Abstract
The invention discloses a white latex which does not gel at low temperature which is suitable to be used at low temperature. The invention is characterized in that the white latex takes vinyl acetate as the main raw material, and auxiliary materials, such as polyving akohol, formaldehyde and the like are added to obtain the white latex. The white latex has the characteristics of no gelling at low temperature, favourable workability and high low-temperature strength.
Description
Technical field
The invention describes a kind of white glue with vinyl that can use at low temperatures, belong to the chemical industry adhesive area.
Background technology
White glue with vinyl is a kind of tackiness agent that is obtained by the vinyl acetate between to for plastic polyisocyanate polyaddition, is widely used in the bonding of timber, paper etc., but during low temperature because gel and viscosity increases influences workability and final adhesive effect greatly.
The purpose of this invention is to provide under a kind of low temperature also the not white glue with vinyl of gel, be adapted at using under the low temperature environment.
Summary of the invention
White glue with vinyl of the present invention is to be main raw material by vinyl acetate, adds auxiliary materials such as polyvinyl alcohol and formaldehyde and obtains.
The weight proportion of various compositions is as follows in the latex of the present invention:
Vinyl acetate 700-900g
Polyvinyl alcohol 80-120g
Formaldehyde (37% content) 40-50g
Hydrochloric acid (concentration 10%) 10-11g
Sodium hydroxide 10-12g
Emulsifying agent 8-12g
Sodium bicarbonate 23g
Potassium Persulphate 2g
Dibutyl phthalate 100g
Water 1000-1200g
Compound method of the present invention is as follows:
The water and the polyvinyl alcohol that in having the reactor of whipping appts, add half, about 90 ℃ of intensification, stirring is dissolved polyvinyl alcohol fully, adds formaldehyde, stirs 15 minutes, adds hydrochloric acid again, and reaction is 1 hour under 70-80 ℃ temperature.Use sodium hydroxide conditioned reaction liquid pH value to 8-9 then, add remaining water again, stir, obtain yellow translucent liquid.
Continue to add emulsifying agent, stir and make it to mix, heat temperature raising to 60 ℃ slowly adds vinyl acetate and Potassium Persulphate then, and insulation refluxes.Feed rate is controlled at and added in 6 hours.Be warming up to 90 ℃ then, insulation reaction 1 hour.Be cooled to below 50 ℃, add pre-configured sodium bicarbonate and dibutyl phthalate mixed solution.Further mix, discharging obtains the latex finished product.
Specific implementation method
Further specify the present invention by the following examples, protection domain of the present invention is not limited in embodiment certainly.
Embodiment:
The water and the 100g polyvinyl alcohol that in having the reactor of whipping appts, add 550g, about 90 ℃ of intensification, stirring is dissolved polyvinyl alcohol fully, adds 40g formaldehyde, stirs 15 minutes, adds 10g hydrochloric acid again, and reaction is 1 hour under 70-80 ℃ temperature.Use sodium hydroxide conditioned reaction liquid pH value to 8-9 then, add 450g water again, stir, obtain yellow translucent liquid.
Continue to add emulsifying agent 10g, stir and make it to mix, heat temperature raising to 60 ℃ slowly adds 120g vinyl acetate and 0.8 Potassium Persulphate then, and insulation refluxes.Feed rate is controlled at and added in 6 hours.Be warming up to 90 ℃ then, insulation reaction 1 hour.Be cooled to below 50 ℃, add 3g sodium bicarbonate and 100g dibutyl phthalate, mix, discharging obtains the latex finished product.
