Abstract
The invention provides white latex taking improved polyvinyl acetal adhesive as binder, which is widely applied to the bonding of woodware, plywood, cloth and leather materials and the painting of wall surface. The white latex is mainly composed of the following raw materials in parts by weight: 80-88 of improved polyvinyl acetal adhesive, 5-10 of ethylene glycol, 0.5-1.0 of glycerine, 0.1-0.3 of tribromophenyl, 0.2-0.3 of mould proof fungicide, 0.1-0.3 of softening agent, 0.5-0.8 of thickening agent, 0.1-0.2 of defoaming agent and 4-6 of water. In the preparation method, firstly, defoaming agent is added to water, after the defoaming agent is dissolved, other raw materials are added to stir and mix for 30-60 min to obtain the product. The invention has low preparation cost, short preparation period, low energy consumption, strong water resistance and low temperature resistance.
Description
(1) technical field: the invention belongs to a kind of aqueous binder, specifically be can be widely used in material adhesives such as woodenware, glued board, cloth, leather with and a kind of of metope brushing be the white glue with vinyl that sizing is made with the modified version JSF.
(2) background technology: the production of traditional white glue with vinyl is raw material with the vinyl acetate mainly, is scattered in aqueous phase under the effect of polyvinyl alcohol, under certain temperature condition, forms through the ammonium persulphate initiated polymerization.Its production cycle is grown (about 16 hours), product cost is higher, and only the polyvinyl alcohol price just reaches more than per ton ten thousand yuan at present, needs the steam heating energy consumption big simultaneously in the preparation process, product water tolerance and lower temperature resistance are relatively poor, bring inconvenience for manufacturing enterprise and user.
(3) summary of the invention: purpose of the present invention is exactly that a kind of cost that proposes at existing problem in the existing white glue with vinyl production process is lower, with short production cycle, and less energy-consumption has a kind of white glue with vinyl better water-fast, resistance to low temperature.
The present invention is made up of the raw material of following weight parts:
Modified version JSF 80-88 ethylene glycol 5-10
Glycerol 0.5-1.0 vinylformic acid three bromo-ester 0.1-0.3
Antimildew disinfectant 0.2-0.3 softening agent 0.1-0.3
Thickening material 0.5-0.8 defoamer 0.1-0.2
Water 4-6
During preparation, elder generation adds defoamer in the entry dissolves, and adds the modified version JSF again, stirs 10-15 minute, adds other raw materials more respectively, stirs to get final product in 30-60 minute.The modified version JSF of using in the above-mentioned prescription (trade(brand)name 107 glue) is that condensation in acidic medium forms by polyvinyl alcohol resin and formaldehyde, be mainly used in industries such as civil construction, printing bookbinding, materials processing, label stickup, coating manufacturing, be used for replacing the vinyl acetate and the polyvinyl alcohol of traditional white glue with vinyl prescription in the present invention as main raw material-tackiness agent, made white glue with vinyl cost is reduced greatly; Simultaneously, can shorten life cycle of the product greatly, make product and only need 1-2 hour from being dosed into, whole process of preparation need not heating all reaction, not consumes energy at normal temperatures.Made product is under the identical situation of other performances, and water-fast, resistance to low temperature obviously improves.
White glue with vinyl of the present invention, its key technical indexes is as follows:
1. outward appearance: oyster white thick glue liquid
2. solid content: 30 ± 2%
3. viscosity: 2500-7000 centipoise
4.PH value: 6-8
5. bonding strength of wood: 〉=90kg/cm

(4) embodiment:
Embodiment 1: cancellation infusion 0.2kg adds in the 4kg water, after the stirring and dissolving, get 107 glue 80kg again, add to wherein, stirred 10-15 minute, add antimildew disinfectant 0.2kg, softening agent 0.1kg, ethylene glycol 5kg, glycerol 0.5kg, vinylformic acid three bromo-ester 0.1kg, thickening material 0.5kg respectively, mixed 30-60 minute, promptly.
Embodiment 2: cancellation infusion 0.1kg adds in the 6kg water, after the stirring and dissolving, get 107 glue 88kg again, add to wherein, stirred 10-15 minute, add antimildew disinfectant 0.3kg, softening agent 0.3kg, ethylene glycol 10kg, glycerol 1.0kg, vinylformic acid three bromo-ester 0.3kg, thickening material 0.8kg respectively, mixed 30-60 minute, promptly.
Above-mentioned defoamer generally uses X-202 emulsion paint defoamer, antimildew disinfectant YL-3, thickening material PN.
Claims (1)
1. one kind is the white glue with vinyl that sizing is made with the modified version JSF, it is characterized in that being made up of the raw material of following weight parts:
Modified version JSF 80-88 ethylene glycol 5-10
Glycerol 0.5-1.0 vinylformic acid three bromo-ester 0.1-0.3
Antimildew disinfectant 0.2-0.3 softening agent 0.1-0.3
Thickening material 0.5-0.8 defoamer 0.1-0.2
Water 4-6.
