Description
Technical field
The present invention relates to butyl rubber hot-fusible pressure-sensitive adhesive fields, are heated more particularly to a kind of butyl rubber of cohesion enhancing
Pressure sensitive adhesive and preparation method thereof.
Background technology
Pressure sensitive adhesive is a kind of material for implementing interfacial adhesion by pressure.According to matrix resin ingredient can be divided into rubber-type and
Tackifying resin, plasticizer, filler, antioxygen will be also added in addition to main component is rubber in two class of resin type, rubber pressure sensitive adhesive
The auxiliary agents such as agent, anti-aging agent even vulcanizing agent.In rubber pressure sensitive adhesive, butyl type rubber pressure sensitive adhesive is because it is containing less unsaturation
The presence of double bond and methyl group has very excellent weatherability and watertightness.Therefore be mostly used building, medical treatment and
Industrial circle makees waterproof, be sealing adhesive materials'use.Belong to environment-friendly solvent-free, the weather-proof and excellent adhesive backers of adhesive property.
The method of traditional butyl rubber hot-fusible pressure-sensitive adhesive generally use unvulcanised makes, and such pressure sensitive adhesive has good
Good flowing wellability.Such as 102827557 A of patent CN are with butyl rubber, polyisobutene, random polypropylene, SBS, white oil,
Plasticizer, phenol-formaldehyde resin modified, light dydrocarbon resin and other auxiliary agents etc. make hot-fusible pressure-sensitive adhesive, have good leakproofness
Energy and mechanical property, can be used for solar energy solar double-glass assemblies rim seal, 1800 peel strengths reach 3.15-4.20N/mm.Specially
102277104 A of sharp CN provide a kind of preparation of the butyl pressure sensitive adhesive for self-adhering type rubber fastening band, wherein butyl rubber
100, polyisobutene 30-70, solid terpenes resin 30-90, liquid terpene resins 30-70, ultrafine kaolin 150-250.It is shelled
It is 1.84N/mm from intensity.Zhu Jinxin etc. (Chinese adhesive, 11 phases of volume 19 in 2010, page 10) is opposite with butyl rubber and height
The polyisobutene of molecular mass is aided with the additives such as tackifying resin, plasticizer and reinforcing filler as matrix resin, is prepared for
Good insulation preformance, the low telecommunications equipment waterproof insulation pressure sensitive adhesive of water absorption rate.In order to increase the cohesive strength of adhesive, also have
Take the method that vulcanization crosslinking is carried out to rubber.Such as 1521204 A of patent CN with butyl rubber, accelerating agent (sulfurization),
Softening agent, reinforcing agent and surfactant etc. prepare pressure-sensitive self-repairing waterproof rubber, are used for work China Democratic National Construction Association waterproof.Patent CN
105670534 A add molybdenum dioxide, divinylbenzene, triphenyl phosphate and wetting agent in butyl pressure sensitive adhesive, are keeping good
While good tack, the cohesive force for making glue have again catches mosquito for viscous.
The caking property of pressure sensitive adhesive is divided into tack and holds viscosity, these caking property are removed to be had outside the Pass with tackifying resin, and also and glue
Mobility and cohesive strength have much relations.Usual good fluidity, all right with the wellability of adhesive surface, adhesion strength is just high；
The cohesive strength of glue itself is high, and the cohesional failure power of glue is with regard to big.The molecular weight of wherein rubber matrix resin is higher, the cohesive force of glue
It is bigger, but mobility variation is easily caused, undesirable consequence can be all caused in the preparation and coating of glue and bonding process.Cause
This less rubber using high molecular weight or the method using vulcanization.So usually carrying out high temperature vulcanized method again after application
It realizes.Especially in terms of hot-fusible pressure-sensitive adhesive, good cohesive strength can be achieved using vulcanization.But chemical cure be it is irreversible,
After vulcanization bonds, it is impossible to remove bond again again, even if heating is also impossible to the bonding wellability having had again.
Invention content
It is an object of the invention to cannot be removed after solving the adhesion strength of prior art difference or irreversible vulcanization
Cohesive problem again.
Purpose of the present invention is to what is be achieved through the following technical solutions：
A kind of butyl rubber hot-fusible pressure-sensitive adhesive of cohesion enhancing, component and parts by weight are：Butyl rubber 10-35%, bromine
Change butyl rubber 3-20%, other matrix resin 3-18%, imdazole derivatives 0.05-1%, tackifying resin 10-35%, plasticizer
5-35%, reinforcing filler 18-55%, antioxidant 0.1-0.6%.
Can also be that a kind of butyl rubber hot-fusible pressure-sensitive adhesive of cohesion enhancing, component and parts by weight are：Butyl rubber
20-30%, brombutyl 5-15%, other matrix resin 5-15%, imdazole derivatives 0.1-0.5%, tackifying resin 15-
30%, plasticizer 10-30%, reinforcing filler 25-50%, antioxidant 0.2-0.4%.
Preferably, other matrix resins are polyisobutylene resin of the molecular weight in 20000-80000 high molecular weight,
Styrene-isoprene-styrene block copolymer (SIS), one in Styrene-Butadiene-Styrene Block Copolymer SBS
Kind is several.
Preferably, the imdazole derivatives refer to the 2- ethyl imidazol(e)s containing imidazole group, N- butyl imidazoles, N- vinyl

The method of crosslinking points is managed to prepare hot-fusible pressure-sensitive adhesive, is had the positive effect that compared with traditional butyl pressure sensitive adhesive：
1) there is excellent cohesive strength butyl hot-melt pressure sensitive adhesive can be improved while tack hardly declines
Holding power and peel strength, its 180 ° of peel strengths reach 5.5N/mm at 23 DEG C；Its 180 ° of peel strengths reach 4.5N/mm at 50 DEG C,
With good heat resistance.
2) the butyl rubber hot-fusible pressure-sensitive adhesive has reversible hot-workability, and there is coating again to bond in a heated state
Ability；
3) contain certain polar group in the butyl hot-melt pressure sensitive adhesive, there is the energy for bonding polarity and apolar surfaces
Power；
4) the butyl hot-melt pressure sensitive adhesive has excellent weatherability, watertightness and air-tightness；
5) the butyl hot-melt pressure sensitive adhesive can be used for building, medical treatment, automobile, electric power, the industries such as petrochemical industry.
Suitable bromination fourth is added by means of Ionomer (referred to as " from aggressiveness ") method in the present invention in butyl rubber
Base rubber, and imdazole derivatives are added, ionizable side group on butyl rubber main chain, band are become with imdazole derivatives substitution bromine
The imidazole group of positive charge while meeting charge balance with negatively charged bromide ion multiple ions also form forming for ionic bond
It closes, i.e., forms the ion cluster of imidazoles side group at normal temperatures, these ion clusters become the physical crosslinking point of brombutyl, play
Crosslinking increases the effect of adhesive cohesive strength.Different from chemical cure, these ion clusters can dissociate under high temperature, and cross-bond disappears
It loses, there is thermoplasticity, mobility can be increased and be conducive to be coated with cohesive processing.
