Abstract
The invention discloses an adhesive capable of improving an adhesive force of plywood. The adhesive is prepared from the following raw materials in parts by weight: 95-105 parts of urea resin, 25-30 parts of superfine cellulose powder, 0-0.4 part of phosphoric acid, 0-0.6 part of ammonium chloride, and 0.08-0.12 part of cellulase. The adhesive disclosed by the invention has the advantages that not only can the adhesive force and the viscosity be improved to ensure the product quality, but also the production cost can be greatly reduced.
Description
Technical field
The present invention relates to a kind of tackiness agent for glued board, particularly a kind of tackiness agent improving glued board sticking power.
Background technology
Wood gluing agent is the product for wood processing industry, and the production as glued board, shaving board, laminated product, decorative finishes plate and core-board etc. all needs the tackiness agent of different performance.The appearance of tackiness agent, not only has vital role to saving timber and simplification production technique, makes the matrix material of various performance, thus play the unique function of timber, provide the purposes that some is special.
In traditional glued board industry, mostly several employing UF glue (urea-formaldehyde resin) adds a certain amount of starch (flour) thickening and puts into production.As everyone knows, starch is exactly grain, price, thus production cost also corresponding raising; And this cementing agent must stop squeeze time 30-40min for after product gluing, duration of service is longer, hinders production rate.
Summary of the invention
The object of the invention is to, a kind of tackiness agent improving glued board sticking power is provided.The present invention can not only promote sticking power and viscosity power, thus ensures quality product, and significantly can also reduce production cost.
Technical scheme of the present invention: a kind of tackiness agent improving glued board sticking power, is characterized in that: make by the raw material of following weight parts: urea-formaldehyde resin 95 parts-105 parts, microfine cellulose powder 25-30 part, phosphoric acid 0-0.4 part, ammonium chloride 0-0.6 part, cellulase 0.08-0.12 part.
In the tackiness agent of aforesaid raising glued board sticking power, described urea-formaldehyde resin 100 parts, 28 parts, microfine cellulose powder, phosphoric acid 0.3 part, ammonium chloride 0.2 part, cellulase 0.1 part.
In the tackiness agent of aforesaid raising glued board sticking power, described urea-formaldehyde resin 100 parts, 25 parts, microfine cellulose powder, phosphoric acid 0.1 part, ammonium chloride 0.3 part, cellulase 0.08 part.
In the tackiness agent of aforesaid raising glued board sticking power, described urea-formaldehyde resin 100 parts, 30 parts, microfine cellulose powder, phosphoric acid 0.4 part, ammonium chloride 0.1 part, cellulase 0.12 part.
In the tackiness agent of aforesaid raising glued board sticking power, described microfine cellulose powder is 100 order-150 orders.
In the tackiness agent of aforesaid raising glued board sticking power, described microfine cellulose powder is processed by tangerine bar, straw or wood powder.
Compared with prior art, the present invention is by mixing microfine cellulose powder with urea-formaldehyde resin, phosphoric acid, ammonium chloride, mate cellulase to carry out acting on Mierocrystalline cellulose simultaneously, make the present invention can not only promote sticking power and viscosity power, thus guarantee quality product, and significantly can also reduce production cost.Applicable temperature due to cellulase be 30-70 DEG C, pH between 4.5-7.5, just in time can conform to urea-formaldehyde resin condition, simultaneously because cellulase is fast to the cellulose catalytic reaction times, therefore, can enhance productivity, accelerate the progress of work, shorten the cycle.Mierocrystalline cellulose itself has good water-absorbent, but wetting ability is poor, therefore coordinates the cellulase of upper specified proportion, makes it to have good wetting ability.Mierocrystalline cellulose will lose activity more than 70 DEG C, and glued board after sizing of colding pressing must hot pressing under the high temperature more than 105 DEG C, oven dry, therefore, well can ensure that quality product is unaffected, can also reach and reduce costs, the object of enhancing productivity.The present invention is processed into microfine cellulose powder by tangerine bar, straw or wood powder, reasonable employment waste, reduces production cost, thus economizes on resources, protect environment.
