Description
Technical field
The present invention relates to the technical field of hot-fusible pressure-sensitive adhesive more particularly to a kind of melt pressure sensitives for PVC electrical adhesive tape
Glue and preparation method.
Background technique
The scientific name of electrical adhesive tape is polyvinyl chloride electric insulating tape, is usually referred to as electric insulation adhesive tape or exhausted in the industry
Edge adhesive tape, also referred to as PVC electrical adhesive tape.PVC electrical adhesive tape is to coat rubber using soft PVC (PVC) film as substrate
Glue-type pressure sensitive adhesive is fabricated, and is had the characteristics such as good insulation, resistance to combustion, proof voltage, cold-resistant, is suitable for being used for various resistance zero
The insulation of part.PVC film has the characteristics such as electrical insulation properties, anti-flammability, weather-proof, and rubber pressure-sensitive adhesive has tack and glues
Knotting strength, the insulation suitable for all kinds of wire and cables is wound, while can provide the performances such as mechanical protection, acid and alkali-resistance, weather-proof.Wherein
Hot-fusible pressure-sensitive adhesive is widely used.Hot-fusible pressure-sensitive adhesive is the adhesive based on thermoplastic polymer, has hot melt and pressure-sensitive pair concurrently
Weight characteristic, is coated in the molten state, apply after cooling and solidifying slight finger pressure can rapid link, while appearance can be compared again
It is easily stripped, does not pollute the surface of adherend.Hot-fusible pressure-sensitive adhesive includes thermoplastic elastomer hot-melt pressure sensitive adhesives, esters of acrylic acid
Hot-fusible pressure-sensitive adhesive, unformed polyolefin hot-fusible pressure-sensitive adhesive and other types.
But thermoplastic elastomer (TPE) class hot-fusible pressure-sensitive adhesive there is no to be applied on PVC electrical adhesive tape at present, main cause
It is that the hot-fusible pressure-sensitive adhesive of conventional use of thermoplastic elastomer (TPE) class is due to by the migration of plasticizer in electrical adhesive tape PVC film
It influences and the characteristics of PVC film polarity itself, glue-line can soften completely or glue-line can move to the back side of film, cannot be formed
Adhesive tape.It is limited by very large so thermoplastic elastomer (TPE) class hot-fusible pressure-sensitive adhesive is applied on PVC electrical adhesive tape.
Summary of the invention
In view of the deficiencies of the prior art, one of the objects of the present invention is to provide a kind of hot melts for PVC electrical adhesive tape

Wherein, the thermoplastic elastomer (TPE) is one of SBS, SIS, SEBS, butyl rubber, butadiene-styrene rubber or at least two
Kind, for bulk elastomer described in the present invention；
SBS styrene analog thermoplastic elastomer is three sections of copolymers of styrene-butadiene styrene, also known as thermoplasticity fourth
Benzene block copolymer or thermoplastic styrene butadiene rubber, abbreviation SBS.The dissolubility and thermoplasticity of the existing polystyrene of SBS (PS), and have
There are the flexibility and resilience of butadiene rubber (PB).SBS dissolubility is good, all compatible with many polymer, is not required to high temperature vulcanized, adds
Its melting viscosity can be reduced by entering resin and tackifier, be very suitable to prepare hot-fusible pressure-sensitive adhesive.
SIS styrene-isoprene-styrene block copolymer SIS is the block copolymer of styrene and isoprene,
It is sisters' product of SBS, its modulus is low, and solution viscosity and melting viscosity are small, and processing performance is good, since SIS mid-block is poly-
Isoprene has pendant methyl in structure, it is made to have good cohesive force and excellent adhesion property and add with other
Add the good compatibility of object, therefore hot-fusible pressure-sensitive adhesive ratio SBS system, SIS system hot-fusible pressure-sensitive adhesive initial cohesiveness is more excellent, since SIS has
Excellent bellow seal and high temperature retentivity is usually used in and SBS or other materials configuration adhesive.
SEBS is saturation type SBS or Hydrogenated SBS, is to add hydrogen that double bond is made to be saturated and be made by extraordinary type SBS, SBS exists
Moderately orientation adds hydrogen in the presence of catalyst, then so that polybutadiene segments is hydrogenated to polyethylene (E) and polybutene (B) chain drum, therefore claim
For SEBS.SEBS is generally harder, and rigidity is stronger, and modulus is higher, and tensile strength ratio is significantly increased before adding hydrogen, pulls apart elongation
Rate decline.SEBS due in strand double bond without or seldom, therefore obviously improve to photooxidation, the ageing-resistant performance of ozone.SEBS
With excellent ageing-resistant performance, not only there is plasticity, but also with high resiliency, without the i.e. processable use of vulcanization, leftover pieces can
Use again, be widely used in produce high-grade elastomer, modifying plastics, adhesive, lubricant tackifier, wire and cable filler material and
Protective cover material etc..
It is anti-that butyl rubber is that isobutene and isoprene carry out cationic polymerization under Friedel-Craft catalyst action
The product answered.Since butyl rubber has excellent air-tightness and good heat-resisting, ageing-resistant, acid and alkali-resistance, resistance to ozone, resistance to molten
Agent, electrical isolation, damping and it is low water suction etc. performances so that its be widely used in the inner tube of a tyre, curing bag, curing bag, inner liner, sidewall,
Wire and cable, waterproof building material, vibration-absorptive material, medicinal bottle stopper, food (chewing gum base), part for rubber dam, poison gas protection equipment, bonding
Agent, inner tube valve core, anticorrosive article, the rotation of harbour ship shield, bridge support pads and hot material conveyor belt etc., fourth of the invention
Base rubber can carry out elevated temperature strength for hot-melt pressure sensitive adhesive tape.
Butadiene-styrene rubber (SBR), also known as polystyrenebutadienes copolymer, physical mechanism performance, processing performance and product
Service performance close to natural rubber, some performances are for example wear-resisting, heat-resisting, ageing-resistant and curingprocess rate is more excellent compared with natural rubber
It is good, it can be used in combination with natural rubber and various synthetic rubber.
Wherein, the tackifying resin is one of terpenes, Petropols, rosin or at least two；Tackifying resin is
Except another external most important its main function of ingredient of body elastic is to give pressure sensitive adhesive with necessary in pressure-sensitive adhesive
Viscosity.That is producing mixed system to by viscous material surface just because of tackifying resin has been mixed into rubber elastomer
Raw necessary tack and bonding force, just become a real pressure-sensitive adhesive.Due to thermoplastics such as SBS, SIS, SEBS
Property elastomer no adhesion itself, so need to be added tackifying resin to improve wetability, initial bonding strength, peel strength, Yi Jihe
Suitable polarity and with the compatibility of bulk elastomer etc., suitable polarity makes good between hot-fusible pressure-sensitive adhesive and material to be bonded
Cohesive force.In addition, tackifying resin can reduce the melt viscosity of system, improve coating performance.
Wherein, the softening agent is naphthenic oil, provides the machinability and tack of hot-fusible pressure-sensitive adhesive.
Wherein, the antioxidant is antioxidant 1010 and irgasfos 168, provides the anti ageing property of hot-fusible pressure-sensitive adhesive.
Preferably, a kind of hot-fusible pressure-sensitive adhesive for PVC electrical adhesive tape includes by weight following raw material: 20~90
