Abstract
The invention provides a radioresistant, high temperature resistant and waterproof sealing rubber belt. Rubber is degraded by a basal body of an open mill through mastication, and is additionally provided with viscosity increaser, reinforcing filler, age resistor and radioresistant rubber; the operation of milling is carried out repeatedly until the materials are uniformly mixed; and the well mixed materials are cut into stripe-shaped standard sample stripes, and the radioresistant, high temperature resistant and waterproof sealing rubber belt can be obtained. The invention adopts the mixture of butyl rubber and ethylene propylene terpolymer rubber; under high irradiation dose, the cross bonding and the degrading parts of the two rubbers are counteracted and combined with each other to maintain the properties of the sealing rubber belt; and the compatibility of the radioresistant silicon rubber and the basal body is good, and the dose of the age inhibitor is slightly higher than the dose in a normal rubber system so as to enhance the high temperature property and the radioresistant property of the sealing rubber belt.
Description
Technical field
The present invention relates to a kind of anti-irradiation, high temperature resistant, water-proof seal adhesive tape, the preparation technology of sealing adhesive tape also is provided simultaneously, belong to cable accessory manufacturing technology field.
Background technology
Along with developing rapidly of nation-building cause, rubber plastic cable is used widely in all trades and professions, and the docking of moulding the cable splice place for rafter requires also more and more higher, should convenient construction, again firm and durable.Develop insulation, waterproof, self-adhesion sealant tape take isoprene-isobutylene rubber as main base material for this reason, and used it for the joint of rubber plastic cable, obtained good effect.
The isoprene-isobutylene rubber water-proof seal adhesive tape is the elastoplasticity sealing tape of making take saturated polyisobutylene rubber, isoprene-isobutylene rubber etc. as main raw material.This series products has excellent resistance to air loss, watertightness, good autohension, extensibility, weathering resistance, lower temperature resistance and water tolerance, solvent-free pollution, the i.e. characteristics such as sticking i.e. usefulness, construction safety convenience.But saturated polyisobutylene rubber, isoprene-isobutylene rubber are typical irradiation to crack polymkeric substance.The tensile strength at yield of this type of water-proof seal adhesive tape, flexibility, recovery of elasticity and elongation at break all increase with irradiation dose and obviously descend, when it is used for high radiation field institute (such as Nuclear power plants, aerospace etc.), will lose the effects such as its original insulation, waterproof, self-adhesion.
Summary of the invention
Main purpose of the present invention is by selecting suitable base rubber, and adds anti-irradiation composition and prepare a kind of anti-irradiation, resistant to elevated temperatures insulation water-proof seal adhesive tape.
The present invention also provides the preparation method of above-mentioned sealant tape, is applicable to suitability for industrialized production.
The anti-irradiation of the present invention, resistant to elevated temperatures insulation water-proof seal adhesive tape are comprised of by mass parts following material:
The water proof rubber matrix of 15-30 part, the tackifier of 20-30 part, the reinforcing filler of 15-30 part, the anti-aging agent of 0.5-5 part, the rubber of anti-irradiation of 1-10 part.
The rubber matrix that the present invention adopts is the mixture of terpolymer EP rubber and isoprene-isobutylene rubber, and its blending ratio is: (1～2): (1～2).
It is tackifier that the present invention adopts terpine resin and polyisobutene, and its blending ratio is: (1～1.5): 1.
It is reinforcing filler that the present invention adopts aluminium hydroxide.
The anti-aging agent that the present invention adopts is antioxidant MB or anti-aging agent RD or both mixtures.
The rubber of anti-irradiation that the present invention adopts is silicon rubber.
The concrete preparation method of the anti-irradiation of the present invention, resistant to elevated temperatures insulation water-proof seal adhesive tape is as follows:
The rubber of 15-30 part is degraded with mill matrix mastication, add the tackifier of 20-30 part, the reinforcing filler of 15-30 part, the anti-aging agent of 0.5-5 part, the rubber of anti-irradiation of 1-10 part, repeatedly mixing, until material is mixing evenly.The material that mixes is cut into strip, is strip with extruder for shaping, adopts automatic cutting means, is cut into the standard batten of 350 * 25 * 1.8mm, just obtains anti-irradiation, resistant to elevated temperatures insulation water-proof seal adhesive tape.
Positively effect of the present invention is: the anti-irradiation that obtains, resistant to elevated temperatures insulation water-proof seal adhesive tape, adopt the mixture of isoprene-isobutylene rubber and terpolymer EP rubber: wherein isoprene-isobutylene rubber is the irradiation-induced degradation type, and terpolymer EP rubber is irradiation crosslinking type, under high irradiation dose, two kinds of rubber crosslinked and degraded partial offset interosculate to keep the performance of sealant tape; The consistency of selected anti-irradiation silicon rubber and matrix is better in addition, and the amount of anti-aging agent is larger than the amount in the normal rubbery system, strengthens its high-temperature behavior and radiation-resistant property.
