The preparation method of anionic rosin trihydroxymethylpropanyl ester emulsion of the present invention, its preparation process is as follows:
A, in reactor, add rosin, TriMethylolPropane(TMP) and catalyzer E, the weight ratio of TriMethylolPropane(TMP) and rosin is 1.2-1.6:10, the weight ratio of catalyzer E and rosin is 0.1-0.25:100, mixed in 180 ℃ under the protection of nitrogen, then be warmed up to 210 ℃, and be incubated 2 hours and carry out partial esterification reaction, after 2 hours finish, be warmed up to again 250 ℃-255 ℃, and be incubated and within 5-8 hour, carry out esterification, obtain rosin trihydroxymethylpropanyl ester, in insulation, check softening temperature and the acid number whether color of resin is deepened and detected resin after 5 hours;
The auxiliary agent R aqueous solution that the aqueous sodium hydroxide solution that B, formulation content are 50% and content are 30-50%, under agitation condition, the mode that the weight ratio of aqueous sodium hydroxide solution and the auxiliary agent R aqueous solution of take is 1:5 adds the auxiliary agent R aqueous solution to aqueous sodium hydroxide solution, after mixed, stir 60 minutes, reaction finishes rear dropping sodium pyrosulfate, regulates the pH value of mixed solution, makes pH value be controlled at 7-10, use cooling water circulation control temperature of reaction, adjusting temperature is 70 ℃-75 ℃ simultaneously; Adjustment completes, and filters, and obtains anionic polymer rosin emulsifying agent;
C, regulate the temperature of reactor under the condition of 100 ℃-105 ℃, the rosin trihydroxymethylpropanyl ester of the anionic polymer rosin emulsifying agent of B step gained and A step gained be take to the ratio that weight ratio is 1.5-2:10 and to rosin trihydroxymethylpropanyl ester, progressively add anionic polymer rosin emulsifying agent, be uniformly mixed 20 minutes, cool to 97 ℃-100 ℃, add again 90 ℃ of hot soft water to make resin phase inversion, after phase inversion, progressively add 90 ℃ of hot soft water to calculate and adjust emulsion solid content, adjust complete, use cooling water temperature, temperature of cooling water and the still temperature temperature difference are no more than 30 ℃, obtain anionic rosin trihydroxymethylpropanyl ester emulsion.
In technique scheme, scheme is more specifically: described catalyzer E is esterifying catalyst, and described esterifying catalyst is one or more the mixture in phosphoric acid, Hypophosporous Acid, 50, calcium propionate, calcium hydroxide, calcium acetate, Quilonum Retard, zinc oxide and magnesium oxide; Described auxiliary agent R is polymeric surface active agent, and described polymeric surface active agent is one or more the mixture in Styrene And Chloroalkyl Acrylates salt copolymer, methacrylic acid Soxylat A 25-7-acrylate multipolymer, methyl thiazolinyl polyethenoxy ether, isopentene group polyethers, poly glycol monomethyl ether (CH3O (CH2CH2O) nH) and allyl polyethenoxy ether (CH2=CHCH2O (CH2CH2O) nH).
Owing to adopting technique scheme, the present invention has following beneficial effect:
Because the present invention be take rosin and TriMethylolPropane(TMP) prepare anionic rosin trihydroxymethylpropanyl ester emulsion with the emulsification of anionic polymer rosin emulsifying agent after raw material is carried out esterification, make product emulsion foaminess little, large to hard water and temperature tolerance, be difficult for cohesion, micelle is little, and coating is stable; Use compared with the rosin trihydroxymethylpropanyl ester of high softening-point as basic resin, make emulsion keep the good viscous force of holding when increasing substantially the initial bonding strength of tackiness agent and peeling force, the rosin milk that has solved original adhesive industry can not be taken into account the shortcoming of each performance index.
