Abstract
A white starch emulsoid is prepared from starch, polyvinyl alcohol, polyvinyl acetate, formaldehyde, hydrochloric acid and water. Its advantages include short drying time, no environmental pollution, natural decomposing and high adhesion.
Description
The present invention is the white glue with vinyl in a kind of tackiness agent.
Traditional Virgin's milk is pure chemistry product preparations, though can satisfy the agglutinating needs, its rate of drying is relatively slow, and the raw materials cost height has certain pollution to environment, to human body and certain irritating smell infringement.
Purpose of the present invention will provide a kind of time of drying short exactly, and cost is low, and is free from environmental pollution, human body do not produced the white glue with vinyl of pungent odour.
Content of the present invention is such, by starch 10～27%, and polyvinyl alcohol 20～37%, polyvinyl acetate emulsion content 10～18%, formaldehyde 1～3%, hydrochloric acid 1～3% water 12～58% is formed.Its production method is that polyvinyl alcohol is added water 95～100 ℃ of time dissolvings 3～6 hours of heating, put into a certain amount of hydrochloric acid and formaldehyde, when making dissolving polyvinyl alcohol solution well be cooled to 90 ℃, the starch that will be diluted to pasty state lentamente in advance joins in the polyvinyl alcohol solution, and insulation mixed 30 minutes, put into polyvinyl acetate emulsion when cooling to 60～70 ℃ again, stir and got the W-Gum white glue with vinyl in 2 hours.And described starch can use corn, beans, potato class (as potato, sweet potato etc.) or other crop starch.
Effect of the present invention is such, owing to added W-Gum or other starch, the consumption of chemical feedstocks reduces, and cost is significantly reduced, 1/5th of the former approximately white glue with vinyl of cost, and, owing to directly do not use vinyl acetate between to for plastic, reduced production cost, do not need reactor Dichlorodiphenyl Acetate ethene to carry out polymerization in the production, reduce equipment, thereby reduced the equipment input.On the other hand, traditional about 8 hours of time of drying of white glue with vinyl or longer, and about 7～7.5 hours of the time of drying of white glue with vinyl of the present invention shortened about 30 minutes than traditional white glue with vinyl, and white glue with vinyl of the present invention contains organism, after abandoning as waste, in soil, can be absorbed degraded by microorganism, free from environmental pollution, once synthetic aborning, no waste is got rid of, and also produce irritating smell during use hardly, and its cohesive force to timber, laminate, fiberboard etc. is identical with traditional white glue with vinyl.In addition, white glue with vinyl of the present invention does not freeze in the time of 0～5 ℃.
Embodiment 1, a kind of white starch emulsoid, by W-Gum 22%, polyvinyl alcohol 30%, polyvinyl acetate emulsion content 15%, formaldehyde 2%, hydrochloric acid 2%, water 29% is formed.Its production method is polyvinyl alcohol to be added water heat 98 ℃ and dissolved 5 hours, put into a certain amount of hydrochloric acid and formaldehyde, when making dissolving polyvinyl alcohol solution well be cooled to 90 ℃, the starch that will be diluted to pasty state (being as the criterion to hang hand) lentamente in advance joins in the polyvinyl alcohol solution, and insulation mixed 30 minutes, put into polyvinyl acetate emulsion when cooling to 65 ℃ again, stir and got white starch emulsoid in 2 hours.
Embodiment 2, a kind of white starch emulsoid, by potato starch 18%, polyvinyl alcohol 25%, polyvinyl acetate emulsion content 16%, formaldehyde 1.8%, hydrochloric acid 2%, water 37.2% is formed.Its production method is polyvinyl alcohol to be added water heat 97 ℃ and dissolved 4 hours, put into a certain amount of hydrochloric acid and formaldehyde, when making dissolving polyvinyl alcohol solution well be cooled to 90 ℃, the starch that will be diluted to pasty state (furnishing is hung the paste of hand) lentamente in advance joins in the polyvinyl alcohol solution, and insulation mixed 30 minutes, put into polyvinyl acetate emulsion when cooling to 65 ℃ again, stir and got the W-Gum white glue with vinyl in 2 hours.
Embodiment 3, a kind of white starch emulsoid, by broad bean starch 10%, polyvinyl alcohol 20%, polyvinyl acetate emulsion content 10%, formaldehyde 1%, hydrochloric acid 1%, water 58% is formed.Its production method is polyvinyl alcohol to be added water heat 98 ℃ and dissolved 5 hours, put into a certain amount of hydrochloric acid and formaldehyde, when making dissolving polyvinyl alcohol solution well be cooled to 90 ℃, the starch that will be diluted to pasty state (being as the criterion to hang hand) lentamente in advance joins in the polyvinyl alcohol solution, and insulation mixed 30 minutes, put into polyvinyl acetate emulsion when cooling to 65 ℃ again, stir and got white starch emulsoid in 2 hours.
