Abstract
The invention discloses a kind of open compressed wood hide glues of overlength, it includes the raw material of following weight parts: the VAE of 20~90 parts by weight, the PVAc white glue with vinyl of 0~60 parts by weight, the acrylate and vinyl acetate emulsion of 10~80 parts by weight, the preservative of the filler of 0~30 parts by weight and the dispersing agent of 0~0.2 parts by weight, the defoaming agent of 0.1~0.2 parts by weight and 0.1~0.2 parts by weight.There is the wood skin glue thermal activation energy under 70~120 DEG C of heat pressing process, still to obtain good expected sticking effect even if glue-line parches completely, that is, have the open performance of overlength.The open compressed wood hide glue water resistance of the overlength is excellent simultaneously, and normal-temperature water is impregnated 7 days and do not come unglued.
Description
Technical field
The invention belongs to bonding technique fields, and in particular to a kind of overlength opens composition and the preparation side of compressed wood hide glue
Method.
Background technique
China is a woodwork big producer, and consumption big country, thereby promotes the flourishing hair of woodworking adhesive stick
Exhibition.With the development of society, people are wooden to wooden consumer article such as furniture woodwork, office woodwork, technique woodwork, gardening
Product, the requirement of life woodwork are higher and higher, are in the past the woodwork of raw material with density board, core-board and common wood etc.
Aesthetics, in terms of have been unable to meet the requirement of people.For this purpose, in density board, core-board and common wood etc.
Substrate surface is bonded the wood skin of the precious natural tree species such as beech, rosewood, red wingceltis, walnut, Manchurian ash, cherry, assigns base
Native texture, the color of material surface rare tree, to achieve the purpose that quality-high and inexpensive.
For the bonding for realizing wood skin and substrate, special wood skin adhesive is needed.Not however as wood skin adhesion technique
Same and its variation, user are also diversified to the performance requirement of wood skin glue.Long to the open hour currently on the market is wood skin gel coating
It is dry slow (generally to be judged with film surface drying time；If the wood skin glue open hour are short, glue-line has been done when pressing wood skin
It is dry, then lose bonding wood skin effect) wood skin glue have biggish demand.Wood skin glue is broadly divided into two classes, first is that ureaformaldehyde
Glue, but limited very big because of free formaldehyde release problem；First is that the white glue with vinyl of environment-friendly type, but its coating drying time it is short (5~
15min surface drying) and cannot completely meet the requirement of user.Especially in summer, demand of the market to long open wood skin glue is strong
It is strong.For this purpose, the wood skin glue for developing the long open hour is very urgent.
Summary of the invention
The present invention is exactly the tight demand for being directed to existing market to long open wood skin glue, provides a kind of compressed wood hide glue
Preparation method can prepare the open wood skin glue of overlength for meeting user's requirement using this method.According to bonding wood skin technique
Difference, wood skin glue can be divided into cold pressing type and hot pressing type wood skin glue.Wood skin glue provided by the invention has thermal activation energy, no matter glue
Whether layer surface drying or parches completely, by the normal heat pressing process of factory, can all obtain good expected sticking effect.Through trying
With inspection, after substrate gluing is placed 72 hours, then 70~120 DEG C of hot pressing fitting wood skins are carried out, adhesive effect is good.And it is cold at present
Pressure or compressed wood hide glue and its use glue thinking, be limited to the surface drying time of glue-line completely, from gluing to press wood skin must be 15
(or even shorter time) completes in minute.Wood skin glue provided by the invention has thermal activation energy, and theory can open hour ratio
Test wants much longer in 72 hours；It compares traditional 15 minutes within 72 hours, is that overlength is open.
The present invention adopts the following technical scheme: a kind of open compressed wood hide glue of overlength, it includes the raw material of following weight parts:
The VAE of 20~90 parts by weight, the PVAc white glue with vinyl of 0~60 parts by weight, the acrylate and vinyl acetate emulsion of 10~80 parts by weight, 0~30 parts by weight
Filler and 0~0.2 parts by weight dispersing agent, the defoaming agent of 0.1~0.2 parts by weight and the anti-corrosion of 0.1~0.2 parts by weight
Agent.
Further, the VAE solid content is 50wt%~57wt%, preferably 54wt%~56wt%.
Further, the PVAc white glue with vinyl, solid content be 25wt%~55wt%, preferably 45wt%~
50wt%.
Further, the acrylate and vinyl acetate emulsion, solid content are 25wt%~55wt%, and wherein acrylate monomer accounts for poly-
Close 10wt%~100wt% of monomer total amount.Preferably, the solid content of acrylate and vinyl acetate emulsion is 45wt%~50wt%, wherein third
Olefin(e) acid ester monomer accounts for 50wt%~80wt% of polymerized monomer total amount.
The present invention also provides the preparation method of the open compressed wood hide glue of overlength, this method are as follows: by VAE, PVAc white glue with vinyl and
Acrylate and vinyl acetate emulsion, filler, dispersing agent, defoaming agent and preservative are uniformly mixed in stirring at normal temperature and get product.
VAE, PVAc white glue with vinyl, acrylate and vinyl acetate emulsion, filler, dispersing agent, defoaming agent, preservative are normal using this field in the present invention
Advise the reagent used.
The filler is filler commonly used in the art, such as can be talcum powder, Paris white and kaolin, fineness
More than 800 mesh.
The dispersing agent is dispersing agent commonly used in the art, such as can be sodium polycarboxylate dipersant.
The preservative is preservative commonly used in the art, such as can be Kathon CG class preservative.
The defoaming agent is defoaming agent commonly used in the art, such as can be mineral oil defoaming agent.
The beneficial effects of the present invention are: (1) the use glue new concept of compressed wood hide glue overlength opening is proposed, mesh is got rid of
It is preceding to be limited to the short constraint of glue-line surface drying fast open hour with glue, when greatly extending the interval from gluing to pressing wood skin
Between, improve the flexibility of pressing wood skin technique；(2) application of the open compressed wood hide glue of overlength, can release gluing and pressing
Necessary closely coupled relationship, allows hot pressing wood skin process independent between wood skin, the progress of hot pressing wood skin concentration (without
Must be as carrying out with being scattered about like the stars with waiting now) energy consumption can be greatly reduced；(3) the wood skin glue has thermal activation, completely can be with
In glue-line surface drying or hot pressing when parching, also solve the problem that normal wood hide glue must wet pressing and caused by seep through strike-through problem, avoid
Seep through strike-through is generated to the adhesion of pressurized equipment and the pollution of product surface resulting from, has not only ensured the quality of product, but also
Simplify the cleaning of equipment；(4) because VAE and acrylate and vinyl acetate emulsion have water resistance, so the open compressed wood hide glue of the overlength is resistance to
Water function admirable, normal-temperature water are impregnated 7 days and are not come unglued, and most wood skin calymmas come unglued for water 1 day in the market.Wood skin glue is good resistance to
Aqueous energy provides guarantee using process for the water paint after bonding wood skin.
