Description
Technical field
The present invention relates to the hot melt adhesive that a kind of automobile plastic, metal, glass light fixture adhering and sealing are used.
Background technology
The tackiness agent that uses in automobile lamp production mostly is two component epoxy glue and polyurethane reactive hot melt glue greatly.Two component epoxy glue cost is low, is extensive use of on the low side light fixture, but cured glue body hardness height, embrittlement is chapped easily, and vibration resistance is poor, and weathering resistance is also poor, and set time is long, and production efficiency is low; The gluing intensity height that connects of polyurethane reactive hot melt, vibration resistance is excellent, uses morely on the high-end automobile lamp product, but cost is very high, set time is long, and very easily stops up the applying glue spray gun.Therefore, provide that cost is low, vibration resistance good, good weatherability, production time are short, easy to operate tackiness agent is the target that auto lamp adhesive is allotted development.
Chinese invention patent ublic specification of application CN1597826A provides a kind of prescription of polyamide hot, can be used for the adhering and sealing of automobile metal, plastics light fixture.Be that (1.0～2.5Mpa) times polycondensations 1～4 hour, discharging after the polycondensation, wire drawing, cooling, section obtain hot-melt film at high temperature (200 ℃～300 ℃) high pressure by a certain percentage by hexanolactam, nylon salt, diamine, diprotic acid.This hot melt adhesive complex manufacturing, the equipment requirements height has increased production cost, and applying glue inconvenience during use is not good to the adhesive effect of glass light fixture.
Chinese invention patent ublic specification of application CN1887999A provides a kind of prescription of hot melt adhesive, comprise styrene isoprene styrene block copolymer (SIS) (SIS), ethylene-vinyl acetate copolymer (EVA), ethylene-ethyl acrylate copolymer (EEA), tackifying resin, organic montmorillonoid, oxidation inhibitor etc., produce with twin screw extruder under the heat, being used for polyethylene pipe repairs bonding, this hot melt adhesive melt viscosity is very big, the inconvenience applying glue is to the metal sticking weak effect.
Summary of the invention
The present invention overcomes the deficiencies in the prior art, provides a kind of cost low, and adhesiveproperties is excellent, vibration resistance is good, and weathering resistance is good, and the production time is short, not stifled spray gun simple to operate, environmentally friendly, be applicable to the hot melt adhesive that most of small-sized and middle shaped metals, plastic and glass automobile lamp adhering and sealing are used.
Technical scheme of the present invention is: a kind of automobile hot melt light fixture glue is characterized in that comprising following component (mass percent):
Styrene isoprene styrene block copolymer (SIS) (SIS) 20%～30%, wherein styrene content 14%～16%;
Styrene-ethylene-butylene-styrene segmented copolymer (SEBS) 20%～30%, wherein styrene content 30%～33%;
Tackifying resin 25%～35%, look number is not more than 5;
Light calcium carbonate 5%～10%, granularity 0.5 μ～12 μ;
