Description
Technical field
The invention belongs to chemical technology field, especially relate to special-purpose polyurethane slurry of a kind of velcro and preparation method thereof.
Background technology
The special-purpose polyurethane slurry of velcro generally all is to adopt two component conventional polyurethanes tackiness agent, promptly 101 glue substitute, need solidify 24 hours at 45 ℃ ± 1 ℃ thermostatic chamber, could carry out aftertreatment-itemize to hasp, scrape button, because set time is long, the conditional request harshness, cause the technical process of production hasp producer long, power consumption is big, efficient is low, cost is low, not environmental protection, does not reach export standard, is eliminated gradually.
Summary of the invention
The objective of the invention is to improve the deficiency of prior art and provide a kind of set time short, tensile strength is high, water-fastly, alkaline-resisting wash that performance is strong, tough and tensile straight and upright, the special-purpose polyurethane slurry of velcro that the fresh-keeping degree of color and luster is high of environmental protection, feel and preparation method thereof.
The object of the present invention is achieved like this, a kind of polyurethane slurry for hasp, and the general molecular formula of this polyurethane slurry is:
R is not for containing the alkyl of aromatic proton in the formula.
A kind of preparation method of above-mentioned polyurethane slurry, be characterized in that this method is is that 0.2-0.25 part molecular weight is 2000 ± 200 polyester polyol by equivalent part, 0.26-0.96 part terylene level ethylene glycol, 0-0.11 1.4 butyleneglycols or 1.3 butyleneglycols of part, 0-0.007 the TriMethylolPropane(TMP) of part, the tolylene diisocyanate chemical combination of 0.625-1.2 part forms.
Be that bottoming solvent, other reactants except that tolylene diisocyanate are dropped in reactors, stir, seal then, be warming up to 60-65 ℃, slowly drip tolylene diisocyanate, titration in 2-3 hour, 70-90 ℃ of insulation reaction added catalyzer after 3 hours, reacted 40-120 minute again, cooling adds letdown solvent dun, stir, with being coated with 4# cup viscosimetric 30-80S under 25 ℃ of temperature, qualified back adds additive, get the material package dress at 35-40 ℃, bottoming solvent and letdown solvent dun are collectively referred to as total solvent.
The bottoming solvent is made up of grade oil toluene that accounts for total solvent 2%-20% and the N.N dimethyl formamide that accounts for the 4%-15% of total solvent.
Letdown solvent dun is by N, N dimethyl formamide, N, N N,N-DIMETHYLACETAMIDE, pimelinketone, butanone, three kinds and above mixing in acetone, toluene, dimethylbenzene, vinyl acetic monomer, N-BUTYL ACETATE, the methylal.
Catalyzer is can be a kind of or any mixing in organotin, the organic amine.。
Catalyzer can be 4-methyl hexamethylene diamine, Tetramethyl Ethylene Diamine, compound tertiary amine, triethylene diamine, N-methylmorpholine, 1.4-dimethyl benzylamine, the 4-methyl-diaminopropane in the stannous octoate, dibutyl tin laurate, organic amine in the organotin.
Additive is that in the glycols of V-6 fire retardant, composite flame-retardant agent, fire-retardant silicone oil L-570, L-620, low-carbon (LC) one or more are mixed.。
When adding additive, add stablizer.
Stablizer is one or more mixing in the ultraviolet (UV) of anti-xanthochromia the-R, UV326/327, high-efficiency anti-oxidant 1008C, the phosphoric acid ester.
Compared with the prior art the present invention has following distinguishing feature and positively effect: the present invention adopts polyester polyol, terylene level ethylene glycol, 1.4 butyleneglycols, tolylene diisocyanate, TriMethylolPropane(TMP) reaction to synthesize, and can get the different length molecular chain of different end group polymkeric substance down in different mol ratio (or equivalent):
(1)+(2) or other polyol further react and generate high molecular urethane resin.For example:
If press
In the structural formula R for the alkyl that does not contain aromatic proton adds by a certain percentage again low charcoal dibasic alcohol, as chain extension again just such as ethylene glycol, propylene glycol, 1.3 butyleneglycols, 1.4 butyleneglycols, neopentyl glycol, forms higher high molecular polymer or than hanging down superpolymer.The present invention utilizes this reaction rule exactly, in conjunction with the velcro performance requriements, the common polyurethane resin structure is carried out modification, makes in its urethane resin structure soft section and a hard section chain link be suitable for the velcro performance requriements and designs.
So-called soft section be by the polyester polyol of molecular weight 2000 ± 200 and polyisocyanates-the NCO radical reaction forms, hard section then is by low-carbon (LC) dibasic alcohol and di-isocyanate reaction generation.
