The mol ratio of the polyvalent alcohol that preferably, in the present invention used and terminal hydroxy group diolefine oligopolymer is 0~2: 1.In actual mechanical process, can adjust according to the performance requriements of the molecular weight of terminal hydroxy group diolefine oligopolymer and prepared PUA type reaction resin: if the molecular weight of the terminal hydroxy group diolefine oligopolymer using is little, or the viscosity of required PUA type reaction resin is little, the consumption of polyvalent alcohol can reduce in right amount, does not even use.If the molecular weight of the terminal hydroxy group diolefine oligopolymer using is large, or the viscosity of required PUA type reaction resin is large, and the consumption of polyvalent alcohol just needs appropriate increasing, and makes the mol ratio of polyvalent alcohol and terminal hydroxy group diolefine oligopolymer reach 2.If but the consumption of polyvalent alcohol is too much, such as the mol ratio of polyvalent alcohol and terminal hydroxy group diolefine oligopolymer is greater than 2, hard section of the PUA resin of gained too many, it is large that water-intake rate becomes, viscosity is excessive.Preferably, the mol ratio of polyvalent alcohol and terminal hydroxy group diolefine oligopolymer is 1: 10~2: 1.
Polyvalent alcohol can adopt separately dibasic alcohol or trivalent alcohol in the present invention, also dibasic alcohol and trivalent alcohol can be used in conjunction with.While using dibasic alcohol, diatomic alcohol compounds and di-isocyanate reaction, what obtain is the resin of linear structure, while using trivalent alcohol, trivalent alcohol and di-isocyanate reaction, can obtain the resin of one or many branching, the degree of branching of molecule and end number are relevant with the ratio of functional groups of polyreaction, also relevant with the level of response of functional group.In theory, if only contain a trivalent alcohol unit on a molecular resin, once, molecular resin has three end groups to a molecular resin branching; If molecular resin contains two trivalent alcohols, molecular resin branching twice, molecular resin has four end groups.The end group of reaction resin of the present invention is reactive group, and end group is more, and the activity of resin is higher, but end group is more, and in resin, the content of the hard section of double carbamate is also more, and the viscosity of resin is also larger.Although simpler in theory with the resin of synthetic four chain ends of tetravalent alcohol, the polarity of small molecules tetravalent alcohol is large, poor with the consistency of terminal hydroxy group diolefine oligopolymer, solvability is little.So preferably adopt in the present invention dibasic alcohol and trivalent alcohol.
Preferably, above-mentioned polyvalent alcohol can comprise dibasic alcohol and trivalent alcohol simultaneously, and wherein the mol ratio of dibasic alcohol and terminal hydroxy group diolefine oligopolymer is 0~2: 1, and the ratio of the integral molar quantity of the molar weight of trivalent alcohol and dibasic alcohol and terminal hydroxy group diolefine oligopolymer is 0~2: 1.The mol ratio of dibasic alcohol, trivalent alcohol and terminal hydroxy group diolefine oligopolymer is controlled in above-mentioned scope, be conducive to form the PUA type reaction resin that soft section of diolefine oligopolymer in each molecule is 1-5,2-6 of the hard section of double carbamate, (methyl) acryloyl-oxy group molecule chain end 2-4, and then obtain the good PUA resin type of over-all properties reaction resin.

In a kind of embodiment of the present invention, the diisocyanate cpd of preparing above-mentioned PUA type reaction resin is aliphatic diisocyanate chemical combination or aromatic diisocyanate cpd.Particularly, diisocyanate cpd includes but not limited to tolylene diisocyanate (TDI), isophorone diisocyanate (IPDI), hexamethylene diisocyanate (HDI), dimethylbenzene alkane two isocyanic acids (MDI) and hydrogenation TDI, hydrogenation MD etc. in the present invention.
Can select the type of used diisocyanate cpd according to the performance of required PUA type reaction resin.For example, if need the reaction resin that intensity is high, can select aromatic TDI and MDI; If need yellowing resistance good, the reaction resin that viscosity is less, can select aliphatic IPDI, HDI and hydrogenation TDI, hydrogenation MD.
In the process of preparation PUA type reaction resin of the present invention, in diisocyanate cpd-in NCO functional group and polyvalent alcohol and terminal hydroxy group diolefine oligopolymer total-mol ratio of OH functional group determines the molecular weight of resin, also affect the viscosity of resin, both proportionings more approach equal proportion, the molecular weight of resin is higher, and viscosity is larger.To the reaction resin of linear structure, diisocyanate cpd-NCO group number than diolefine and polyvalent alcohol total-many two of OH group number; To the resin of three chain ends, diisocyanate cpd-NCO group is than many three of-OH group, similarly, containing the resin of four chain ends, diisocyanate cpd-NCO group is than many four of-OH group, and additional-NCO group is for linking (methyl) acrylate of contain-OH group.Preferably, diisocyanate cpd-NCO functional group and polyvalent alcohol and terminal hydroxy group diolefine oligopolymer total-mol ratio of OH group is 6: 5~2: 1.
