Abstract
The present invention carries out free radical grafting copolymerization with Chlorinated Polypropylene III and vinyl cyanide, acrylate and obtains in solution, polyolefine (polypropylene, polyethylene etc.) is had the novel adhesive of the ability of gluing than strong rubber.Can reach 55kg/cm to the gluing shearing resistance of polypropylene-polypropylene
2, also be used for polypropylene-steel, bonding between polypropylene-aluminium and the above-mentioned metal.Be characterized in that the reaction times short, technology is simple, and product does not need can directly use through separation and purification.
Description
The invention provides and carry out free radical grafting copolymerization by Chlorinated Polypropylene III and acrylate, vinyl cyanide and close reaction, preparation has the method for the tackiness agent of strong bonding strength to polyolefin polymers material and goods thereof.The tackiness agent that is provided is nonpolar, difficult bonding polypropylene material (as sheet material, finished product, film etc.) to the surface, has good adhesive effect.To other materials such as metal, rubber, leather, synthetic leather, timber, good cementability is arranged also simultaneously.Also can be used as coating and metal oil resistant tectum.It is a kind of range of application novel adhesive comparatively widely.
Polypropylene is that production is bigger at present, uses one of wider general-purpose plastics.But owing to do not have polar group in the polypropylene molecule, the material surface adsorptive power is very poor, and surface tension is little, and being difficult to find can wetting its surperficial tackiness agent.In addition, because polyacrylic fusing point is than higher, melting solder is difficulty relatively, be dissolved in any solvent at normal temperatures again hardly, this just gives the bonding of polypropylene material itself and polypropylene material and other material, brings a lot of difficulties, has limited the broadened application of acrylic plastering to a certain extent.Only find that so far Chlorinated Polypropylene III has reasonable cementability to polypropylene.
Chlorinated Polypropylene III has good ageing-resistant, anti-combustion, performance such as corrosion-resistant, can be dissolved in benzene,toluene,xylene, the tetracol phenixin equal solvent.When chlorinated polypropylene solution and polypropylene material connect when melting, polypropylene surface generation limited swelling, crystallizing field in polypropylene surface and the Chlorinated Polypropylene III, power attracts mutually between polypropylene surface is with the crystallization of identical chemical structure crystalline, thereby demonstrates Chlorinated Polypropylene III to polyacrylic cementability.Usually the chlorinity that is used as the Chlorinated Polypropylene III of tackiness agent is 20-40%.At this moment, the original very high polypropylene of degree of crystallinity, after introducing the chlorine atom and forming Chlorinated Polypropylene III, the crystallization of Chlorinated Polypropylene III is reduced to below 40%.Therefore Chlorinated Polypropylene III has that fusing point (softening temperature) is lower, the characteristics of Yi Rong, and the physical strength of polymkeric substance also reduces because of force of cohesion reduces correspondingly.With the bonding polypropylene material of Chlorinated Polypropylene III, when stressed, the destruction between the glue-line is often taken place.Therefore chlorinated polypropylene adhesive is mainly used in polypropylene film, the hot melt adhesion of the printing-ink of polypropylene articles, coating and two-way drawing-off polypropylene film etc.
In order to improve the force of cohesion of Chlorinated Polypropylene III, people once utilized the activity of chlorine atom in the Chlorinated Polypropylene III, Chlorinated Polypropylene III is connect technological transformation, in polymer molecule, introduce the compound that has polar group, to strengthen the physical strength of Chlorinated Polypropylene III, increase the adhesiveproperties of Chlorinated Polypropylene III to other materials simultaneously, used according to reports grafted monomer has unsaturated carboxylic acid compounds such as esters of acrylic acid, maleic anhydride.And obtained certain effect, main as the poly-third material coating, printing ink, anti-corrosion of metal tectum etc.
It is grafted monomer that the present invention adopts the vinyl cyanide have strong polar group, and introduces a certain amount of esters of acrylic acid unsaturated organic compound, uses the force of cohesion that strengthens polymkeric substance and to the adhesiveproperties of other material, has obtained significant effect.
It is 2-10 ten thousand that the present invention adopts the Chlorinated Polypropylene III molecular weight.Be the polypropylene chlorination in tetracol phenixin with harmonic component, or make that chlorinity is controlled at 30-40% at the aqueous phase suspension chlorination.Then Chlorinated Polypropylene III is dissolved in the solvent, obtains the chlorinated polypropylene solution of proper viscosity, add a certain amount of grafted monomer again, under the initiation of organo-peroxide, free radical grafting copolymerization takes place close reaction.Because Chlorinated Polypropylene III, monomer, solvent can be miscible well,, form Chlorinated Polypropylene III-acrylic ester-acrylonitrile graft copolymer in homogeneous phase so reaction is to carry out rapidly.This grafted chlorinated polypropylene multipolymer through modification to difficult clay soil/polyolefin base polymer materials such as polypropylene, has stronger bonding force, and we are referred to as polyolefin adhesive to it.
Main grafted monomer of the present invention is an acrylate, second grafted monomer be acrylonitrile compound (
R=C
4-C
8).Used raw material and proportioning are as follows:
Chlorinated Polypropylene III: monomer=100: the 1-10(weight ratio)
Monomeric proportioning is:
Vinyl cyanide: acrylate=1: the 1-3(mol ratio)
Organo-peroxide is a peroxidation di-t-butyl, and consumption is 0.1-0.5%, and solvent is toluene, dimethylbenzene etc.
Be reflected under the nitrogen protection and carry out, temperature of reaction is 110-120 ℃, and the reaction times is 3 hours.
Polyolefine glue jelly provided by the present invention except that polyolefins (polypropylene, polyethylene etc.) polymer materials, finished product, film etc. being had stronger adhesiveproperties, also has good cementability to other material.Bonding as metals such as polypropylene and steel, aluminium, metallic substance such as steel, aluminium itself bonding, polypropylene, polyethylene film and paper bonding, and leather, rubber, synthetic leather is bonding or the like.Can reach 55kg/cm to polypropylene-polyacrylic adhesive shear strength

Preparation method of the present invention and the available following example explanation of enforcement:
The preparation of preparation method's 1 Chlorinated Polypropylene III-butyl acrylate-acrylonitrile graft copolymer (polyolefin adhesive CT-12)
In 1000 milliliters of three-necked bottles of electric mixer, reflux condensing tube and dropping funnel are housed, add Chlorinated Polypropylene III 100 grams and dimethylbenzene 280 grams, rise moving the stirring, dissolving gradually under heating.In addition, adding in dropping liquid liquid funnel by butyl acrylate and vinyl cyanide mol ratio is 3: 1 mixed solution 1 gram, 20 milliliters of dimethylbenzene and peroxidation di-t-butyl 0.4 gram.
When reactor temperature rises to 80 ℃, under the stirring that keeps, progressively be added dropwise to the mixed solution of butyl acrylate and vinyl cyanide, in 20 minutes, dropwise.Slowly be warming up to 110-120 ℃ then, back flow reaction 2.5-3 hour, then get polyolefin adhesive CT-12, product is a light yellow viscous liquid.
