The present invention discloses a kind of water proof type foaming hot-fusible pressure-sensitive adhesive for arrangements for automotive doors, includes following component by mass parts: acrylic ester polymer 80-93%；Tackifying resin 0-20%；Antioxidant 0.3-3%；Wherein, acrylic ester polymer includes following component by mass parts: soft monomer 80-92%；Hard monomer 1-8%；Function monomer 1-4%；Molecular weight regulator 0-1%；Initiator 0.1-0.5%；Crosslinking agent 1-8%, the preparation method for the water proof type foaming hot-fusible pressure-sensitive adhesive that the invention also discloses this for arrangements for automotive doors, the foaming hot-fusible pressure-sensitive adhesive obtained by above-mentioned formula and preparation method not only has preferable peel strength, have at high temperature and holds viscous intensity well, there is good thermal stability simultaneously, and smell grading is low.
Description
Technical field
The present invention relates to technical field of hot-melt pressure-sensitive adhesive more particularly to a kind of water proof type for arrangements for automotive doors to foam and heat
Pressure sensitive adhesive and preparation method thereof.
Background technique
Hot-fusible pressure-sensitive adhesive generally comprises four kinds of ingredients: thermoplastic elastomer (TPE), tackifying resin, plasticizer and antioxidant, wherein
Thermoplastic elastomer (TPE) includes styrene block copolymer, ethylene-vinyl acetate copolymer and unformed polyolefin, with benzene second
Based on alkene block copolymer (abbreviation SBC).Hot-melt pressure sensitive adhesive is the third generation after solution-type and emulsion-type pressure-sensitive
Pressure sensitive adhesive product, application range is more extensive, compared to traditional solution-type and emulsion-type pressure-sensitive, has cost of investment
Low, process velocity is fast, and solvent, nonhazardous, no waste liquid, the features such as being good for the environment and keep the safety in production are not used in production.
For from molecular structure, conventional hot melt pressure sensitive adhesive still falls within thermoplastic polymer, between molecular weight substantially not
Containing cross-linked structure, there are obvious gaps for cohesive strength, heat resistance and solvent resistance and pressure-sensitive acrylate.In fact,
This problem can be solved by introducing crosslinked system, make such hot-fusible pressure-sensitive adhesive that can both retain common hot-fusible pressure-sensitive adhesive
Performance characteristics, and can further solve the problems such as common hot-fusible pressure-sensitive adhesive cohesive strength is low, temperature tolerance is poor and smell is big.
Summary of the invention
It is an object of the invention to be directed to the existing state of the art, a kind of water proof type foaming heat for arrangements for automotive doors is provided
Molten pressure sensitive adhesive and preparation method thereof, the foamed material cohesive strength is big, and heat-resisting and ageing-resistant performance is good, and smell grading is low.
In order to achieve the above objectives, the present invention adopts the following technical scheme:
A kind of water proof type foaming hot-fusible pressure-sensitive adhesive for arrangements for automotive doors, includes following component by mass parts:
Acrylic ester polymer 80-93%；
Tackifying resin 0-20%；
Antioxidant 0.3-3%；
Wherein, acrylic ester polymer includes following component by mass parts:
Preferably, the soft monomer is selected from one or both of butyl acrylate, acrylic acid-2-ethyl caproite group
It closes.
Preferably, the hard monomer be selected from methyl acrylate, methyl methacrylate, vinyl acetate, styrene,
The combination of one or more of acrylonitrile, ethyl methacrylate, n-BMA.
Preferably, the function monomer is selected from acrylic acid, methacrylic acid, maleic acid, maleic anhydride, acryloyl
Amine, dimethylacrylamide, propenoic acid beta-hydroxy ethyl ester, β-hydroxyethyl methacry-late, propenoic acid beta-hydroxy propyl ester, methacrylic acid
β-hydroxypropyl acrylate, glycidyl acrylate, glycidyl methacrylate, N hydroxymethyl acrylamide, itaconic acid, mostly contracting second
The combination of one or more of ol dimethacrylate, divinylbenzene.
Preferably, the molecular weight regulator is selected from one or both of n- dodecyl mereaptan, positive stearylmercaptan group
It closes.
Preferably, the initiator is azodiisobutyronitrile.
Preferably, the crosslinking agent is selected from zinc acetate, zinc octoate, o-methoxybenzoic acid, P-methoxybenzoic acid
One or more of combination.
Preferably, the tackifying resin is selected from one or more of terpene resin, rosin resin, Petropols group
It closes.
Preferably, the antioxidant is selected from one of antioxidant 1010, antioxidant 164, antioxidant 1076 or several
Kind combination.
A kind of preparation method of the water proof type foaming hot-fusible pressure-sensitive adhesive for arrangements for automotive doors, comprising the following steps:
S1, mass parts are pressed, by soft monomer 80-92%, hard monomer 1-8%, function monomer 1-4%, molecular weight regulator 0-
1% and initiator 0.1-0.5% is prepared into monomer mixture solution, and monomer mixture solution is divided into two parts；
S2,5-20% monomer mixture solution is added into reaction system, is warming up to 85-90 DEG C, sustained response 1-2h, so
Remaining monomer mixture solution is at the uniform velocity added dropwise in reaction system afterwards, the general reaction time is 6-9h；
S3, after the reaction was completed, crosslinking agent is added into reaction system, insulated and stirred；
S4, if desired tackifying resin, tackifying resin and antioxidant are added into reaction system, if not needing thickening tree
Antioxidant is added into reaction system rouge, insulated and stirred, and preparation is completed, packaging discharging.
The invention has the benefit that
1, the hot-fusible pressure-sensitive adhesive obtained by above-mentioned formula and preparation method not only has preferable peel strength, and
Have at high temperature and hold viscous intensity well, while there is good thermal stability；
2, residual in performed polymer different from conventional solution polymerization process and emulsion polymerization technique using bulk technique
Stay monomer few, polymer product contains admittedly for 100%, solvent-free and moisture evaporation, and product odour is low.
