Abstract
The invention discloses a preparation method of a polyvinyl acetate sealant and belongs to the field of chemical engineering. The preparation method comprises that polyvinyl acetate, butanone, terpene resin, talcum powder, carclazyte, tributyl phosphate, magnesium oxide and a benzene dimethylamine tripolymer derivative as raw materials undergo a reaction in a chemical reaction kettle as a reactor at an appropriate temperature for an appropriate time to produce the polyvinyl acetate sealant. The preparation method has the advantages that production processes are simple; and universal equipment is adopted. The polyvinyl acetate sealant is mainly used for sealing of wood gaps, has strong adhesion, good stability, good aging resistance, no pollution and a low price, and is convenient for use.
Description
Technical field
Product of the present invention belongs to chemical field, relates in particular to a kind of preparation method of polyvinyl acetate seal gum.
Background technology
Polyvinyl acetate has another name called polyvinyl acetate (PVA), the polymkeric substance of vinyl-acetic ester, its appearance transparent, 1.19 g/ccs of density, be soluble in methyl alcohol, ketone, ester class, aromatic hydrocarbons, hydrochloric ether, be insoluble to dehydrated alcohol, higher alcohols, alkane, hexanaphthene, water etc., stable in the sun, stable below 125 ℃, darken at 150 ℃, acetic acid is emitted in 225 ℃ of decomposition, generates rosthomite shape insolubles.Mainly use with emulsion form at industrial vinylite, be white milk sap, slightly remaining vinyl-acetic ester smell, its solids content is 30%～60%, range of viscosities is very wide, the pH value is about 5, and main application is: 1. make tackiness agent, the seal gum of the aspects such as timber, paper, fiber, leather, and wherein with the most use, the most general with the timber aspect; 2. owing to its good stability, easily constructing and being destitute of smell, in a large number as the auxiliary material of coating for internal and external wall; 3. as cement additire, can be used for the occasions such as indoor floor, wall, toilet warterproof; 4. be mainly used in stiffening processing, printing and dyeing, flock-adhesion etc. aspect the fabric processing; Its advantage has: bounding force is strong, good stability, resistance to deterioration are good, do not pollute, easy to use, cheap.The polyvinyl acetate second-order transition temperature is lower, only 28 ℃, thereby larger cold flow properties is at room temperature arranged, can not the adhered plastics goods, but it can with multiple material, especially bonding with timber, paper premium properties also can be used as the seal gum of brick and tile, brick masonry surface.Product of the present invention is a kind of polyvinyl acetate seal gum, produce this product with polyvinyl acetate, butanone, terpine resin, talcum powder, carclazyte, tributyl phosphate, magnesium oxide, benzene dimethylamine tripolymer derivative is raw material, take chemical reaction kettle as reaction vessel, and be equipped with suitable temperature and the reaction times prepares seal gum, this preparation method's advantage is: production technique is simple, use general-purpose equipment, the seal gum of producing mainly is used in the sealing in timber slit, and it is strong that this product has a bounding force, good stability, resistance to deterioration is good, pollution-free, easy to use, the advantage such as cheap.
Summary of the invention
The problem to be solved in the present invention provides the method that a kind of batch prepares the polyvinyl acetate seal gum, sealing glue is take polyvinyl acetate as major ingredient, take butanone as thinner, produce seal gum take tackifier, filler, softening agent, promotor, solidifying agent as auxiliary material, sealing glue mainly is used in the sealing in timber slit, the advantage such as have that bounding force is strong, good stability, resistance to deterioration are good, pollution-free, easy to use, cheap.The raw material that production sealing glue uses has: polyvinyl acetate 42%-44%, butanone 31%-33%, terpine resin 6%, talcum powder 5%, carclazyte 6%, tributyl phosphate 3%, magnesium oxide 2%, benzene dimethylamine tripolymer derivative 3%.
The present invention can be achieved through the following technical solutions:
A kind of preparation method of polyvinyl acetate seal gum, its feature is made of following steps:
1. butanone is sent into chemical reaction kettle, start stirrer, rotating speed is 25 rev/mins, adds slowly polyvinyl acetate, while stirring temperature is elevated to about 30 ℃, adds terpine resin, stirring reaction 1 hour.
2. keep temperature-resistant, continue to stir, add slowly talcum powder, stirring reaction added carclazyte after 0.2 hour, continued stirring reaction 0.5 hour.
3. the chemical reaction temperature in the kettle is transferred to normal temperature, continue to stir, add slowly tributyl phosphate, stirring reaction added magnesium oxide after 0.2 hour, the restir reaction adds benzene dimethylamine tripolymer derivative after 0.2 hour, continue to stir to stop after 1 hour stirring, and the blowing packing gets product.
The invention has the beneficial effects as follows: the preparation method that a kind of polyvinyl acetate seal gum is provided, this preparation method's technique is simple, the use general-purpose equipment, the advantages such as the seal gum of producing mainly is used in the sealing in timber slit, and this product has that bounding force is strong, good stability, resistance to deterioration are good, pollution-free, easy to use, cheap.
