Abstract
A modified vinyl polyacetate emulsion as the adhesive of woo is prepared from vinyl acetate, unsaturated carboxylic acid and/or its hydroxyalkyl ester, unsaturated alkyl carboxylate with tert-amino group, polyvinyl alcohol and water through polymerizing under existance of small quantity trigger. Its advantages are high resistance to solvnet, high shear and tension strength and high adhering speed.
Description
The present invention relates to a kind of polyvinyl acetate emulsion of modification, especially a kind of tackiness agent that glueds joint usefulness as timber.
The manufacturing of current timber splicing and laminated plank, the general traditional product of using: polyvinyl acetate emulsion or urea-formaldehyde resin, it is poor that the former glueds joint power, and not anti-solvent, not water-fast yet, the latter is the good tackiness agent of laminated plank, but it contains residual formaldehyde---a kind of carcinogenic substance, thereby human body and environment caused serious harm and pollution.
The objective of the invention is weak point, develop a kind of non-harmful good quality wood tackiness agent at the above polyvinyl acetate emulsion and urea-formaldehyde resin adhesive.
The realization of the object of the invention is in traditional polyvinyl acetate emulsion, introduces the unsaturated carboxylic acid monomer or and the tertiary amine groups monomer of band interlinkage group.
The composition and the weight percent thereof of the chain modified polyvinyl acetate emulsion of preparation selfing are:
Vinyl acetate 42-50%;
Unsaturated carboxylic acid and/or its hydroxy alkyl ester 0.5-10%;
The unsaturated carboxylic acid alkyl ester 0.05-10% of band tertiary amine groups;
Polyvinyl alcohol 0.05-10%;
Water surplus, polymerization in the presence of a small amount of initiator and making.
The molecular formula of unsaturated carboxylic acid of the present invention or its hydroxy alkyl ester is:
R in the following formula
1Be H or CH
3, R
2Be H or C
1-C
3Hydroxyalkyl, OR
2Also can be the N-methylol, as vinylformic acid, methacrylic acid, vinylformic acid or (methyl) acrylic acid hydroxy alkyl (C
1-C
3) ester and acrylic or methacrylic acid N-methylol ester, (methyl) glycidyl acrylate etc.; The esters of unsaturated carboxylic acids of described band tertiary amine groups such as diethylamine acrylic or methacrylic acetoacetic ester or its homologue; Described polyvinyl alcohol comprises the polyvinyl alcohol of the polymerization-grade of different polymerization degree and viscosity.
Because the present invention is in traditional polyvinyl acetate emulsion, introduce the unsaturated carboxylic acid monomer and the tertiary amine groups monomer of band interlinkage group, the unsaturated carboxylic acid monomer of band interlinkage group can carry out at a lower temperature from interlinkage or make hydroxyalkyl and carboxyl between interlinkage, thereby improve bonding force, Joint strength and the solvent resistance of film forming matter; The tertiary amine groups monomer then can improve the sticking power of emulsion to timber, thereby improves the workability of tackiness agent and improve its stripping strength.By adjusting the unsaturated carboxylic acid monomer and the monomeric ratio of tertiary amine groups of band interlinkage group, can produce the series product of different purposes.Use this product as tackiness agent, can at room temperature solidify, also can shorten its set time by the method for heating.Can be used for joggle, finger, the splicing of timber and timber, and the splicing that is used for laminated plank, make engaged timber that high Joint strength and stripping strength be arranged.Because this product does not contain formaldehyde, belong to environmentfriendly products, can replace traditional urea-formaldehyde resin product.
Embodiment: the preparation of the chain modified polyvinyl acetate emulsion of selfing, can by 47 parts of vinyl acetates, 2.5 parts of polyvinyl alcohol, 1 part of vinylformic acid, 1.5 parts of vinylformic acid N-methylol esters and 48 parts of water in the presence of 0.05 part of initiator, get in 68-75 ℃ of polymerization.The product that is made by present embodiment is the oyster white viscous fluid, and viscosity is 8000mp.s (25 ℃), can be used for glueing joint timber, and promptly curable through 75--80 ℃ and 2 minutes, its stripping strength is high.
