Abstract
The invention belongs to the field of wood processing industries, and particularly relates to an adhesive for manufacturing a flexible decoration veneer. The adhesive for manufacturing the flexible decoration veneer is formed by uniformly mixing urea glue, white glue, flour, lignin and cationic surface active agents, and the weight ratio of urea glue to white glue to flour to lignin to cationic surface active agents is 100:(40-60):(5-15):(5-15):(0.1-0.5). The adhesive disclosed by the invention has the characteristics of fast surface dry, high adhesive strength and difficulty in adhesive permeation, solves the problem that glued non-woven fabrics are easily adhered mutually during drum winding in a manufacturing process of the flexible decoration veneer, and also solves the problem of adhesive permeation so as to ensure the beauty of the flexible decoration veneer.
Description
Technical field
The invention belongs to wood working industry, particularly relate to a kind of tackiness agent for the manufacture of flexible decoration veneer.
Background technology
General natural veneer or recombinant decorative veneer, especially micro veneer are all more crisp, flexible not enough, easy to crack, are not suitable for the decoration in special type structure face.Flexible decoration veneer be natural veneer or recombinant decorative veneer back side compound paste the strongthener such as non-woven fabrics or kraft paper can coiling, the good decorative veneer of snappiness.So both enhance the snappiness of recombinant decorative veneer, turn increase the integral thickness of product, save timber resources.This veneer can be used for all kinds of special-shaped curved decorative faced, is also applicable to the facing in basse-taille face, has widened the range of application of traditional veneer.
The thermocompressor that prior art wood working industry is conventional is multiple deck press, and non-woven fabrics is the drum of cloth, therefore need nonwoven fabric roll tubular to launch, and cut into sheet according to the length of veneer, then plywood production technology conveniently carries out applying glue, stickup, cold-hot pressure.Due to non-woven fabrics carry out roller applying glue time, can involve in cloth glue machine, cannot normally applying glue, therefore, someone adopts glue spraying mode to carry out applying glue, as scientific and technical literature: " research of Process of Making Soft Artificial Decorative Veneer ", Li Niancun, Xiang Qin, Yang Canming, Zhongnan Forestry Inst.'s journal, in June, 2000, the 20th volume the 2nd phase.
Above-mentioned document adopts solid content to be 55%(massfraction) modified urea-formaldehyde resin glue be tackiness agent, and adopt the mode of glue spraying to carry out applying glue, there is tackiness agent cost high, need the technique changing conventional roller coat applying glue, the defects such as operational requirement is high, easy strike-through.
For this reason, under the prerequisite not changing resin application methods, adopt and the mode of non-woven fabrics continuous sizing is carried out applying glue, namely first non-woven fabrics is launched, by the outlet reel again at cloth glue machine after roller applying glue, thus non-woven fabrics is strained exceptionally straight, avoid involving in cloth glue machine.
Above-mentioned technique involves in the problem of cloth glue machine when solving non-woven fabrics applying glue, but during non-woven fabrics reel after applying glue, tackiness agent can solidify, and makes non-woven fabrics mutually bonding, can not again launch to cut into sheet, can not enter next process.Therefore, in the urgent need to a kind of energy surface drying rapidly, but the tackiness agent of final bonding strength is not affected.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide a kind of tackiness agent for the manufacture of flexible decoration veneer, this tackiness agent has rapid surface drying, bonding strength feature that is high, not easily strike-through.
In order to realize above-mentioned object, present invention employs following technical scheme:
A kind of tackiness agent for the manufacture of flexible decoration veneer, this tackiness agent by urinating glue, white glue, flour, xylogen, cats product Homogeneous phase mixing form, its quality proportioning is: urine glue: white glue: flour: xylogen: cats product=100:(40 ~ 60): (5 ~ 15): (5 ~ 15): (0.1 ~ 0.5).
As preferably, described urine glue: white glue: flour: xylogen: cats product=100:(40 ~ 50): (5 ~ 10): (5 ~ 10): (0.1 ~ 0.2).
As preferably, described urine glue: white glue: flour: xylogen: cats product=100:40:5:5:0.1.
As preferably, described urine glue: white glue: flour: xylogen: cats product=100:(50 ~ 60): (10 ~ 15): (10 ~ 15): (0.2 ~ 0.5).
As preferably, described urine glue: white glue: flour: xylogen: cats product=100:60:15:15:0.5.
As preferably, described described cats product is Dodecyl trimethyl ammonium chloride or cetalkonium chloride.
The present invention, owing to have employed above-mentioned technical scheme, adopts xylogen to replace part flour, can not only reduce the usage quantity of flour, reduce production cost, and can absorb the part free formaldehyde in tackiness agent, reduce the burst size of methanal of flexible decoration veneer further.The features such as it is good that cats product has chemical stability, heat-resisting, fast light, withstand voltage, strong alkali-acid resistance, also have the performances such as excellent perviousness, emulsifying property, flexibility, static resistance and sterilization.The interpolation of cats product, the glue-line of flexible decoration veneer can not only be made to have certain snappiness, reduce the fragility of glue-line, avoid flexible decoration veneer breakage in use, and flexible decoration veneer can also be made to have mildew-resistant, rot-resistant function, extend the work-ing life of product.Adopt above-mentioned adhesive ratio, and resin added controls at 30 ~ 50g/m
2, on non-woven fabrics, easy surface drying rapidly after applying glue, can execute the non-woven fabrics reel after glue and not be glued together, conveniently enter next step operation; Meanwhile, after hot-forming, glue neither infiltrates into recombinant decorative veneer upper surface, also impermeable to non-woven fabrics lower surface, does not affect product appearance quality.The present invention adopts rational adhesive ratio and resin added, easily bonding mutually when solving the non-woven fabrics reel after applying glue, and the strike-through problem of hot-forming rear product surface.
In sum, the present invention has following beneficial effect:
1, the present invention has rapid surface drying, bonding strength feature that is high, not easily strike-through;
2, the invention solves in flexible decoration veneer manufacturing processed, problem easily bonding mutually during non-woven fabrics reel after applying glue;
3, this invention also solves strike-through problem, ensure the attractive in appearance of flexible decoration veneer.
Embodiment
This specific embodiment is only explanation of the invention; it is not limitation of the present invention; those skilled in the art can make to the present embodiment the amendment not having creative contribution as required after reading this specification sheets, as long as but be all subject to the protection of patent law in right of the present invention.
embodiment 1
A kind of tackiness agent for the manufacture of flexible decoration veneer, this tackiness agent by urinating glue, white glue, flour, xylogen, cats product Homogeneous phase mixing form, bonding strength is affected because tackiness agent is subject to variation of ambient temperature, therefore, in actual use, adhesive ratio should be regulated with seasonal variation.As: in summer, temperature is higher, and adhesive solidification is very fast, and employing quality proportioning is: urine glue: white glue: flour: xylogen: cats product=100:40:5:5:0.1; And winter temperature is lower, adhesive solidification is comparatively slow, then employing quality proportioning is: urine glue: white glue: flour: xylogen: cats product=100:60:15:15:0.5.Described cats product is Dodecyl trimethyl ammonium chloride or cetalkonium chloride.
