Abstract
The invention provides a kind of PUR, hot-melt adhesive composition includes：(A) acrylic block copolymers：100 parts by weight；(B) ethylene ethyl acrylate：5 15 parts by weight；(C) ethylene methacrylic acid：15 parts by weight；(D) tackifying resin：5 50 parts by weight；(E) mineral oil：2 10 parts by weight.The PUR (30 DEG C 150 DEG C) in the temperature range of broadness keeps excellent adhesive effect to unorganic glass and polar plas (PMMA, PC, ABS, PVC etc.).Especially, the glass headlight (it is required that temperature resistant range is at 30 150 DEG C) of most trucies can be bonded and be sealed with PUR of the present invention, substitute now widely used silica gel.Silica gel efficiency is low, and the release of crosslinking dose of functional group, and forming spray in lamp housing influences transparency.Bonding process simple and fast is because PUR cooling solidifies.
Description
Technical field
The present invention relates to PUR, the bonding being particularly directed in glass car light production process and sealing.
Background technology
Truck glass car light is typically bonded and sealed with silica gel, but silica gel efficiency is low, has small molecule volatile matter to remain in
Spray is formed in car light, influences transparency.Traditional hot-melt adhesive high temperature resistant scope can only achieve 80 DEG C.PUR of the present invention then can
Solve the problems, such as that traditional hot-melt adhesive high temperature resistant is insufficient and silica gel efficiency is low and hazes.
The content of the invention
For the deficiencies in the prior art, it is an object of the invention to provide a kind of rational in infrastructure, easy to use one
Kind PUR, it solves these above-mentioned problems.
The technical solution adopted in the present invention is as follows：A kind of PUR,
Hot-melt adhesive composition includes：
(A) acrylic block copolymers：100 parts by weight；
(B) ethylene ethyl acrylate：5-15 parts by weight；
(C) ethylene methacrylic acid：1-5 parts by weight；
(D) tackifying resin：5-50 parts by weight；
(E) mineral oil：2-10 parts by weight.
Preferably, wherein described acrylic block copolymers are methyl methacrylate-b- butyl acrylate-b- methyl
Methyl acrylate triblock copolymer.
Preferably, wherein described ethylene ethyl acrylate contains the 10-25% of parts by weight percent ethyl acrylate
Preferably, wherein described tackifying resin includes C-9 Petropols.
Preferably, wherein described tackifying resin includes C-5 Petropols.、
Preferably, wherein described tackifying resin includes C-5/C-9 Petropols.
Preferably, wherein described tackifying resin includes being based on alpha- methyl styrenes (AMS) pure monomer resin.
Preferably, wherein described mineral oil includes naphthenic oil and paraffin oil.
Beneficial effects of the present invention include：
The PUR of the invention includes acrylic block copolymers, ethylene ethyl acrylate (EEA), tackifying resin and mineral
Oil.The PUR 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, most trucies glass headlight (it is required that temperature resistant range-
30-150 DEG C) it can be bonded and be sealed with PUR of the present invention, substitute now widely used silica gel.Silica gel efficiency is low (to need 24
Hour hardening time) and crosslinking dose of functional group release (a kind of volatilizable composition), lamp housing formed spray influence it is saturating
Lightness.The present invention is free of solvent, does not chemically react, and bonding process simple and fast is because PUR cooling solidifies.Use the longevity
Life length, stability are high, it is possible to increase the performance of car light, cost are greatly lowered than existing products in markets, are advantageous to advise greatly
Mould produces.
