Abstract
The invention discloses a nano mildew-proof quick-drying white latex and preparing method thereof. The nano mildew-proof quick-drying white latex is constituted of polyvinyl alcohol, kaolin, light calcium carbonate, formaldehyde, sodium hydroxide, hydrochloric acid and inorganic nano mildew-proof material, and uses inorganic material of high proportioning and novel high technological inorganic sterilization mildew-proof material to increase adhesion strength, quick-drying property and mildew-proof capability of the white latex. By using property of separating out water at high temperature for polyvinyl alcohol formaldehyde solution, kaolin and light calcium carbonate can be directly added, and technique is simplified. The invention can be widely used for decoration project and firework pot adhesion.
Description
Technical field
The present invention relates to a kind of nano mildew-proof quick-drying white emulsion and preparation method thereof
Background technology
White glue with vinyl is the water accack that a class consumption is very big, be of wide application, and mainly makes caking agent in wood furniture making, family, shop or occasions such as office building finishing, paper product processing and uses.CN1186089A has disclosed a kind of water-resistant anti-freezing latex, do not use the traditional raw material vinyl acetate between to for plastic, but make binding agent with polyvinyl formal, urea-formaldehyde resin, methylcellulose gum, treated starch, mixing a small amount of wilkinite or light calcium carbonate makes, reduced production cost of products, and made product have certain water resistance and frost resistance.But traditional water accack often uses the organic synthesis mould inhibitor prevents that it from taking place in storing and using go mouldy.There is poor heat resistance in the organic synthesis mould inhibitor, easily decomposes and produce shortcomings such as objectionable impurities, security be relatively poor, with strong points.Simultaneously, the people is contacted inevitably with wherein organic mould inhibitor because tackiness agent in use contacts with the people through regular meeting.Because traditional organic mould inhibitor all has certain toxicity, long-term contact meeting accumulates in human body, will the user is healthy works the mischief to contact.
Summary of the invention
It is faster to the objective of the invention is to develop a kind of rate of drying, and bonding strength is higher, and the better white glue with vinyl of anti-mold effect just provides a kind of nano mildew-proof quick-drying white emulsion and preparation method thereof.
Each component of nano mildew-proof quick-drying white emulsion of the present invention and weight percent thereof consist of:
Polyvinyl alcohol 8.5～11.5%
Hydrochloric acid 0.9～1.3%
Formaldehyde 1.7～2.3%
Sodium hydroxide 0.32～0.46%
Urea 0.4～0.6%
Kaolin 6.8～10.0%
Light calcium carbonate 5.0～8.0%
W-Gum 1.5～4.0%
Softening agent 0.5～0.9%
Inorganic nano mould inhibitor 0.13～0.26%
Tap water 65～70%
Preparation method of the present invention is:
In reactor, add entry by proportioning earlier, start stirring, with the polyvinyl alcohol input, be warming up to 90～95 ℃, dissolved 1～2 hour, add hydrochloric acid, formaldehyde, temperature of reaction is 90～95 ℃, when material obviously turns white and occurs being separated, adds sodium hydroxide solution, in and material in acid to pH value be 6.0～7.0, be cooled to 80～85 ℃ simultaneously, add urea soln, 80～85 ℃ of isothermal reactions 30～45 minutes; Then when temperature of charge is 80～85 ℃, directly add feed kaolin, light calcium carbonate, the fully wetting and dispersion of water that allows inorganic raw material be separated to separate out was stirred 30～45 minutes; The suspension that adds W-Gum then 80 ℃～85 ℃ following gelatinizations 30～45 minutes, is cooled to 40～45 ℃, adds softening agent, nanometer mildew proofing agent, continues to stir 1～2 hour, through the strainer filtering discharging, obtains product of the present invention.
Positively effect of the present invention is: use polyvinyl formal as the organic bonding material, in aldolization, reduce the formaldehyde usage quantity, be that the formaldehyde consumption only is 20～30% of polyvinyl alcohol quality, aldehyde reaction can proceed to equally and be separated, residual formaldehyde has reduced, after the urea-formaldehyde resin that generates with urea reaction seldom.Do soon for making tackiness agent provided by the invention, bonding strength is good, more kaolin and light calcium carbonate have been used, the mass ratio of polyvinyl alcohol and kaolin, light calcium carbonate mixture is controlled at 1: 1.2～1.8, kaolin is used as a kind of mineral binder bond, light calcium carbonate has then been brought into play the effect of pigment, filler and fluidity improver, because the inorganics consumption is big, so added an amount of softening agent in the product.Nano-TiO
2The introducing of particle and nano Ag particles makes tackiness agent break away from traditional employing organic compound carries out mildew-resistant as mould inhibitor the practice.
Use novel nano inorganic sterilant to come mildew-resistant, because it constitutes nano-TiO
2Particle and nano Ag particles are compared with traditional organic compound mould inhibitor, and its advantage is: 1. anti-mold effect is good, almost can both play all bacteriums and hinder and the elimination effect.2. the continuous action time long because TiO
2Particle and nano Ag particles have good chemical stability, so it can dauer effect.3. chemical property is stable, have no adverse effects with skin contact, and be safety non-toxic to human body, there is not potential hazard.
