Spray Cotton Binder with High Elasticity
Technical field
The present invention relates to a kind of Spray Cotton Binder with High Elasticity, specifically refer to when be used for gum sprayed cotton makes fiber is risen the sticker of cohesive action, belong to the adhesive technology field.
Background technology
Gum sprayed cotton has been widely applied to the every aspect of people's life, and articles for use do not stay the figure of its existence nowhere to insulation garment or the like from the bed.Yet when same gum sprayed cotton is applied to different field, the requirement of its quality especially pliability is differed widely, the gum sprayed cotton of for example using as mattress is exactly to possess hardness sense high resilience again as much as possible to its requirement.Gum sprayed cotton whether possess hardness, be crucial as the resin structure of the spray celloidin of fiber caking agent, the spray celloidin that uses soft resin to make not only possesses the hardness sense but also whippy gum sprayed cotton comes in any case also can not do.
Summary of the invention
The present invention discloses a kind of Spray Cotton Binder with High Elasticity, is the main structure resin with rigid TEB 3K, vinylbenzene, cooperates fiber species to select, and making the gum sprayed cotton of processing is that the sense of tool hardness has good elasticity again.
The technical scheme that the present invention adopts is: Spray Cotton Binder with High Elasticity is made up of resin component, polymerization crosslinking component, emulsifying additive component; Resin Composition is made up of TEB 3K, vinylbenzene, vinyl cyanide, ethyl propenoate, Bing Xisuandingzhi, methylene-succinic acid; The polymerization crosslinking component is made up of N hydroxymethyl acrylamide, Potassium Persulphate; The emulsifying additive component is made up of X 2073,0S-15, and carrier component adopts deionized water.
Building-up process adopts emulsion polymerization technique and redox-catalyst system; With adding part deionized water, linking agent, emulsifying agent and resin monomer earlier; After the seed emulsion preparation; Drip surplus material by the technical requirements program, the discharging filtration is finished product behind stirring, intensification, insulation, cooling, the adjustment pH value.
The invention has the beneficial effects as follows: cooperate the selection of fiber species, the gum sprayed cotton that the spray celloidin of employing present technique is processed, product hardness is high, and rebound resilience is strong, and perviousness is big, water-tolerant.
Embodiment:
By weight percentage, the TEB 3K 25.5% of resin Composition, vinylbenzene 20.3%, vinyl cyanide 15.8%, ethyl propenoate 13.2%, Bing Xisuandingzhi 13.2%, methylene-succinic acid 12%; The N hydroxymethyl acrylamide 82% of polymerization crosslinking component, Potassium Persulphate 18%; The X 2073 62% of emulsification, binder component, 0S-15 are 38%; The sodium hydrogencarbonate of other additives is 0.1 ~ 0.5% of total component.Total ingredient proportion adopts resin Composition 40%, carrier component 60%, and emulsification, binder component are by 2.5% of total amount, and the polymerization crosslinking component is by 1.5 ~ 2% of total amount.
When practical implementation was synthesized, elder generation was with the mixed solution of deionized water, OS-15 and part Potassium Persulphate, 30% the TEB 3K and the mixed solution of other resin monomers; Drop in the reactor drum, adding an amount of Sodium phosphate, dibasic or sodium hydrogencarbonate adjusting pH value is about 6, when slowly being warmed up to 65 ℃; Insulation reaction for some time, make polymeric solution form seed emulsion after, begin to drip remaining 70% resin monomer mixed solution; And dripping the mixing solutions of Potassium Persulphate, N hydroxymethyl acrylamide continuously, the mixing solutions in that 3-4h adds resin monomer mixed solution and Potassium Persulphate, N hydroxymethyl acrylamide synchronously is warmed up to 80 ℃ then; Insulation reaction 1h is warmed up to 90 ℃ again, insulation 30min; Cool to then below 50 ℃, adjust pH is 6 ~ 7, and the after-filtration that cools is a finished product.
