Description
Technical field
The present invention relates to viscous glutinous agent preparation fields more particularly to a kind of cross-linking method to be modified the side that VAE lotions prepare viscous glutinous agent
Method.
Background technology
VAE lotions are the abbreviations of vinyl acetate-ethylene copolymerization emulsions, be with vinyl acetate and vinyl monomer are substantially former
Macromolecule emulsion made of emulsifier and initiator are copolymerized by high pressure emulsion polymerization is added in material.VAE lotions are mainly used for
Adhesive, coating, cement modifier and paper conversion have many excellent performances.VAE lotions have permanent flexibility, it
The internal plasticization product that can be regarded as polyvinyl acetate emulsion, since it introduces ethylene molecule in polyvinyl acetate molecule
Chain makes acetyl group generate discontinuity, increases the rotary freedom of macromolecular chain, steric restriction is small, and high polymer main chain becomes
Softness, and the migration of plasticizer will not occur, it ensure that product is permanently soft.VAE lotions have preferable resistance to acid and alkali,
VAE lotions can keep stability under weak acid and weak base existence condition, no matter therefore it mixed all with weak acid or weak base
Demulsifying phenomenon will not occur, products application range is wider.VAE lotions can ultraviolet-resistant aging, due to VAE lotions be use second
Reactive plasticizer of the alkene as copolymer makes VAE polymer that there is internal plasticization, plasticizer will not migrate, so as to avoid
Polymer performance aging.Therefore, be not only VAE lotions has good stability to ultraviolet light, is exactly same after VAE emulsion film formings
Also this feature can be kept.VAE lotions have good film forming, and lotion adhesive can only form transparent in a certain temperature
Film, this temperature is minimum film formation temperature.VAE minimum film formation temperature is generally below 5 DEG C, therefore can form a film very well, epithelium
There is preferable barrier property to water droplet.VAE lotions have good cementability, it is to fiber, timber, paper, plastic film, aluminium
The products such as foil, cement, ceramics have good adhesive effect.But itself there is also defects, such as its water resistance, solvent resistant
Property and acid resistance are undesirable.
Due to the linear structure of the molecule of VAE lotions, therefore the water resistance of corresponding adhesive is poor.It is usually necessary to use crosslinkings
Method is modified it processing, when by linear structure to be changed into the degree of cross linking between macromolecular in film forming procedure suitable for modified system
3 D cross-linked reticular structure when, water resistance and other many performances could be improved significantly.
The present invention is directed to existing VAE lotions existing defect in terms of adhesive, by handing over itself and other auxiliary agents
Connection is modified so that the polymer after crosslinking has higher water resistance, flexibility and viscous stickiness, can be widely applied to building row
Industry, apparel industry and other industrial circles.
Invention content
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of modification VAE lotions preparation of cross-linking method is viscous

Step 2: stopping heating, it is cooled to room temperature, it is poly- that TDI toluene solutions, liquid glyoxal and liquid is added into beaker
Sodium acrylate after stirring evenly, adds butyl maleate dibutyl tin, after 10-15 minutes ultrasonic, at the beginning of modified emulsion is made
Liquid；
Step 3: liquid at the beginning of modified emulsion obtained in step 2 is mixed with portland cement, silica sand and deionized water
After even, the viscous glutinous agent of target is made；
Wherein, VAE lotions, sodium hydroxide solution, TDI toluene solutions, liquid glyoxal, liquid polypropylene acid sodium, Malaysia
Sour mono-n-butylester dibutyl tin, portland cement, silica sand and deionized water dosage be：
Further, the mass fraction of solute is 28-35% in TDI toluene solutions.
Further, the antifreezing agent of 10-15ml is additionally added in step 3, antifreezing agent is ethylene glycol.
Further, in step 1, the temperature of heating water bath is controlled at 60-65 DEG C.
The invention discloses a kind of cross-linking methods to be modified the method that VAE lotions prepare viscous glutinous agent, by by VAE lotions with it is other
Auxiliary agent carries out cross-linking modified so that the polymer after crosslinking has higher water resistance, flexibility and viscous stickiness, can extensive use
In building trade, apparel industry and other industrial circles.
