Description

The preparation method of anionic rosin trihydroxymethylpropanyl ester emulsion
Technical field
The present invention relates to chemical technology field, especially a kind of preparation method of anionic rosin trihydroxymethylpropanyl ester emulsion.
Background technology
Leading status is being captured in rosin production and the rosin deep processing of China in the world always, flourish along with the Gum Rosin industry, the various product of Gum Rosin has been widely used in the industries such as tackiness agent, coating, papermaking, printing ink, rubber, batik, food.But because the tempo of recent domestic petroleum resin is very fast, be subjected to seasonal effect less due to the starting material of petroleum resin sources again, acquisition cost is relatively low, causes petroleum resin to have larger advantage on price, thereby has impacted original market of Gum Rosin.In recent years again at a time when world economy depressed makes rosin deep processing industry be subject to a certain extent strike.But we have also seen the advantage place of Gum Rosin, and from overall performance, Gum Rosin is used more extensive than petroleum resin, and effect is more superior.The raw material sources of Gum Rosin are in renewable resources rosin, but China's pine tree resin tapping amount only reaches 50% of existing pine tree resin tapping amount at present, the relatively day by day exhausted more aobvious advantage of petroleum resources.From the long term growth prospect, rosin and deep processing industry thereof meet the ambitious goal of Sustainable development, more have good development prospect.
Market of Adhesives both domestic and external relates to the packing of pencil, books customized, and furniture bonding, all tackiness agent are all lived closely bound uply with us basically, are directly connected to our health.And inflammable, explosive, volatile, the toxic solvents such as the containing benezene that existing tackiness agent has, ester class, ketone, and the rosin milk of tackiness agent can not take into account each performance index, and foaming is large, little to hard water and temperature tolerance, easily cohesion, micelle is large, is coated with unstable.
Summary of the invention
The invention provides a kind of preparation method of anionic rosin trihydroxymethylpropanyl ester emulsion, it can solve existing rosin milk can not take into account each performance index, and foaming is large, little to hard water and temperature tolerance, easily cohesion, micelle is large, is coated with unsettled problem.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
The preparation method of anionic rosin trihydroxymethylpropanyl ester emulsion of the present invention, its preparation process is as follows:
A, add rosin, TriMethylolPropane(TMP) and catalyzer E in reactor, 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 the partial esterification reaction, be warmed up to again 250 ℃-255 ℃ after 2 hours finish, and be incubated 5-8 hour and carry out esterification, namely obtain the rosin trihydroxymethylpropanyl ester, check in insulation softening temperature and the acid number whether color of resin is deepened and detected resin after 5 hours;
B, formulation content are the auxiliary agent R aqueous solution that 50% aqueous sodium hydroxide solution and content are 30-50%, under agitation condition, mode take the weight ratio of aqueous sodium hydroxide solution and the auxiliary agent R aqueous solution as 1:5 adds the auxiliary agent R aqueous solution to aqueous sodium hydroxide solution, mixed complete rear stirring 60 minutes, drip sodium pyrosulfate after reaction finishes, regulate the pH value of mixed solution, make pH value be controlled at 7-10, use simultaneously cooling water circulation control temperature of reaction, adjusting temperature is 70 ℃-75 ℃; Adjustment is completed, and filters, and obtains anionic polymer rosin emulsifying agent;
C, the temperature of conditioned reaction still is under the condition of 100 ℃-105 ℃, the anionic polymer rosin emulsifying agent of B step gained and the ratio of rosin trihydroxymethylpropanyl ester take weight ratio as 1.5-2:10 of A step gained are progressively added anionic polymer rosin emulsifying agent to the rosin trihydroxymethylpropanyl ester, mix 20 minutes, cool to 97 ℃-100 ℃, add again 90 ℃ of hot soft water to make the resin phase inversion, progressively add 90 ℃ of hot soft water to calculate after phase inversion 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 ℃, namely get 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 prepares anionic rosin trihydroxymethylpropanyl ester emulsion with the emulsification of anionic polymer rosin emulsifying agent take rosin and TriMethylolPropane(TMP) after raw material carries out esterification, make the product emulsion foaminess little, large to hard water and temperature tolerance, be difficult for cohesion, micelle is little, and coating is stable; Use than the rosin trihydroxymethylpropanyl ester of high softening-point as basic resin, make emulsion keep the good viscous force of holding in the initial bonding strength that increases substantially 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.
