Abstract
Non-polar adhesive, it relates to Vinyl Acetate Copolymer, polyvinyl acetal and acrylate adhesive.This tackiness agent is that the modified acrylate resin emulsion of forming with Vinyl Acetate Copolymer, polyvinyl acetal thing and acrylic ester emulsion is an adhesive substance, form solvent with acetone, benzene, ethanol, rosin, and interpolation is by the mixed twine mixture of 2,4 diacetylmethanes and isopropenyl acetate composition.Because it can form mechanically link with metal, pottery, and forms the physical chemistry bonding with polarity and non-polar polymeric material, so can be used for bonding polarity or non-polar material.
Description
The present invention relates to tackiness agent, relate in particular to Vinyl Acetate Copolymer, polyvinyl acetal thing and acrylate adhesive.
As everyone knows, tackiness agent is of a great variety and its applicable situation respectively arranged, and polar material bonding normally very easily accomplished, and alternative tackiness agent is a lot.But, for this class non-polar materials such as picture polyethylene, polypropylene, polystyrene, polyester, it is bonding to be extremely difficult, some are considered to the wider polyisobutene glue of the scope of application, F-2 glue, EVA hot melt adhesive, polyurethane adhesive, alpha-cyanoacrylate glue, acrylic polyester glue, organic silica gel etc., when bonding above-mentioned non-polar material, all fail to obtain gratifying effect; Especially to the non-polar material of high-crystallinity, almost there is not bonding effect.The acrylate adhesive of external development has adhesive effect preferably to above-mentioned non-polar material recently, cherish and do not know its component, and price is very expensive.
The present invention's purpose is: to society provide a kind of can not only bonding polar material and also can bonding non-polar material, excellent property, the more honest and cleaner tackiness agent of price.
The present invention realizes above-mentioned purpose like this:
The various tackiness agents of cited tackiness agent before comprising; because wherein as lacking various active group (as: hydroxyl in the material of bonding main composition; amido; cyano group; carboxyl; itrile group; group such as acyl group or amide group); as lacking combining of intensive polar solvent and non-polar solvent in the component of solvent again; so can not make by sticking non-polar material and when contacting, produce effective swelling with tackiness agent; and make bonding main composition molecule infiltrate the non-polar material top layer and form " modification transition layer "; only rely on intermolecular dispersion force between non-polar material and the tackiness agent, so bounding force extremely a little less than.
The preparation principle of non-polar material tackiness agent of the present invention is: 1. described bonding principal constituent of selecting should comprise the various active group; 2. the solvent in the tackiness agent adopts the mixed solvent of being made up of polar solvent and non-polar solvent; 3. add an amount of complexing agent (also can be considered intensive polar solvent).The component of this non-polar adhesive is: the modified acrylate resin emulsion of being made up of polyvinyl acetate emulsion and/or ethene-vinyl acetate copolymer emulsion, polyvinyl acetal thing, acrylic ester emulsion is as adhesive substance, the weight ratio of above-mentioned three kinds of materials is to be advisable with 3: 3: 4, and the weight ratio of the total amount of three kinds of materials in tackiness agent is good with 77～82%.Described mixed twine mixture (also can be considered intensive polar solvent), form by 4～6 carbon atom diketone and isopropenyl acetate, the ratio of the two was advisable with 0.7: 1～1: 0.7 in the mixed twine mixture, and the weight ratio of this mixed twine mixture in gluing is advisable with 8～12%.Described mixed solvent is made up of acetone, benzene or benzene derivative, ethanol, rosin, and the weight ratio of each component was with 6: 4: 5 in solvent: 5 is good, and the weight ratio of solvent in tackiness agent is good with 8～12%.
Described polyvinyl acetal thing is polyvinyl formal, polyvinylacetal, polyvinyl butyral acetal, polyvinyl alcohol contract any one or several polyvinyl acetal thing in urea aldehyde, the polyvinyl alcohol furfural.Described acrylic ester emulsion is third-benzene emulsion, any one or a few acrylic ester emulsion in the esters of acrylic acids such as the third-the third-benzene emulsion, ABS, EVA, MBS, with regard to performance and price and Yan Yongbing-benzene emulsion for suitable.4～6 carbon atom diketone are saturated ketone or beta-unsaturated ketone or cyclic ketones, are the best with 2,4 diacetylmethanes wherein.Described benzene derivative is toluene, dimethylbenzene, monomethylaniline, methyldiphenylamine, phenol etc.
The optimum formula of non-polar adhesive is:
Polyvinyl formal (solid content 9～11%) 24%
Vinyl Acetate Copolymer (solid content 50～55%) 24%
Third-benzene emulsion or the third-the third-benzene emulsion (solid content 36%) 32%
2,4 diacetylmethanes 5%
Isopropenyl acetate 5%
Acetone 3%
Benzene or toluene 2%
Ethanol 2.5%
Rosin 2.5%
Because the resin as bonding composition in this adhesive not only contains vinyl, and contains hydroxyl, carboxyl, carbon back various active group; Diketone and isopropenyl acetate as complexing agent have epistasis, and be wetting to being produced by adhesives by mixed solvent, spread, penetrate into its top layer, and form mechanical bond or by wetting to macromolecular material Swelling, diffusion and the molecular resin that makes the complexing agent molecule reach bonding composition enters the non-polar material top layer, make its top layer become the modified layer of low pole, finish with adhesive physical chemistry and be combined, thereby realize bonding such as metal/metal or brittle substance, metal or brittle substance/non-polar material, non-utmost point material/non-polar material.
This non-polar adhesive not only has adhesive power to materials such as common metal, pottery, polyvinyl chloride, and to being known as macromolecular materials such as being difficult to bonding polyethylene, poly-vinegar, polypropylene, polypropylene, even the higher non-polar material (polypropylene, polystyrene) of degree of crystallinity or foaming non-polar material (such as expanded polystyrene (EPS)) all have good bonding effect, thereby realized the present invention's purpose.
The physical and chemical performance of this adhesive is as follows: dielectric constant 2.3～3.6 presses 1～2kg/cm2, temperature: room temperature～100 ℃, acidproof, alkaline-resisting, hardening time: 8 hours.
