Description
Technical field
The present invention relates to automobile lamp components production technical fields, more particularly to a kind of automobile lamp hot-melt adhesive.
Background technique
Automobile lamp hot glue is widely used on the lamps and lanterns such as automobile front, rear taillight and front fog lamp, and hot melt adhesive requires to have
Higher softening point, stronger cohesive force, preferable uviolresistance, ageing resistance.Automobile lamp hot-melt adhesive master is prepared at present
It is different with ethylene-vinyl acetate copolymer (EVA), styrene-butadiene-styrene triblock copolymer (SBS), styrene-
Material based on isoprene-styrene triblock copolymer (SIS), hot melt adhesive softening point made from EVA is lower, poor adhesion,
High temperature resistance is poor, and softening point can only achieve 120 DEG C, and high temperature resistance is poor, is unable to satisfy sedan lamp and train headlamp
It is required that can only be used on some car lights of less demanding such as Motorcycle headlight, agricultural car light, it is past in order to improve EVA gum softening point
Toward the content for increasing material of main part, the result is that melt viscosity is excessive, and can not be glued；The hot melt adhesive prepared using SBS elastomer,
The disadvantage is that high temperature is easily crosslinked aging, so that overall performance declines；The hot melt adhesive prepared using SIS elastomer, the disadvantage is that high temperature is easy
It decomposes, makes hot melt adhesive cohesive force, shear strength decline, it is unqualified so as to cause bonding force.
Summary of the invention
In view of the above problems, hot melt adhesive softening point is high the purpose of the present invention is to provide a kind of automobile lamp hot-melt adhesive, glue
Resultant force is strong, and resistance to ag(e)ing is good.
The technical scheme is that be accomplished by the following way: a kind of automobile lamp hot-melt adhesive, it is characterised in that: institute
The hot melt adhesive stated is made of the raw material of following weight parts: SEBS thermoplastic elastomer (TPE) 97-100, chlorinated paraffin 12-15, hexichol
Dicyclohexylmethane diisocyanate 4-6, polycarbonate 6-8, nanometer bauxite 2-3, isothiazolinone 0.4-1, polyvinylidene fluoride 1-
2, trisnonyl phenyl phosphite 2-4, β-hydroxyalkyl amide 0.5-1, boron oxide 0.2-0.4, double isooctyl mercaptoacetate two are just pungent
The more alkoxy ether copolymer 1-2 of base tin 0.1-0.3, polysiloxanes-, tackifier 12-17, antioxidant 1-2.
The tackifier are made of the raw material of following weight parts: polyadipate -1,4-butanediol esterdiol 10-
16, tertiary carbonic acid glycidyl ester 2-3, hydrogenated rosin 10-14, silane coupling agent KH560 1-2, borax 1-2, turpentine oil 0.5-1.
Above-mentioned polyadipate -1,4-butanediol esterdiol is heated to 75-80 DEG C, borax is added, reduces after mixing evenly
Temperature is 55-60 DEG C, and hydrogenated rosin is added, insulated and stirred 3-5 minutes, silane coupling agent KH560 is added, 400-500 revs/min is stirred
Dispersion 10-12 minutes is mixed, remaining each raw material is added, dries after being sufficiently mixed to get the tackifier.
The antioxidant is BHT264.
Hot melt adhesive softening point of the present invention is high, and bonding force is strong, and resistance to ag(e)ing is good, and flexibility is good, good film-forming property, environmental protection, no dirt
Dye.
