a preparation method of composite resin with special bonding. Background technique [0002] For many years, in the manufacture of rubber inner tubes and butyl inner tubes (hereinafter referred to as inner tubes), the technology of inner tube joints is more critical, and the cutting technology of inner tubes is particularly important. Cutting with a cutter requires the incision to be straight and not deformed. If deformation occurs, the inner tube will easily deviate and be uneven when the seam is aligned, resulting in defects such as pressure bearing and tear resistance and air leakage, resulting in waste tires. Therefore, it is required to meet high technical indicators when mixing tires, and should have the following special requirements: (1) good initial adhesion, and the joints can be automatically bonded when they are butt-joint; (2) good final adhesion, an...
