Abstract
The invention provides hot melt adhesive. A hot melt adhesive composition comprises 100 parts by weight of crylic acid block copolymer (A), 5 to 15 parts by weight of ethylene acrylic ester (B), 1 to 5 parts by weight of ethylene methyl crylic acid (C), 5 to 50 parts by weight of tackifying resin (D), and 2 to 10 parts by weight of mineral oil (E). The hot melt adhesive remains outstanding effect on adhering inorganic glass and polar plastics (such as PMMA, PC, ABS and PVC) under a wide temperature interval (-30 to 150 DEG C); the most of glass headlamps (the requirement on temperature resistance range from -30 to 150 DEG C is met) of trucks can be particularly adhered and sealed through the hot melt adhesive instead of the currently widely used silica gel which is small in efficiency and leads to release of crosslinking agent functional groups as well as forming fog-like substances on lamp housing to influence the transparence; the hot melt adhesive is solidified as being cooled, so that the adhering is simple and quick.
Description
Technical field
The present invention relates to hot melt adhesive, particularly for the bonding and sealing in glass car light production process.
Background technology
Truck glass car light generally carrys out bonding and sealing with silica gel, but silica gel efficiency is low, has small molecules volatile matter to remain in car light and forms spray, affect transparency.Traditional hot-melt adhesive is high temperature resistant, and scope can only reach 80 DEG C.Hot melt adhesive of the present invention then can solve the high temperature resistant deficiency of traditional hot-melt adhesive and the low problem with hazing of silica gel efficiency.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide a kind of rational in infrastructure, a kind of hot melt adhesive easy to use, it solves these above-mentioned problems.
The technical solution adopted in the present invention is as follows: a kind of hot melt adhesive,
Hot-melt adhesive composition comprises:
(A) acrylic block copolymers: 100 parts by weight;
(B) ethylene ethyl acrylate: 5-15 part by weight;
(C) ethylene methacrylic acid: 1-5 part by weight;
(D) tackifying resin: 5-50 part by weight;
(E) mineral oil: 2-10 part by weight.
Preferably, wherein said acrylic block copolymers is methyl methacrylate-b-butyl acrylate-b-methyl methacrylate triblock copolymer.
Preferably, wherein said ethylene ethyl acrylate contains the ethyl propenoate of weight part percent 10-25%
Preferably, wherein said tackifying resin comprises C-9 petroleum resin.
Preferably, wherein said tackifying resin comprises C-5 petroleum resin.、
Preferably, wherein said tackifying resin comprises C-5/C-9 petroleum resin.
Preferably, wherein said tackifying resin comprises based on alpha-vinyl toluene (AMS) pure monomer resin.
Preferably, wherein said mineral oil comprises naphthenic oil and paraffin oil.
Beneficial effect of the present invention comprises:
This hot melt adhesive of the present invention comprises acrylic block copolymers, ethylene ethyl acrylate (EEA), tackifying resin and mineral oil.This hot melt adhesive in the temperature range of broadness (-30 DEG C-150 DEG C) to unorganic glass and polar plas (PMMA, PC, ABS, PVC.。。。。。) keep excellent adhesive effect.Especially, the glass headlight (requiring that temperature resistant range is at-30-150 DEG C) of most truck can carry out bonding and sealing with hot melt adhesive of the present invention, replaces now widely used silica gel.Silica gel the efficiency low set time of 24 hours (need) and have the release of linker functional group (a kind of volatilizable composition), forming spray at lamp housing affects transparency.The present invention containing solvent, does not have chemical reaction, and bonding process simple and fast is because namely hot melt adhesive cooling solidifies.Long service life, stability is high, and can improve the use properties of car light, cost significantly reduces than existing products in markets, is conducive to scale operation.