In a kind of embodiment of the present invention, be used for the end group-NCO radical reaction with preform, (methyl) acrylate of the contain-OH group of preparation PUA type reaction resin, includes but not limited to hydroxyethyl methylacrylate (HEMA), Rocryl 410 (HPMA), Hydroxyethyl acrylate (HEA) and Propylene glycol monoacrylate (HPA).Their consumption if can ensure by work in-process resin-NCO group total overall reaction is complete.
The preparation method that a kind of PUA type reaction resin is also provided in the present invention, comprises the following steps: react with diisocyanate cpd and generate the preform of end group as-NCO taking terminal hydroxy group diolefine oligopolymer, polyvalent alcohol; React with preform and generate sold resin with (methyl) acrylate of contain-OH.
Preferably, in the method for above-mentioned PUA type reaction resin, prepare end group and be-a kind of concrete steps of the preform of NCO comprise: the terminal hydroxy group diolefine oligopolymer after decompression dehydration is mixed to formation solution A with optional polyvalent alcohol and optional catalyzer heated and stirred; In solution A, add diisocyanate cpd, the temperature that raises is gradually to higher than 70 DEG C, and reaction 1~2.5h obtains end group and is-preform of NCO.
In the process of this PUA type reaction resin of preparation, because hydroxyl is almost irreversible with reacting of isocyanate groups, once reaction between functional group, just form the fixing order of connection, so, obtain specific soft, the hard section of molecular chain of mode in succession, the raw material reacting will add sequentially.The chemically reactive of the two-NCO reactive group of vulcabond is relevant with joined group, for example, in tolylene diisocyanate (TDI) and two different Buddhist diketone vulcabond (IPDI), the active difference of two-NCO reactive group is very large, can utilize the order of addition(of ingredients) of this chemically active difference and raw material, make soft, hard section to connect according to certain arrangement mode, to be prepared with the PUA molecule of specific soft, hard section sequence.
With reference to aforesaid PUA resin chemical equation, if first reacted with butyleneglycol and vulcabond, and then add the reaction of terminal hydroxy group diolefine oligopolymer to generate the preform of NCO end-blocking, finally add the feed way of (methyl) acrylate of contain-OH, because vulcabond in the reaction of butyleneglycol and vulcabond is excessive, the possibility that forms the polymer of butyleneglycol and vulcabond just significantly reduces, most product is that the two ends of butyleneglycol connect upper isocyanic ester, the terminal hydroxy group diolefine oligopolymer adding subsequently by with isocyanic ester on the two ends of butyleneglycol and reaction system in remaining di-isocyanate reaction, comprise two soft section as represented in front formula will be made, the molecule chain end of two methacryloxy groups and the product content of three hard segment structures maximize.
In the preparation process of aforementioned PUA type reaction resin, step-reaction polymerization is to carry out between hydroxyl and isocyanic ester, so can there is reacting of various ways between raw material and raw material, therefore, the molecular weight of reaction product and chemical constitution are not single, except the represented molecular structure of above formula, also may there is the molecule of part resin to be formed by soft section of diolefine oligopolymer and di-isocyanate reaction completely, also may there is a small amount of molecule to be formed by butyleneglycol and two di-isocyanate reactions completely, but the represented product structure of above-mentioned chemical equation is the component of content maximum in reaction product.Carry out molecular chain structure when design of PUA type reaction resin, taking the product structure of this maximum distribution as corresponding resin structure.About the detailed knowledge of step-reaction polymerization and reaction product, can be referring to the books of polymer chemistry.
In order to control branched structure and the viscosity of resin, in the time using optional polyvalent alcohol to adjust the performance of PUA, preferably, allow polyvalent alcohol first react with diisocyanate cpd, and then add terminal hydroxy group diolefine oligopolymer further to react, generate end group and be-preform of NCO.Such feed way, react time-NCO group with diisocyanate cpd because polyvalent alcohol is first excessive, can suppress the polymerization of polyvalent alcohol and diisocyanate cpd, and the structure of main generation-NCO group end capping, adding after terminal hydroxy group diolefine oligopolymer, polyvalent alcohol just can be distributed on molecular resin chain dispersedly, generates controlled branched structure.
Preferably, in the method for above-mentioned PUA type reaction resin, prepare end group and be-a kind of concrete steps of the preform of NCO comprise: diisocyanate cpd mixed with optional polyvalent alcohol, temperature is not higher than stirring reaction 0.5~2h at 70 DEG C, form solution B, in solution B, add terminal hydroxy group diolefine oligopolymer after decompression dehydration and optional catalyzer, control temperature to not higher than 70 DEG C of stirring reaction 1~2.5h, obtain end group and be-preform of NCO.
