Abstract
The invention discloses a formaldehyde-free super glue film and a manufacturing method thereof. In the manufacturing method, polypropylene resin, a main antioxidant, an auxiliary antioxidant and a filler are taken as raw materials; and a thin film is manufactured and is formed into the formaldehyde-free super glue film by adopting biaxially-oriented polypropylene (BOPP), so the longitudinal tensile strength and transverse tensile strength of the thin film are greatly strengthened. As the main and auxiliary antioxidants are added into the formula, the resin can be prevented from influencing the strength and service life of the thin film after being machined and plastified at high temperature. As graphite is added into the formula, the formaldehyde-free super glue film has a relatively higher heat-conducting property and relatively higher ageing resistance.
Description
Technical field
The present invention relates to a kind of glued membrane and manufacture method thereof, more specifically, the present invention relates to powerful glued membrane of a kind of zero formaldehyde and manufacture method thereof.
Background technology
Since oneth century, most glued board, multi-layer solid wood composite base material, employed tackiness agent is to contain formaldehyde, contain virose synthesizing liquid glue in (for example urea formaldehyde glue, melamino-formaldehyde glue etc.) in manufacturing processed.These synthetic adhesives are except the formaldehyde that contains harmful to human, because it is a liquid state, in use, generally with the drum-type spreadometer, with adhesive applicating on veneer (ply), after causing dried veneer to absorb tackiness agent like this, phenomenon is upheld in the expansion that veneer takes place.Therefore, cause the defective that " hollow " and " sandwich " arranged between veneer and the veneer through regular meeting.In addition, after veneer has absorbed liquid glue, can improve veneer water ratio and moisture content of plywood, have a strong impact on the glued board size stability, even phenomenon such as be distorted; Used in addition tackiness agent water resistance is poor.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides the manufacture method of the powerful glued membrane of a kind of zero formaldehyde, it comprises the steps:
1) selects raw material: acrylic resin 100 weight parts, primary antioxidant 0.1-1 weight part, auxiliary antioxidant 0.1-1 weight part, weighting agent 1-20 weight part;
2), go up extrusion moulding or calendering formation forms film at plastic molding machinery equipment (as casting machine, twin screw extruder etc.) with above-mentioned each raw material uniform mixing in proportion;
3) film is carried out two-way stretch, obtain the powerful glued membrane of zero formaldehyde.
As a preferred method of the present invention, wherein each components contents is:
Acrylic resin 100 weight parts, primary antioxidant 0.1-0.5 weight part, auxiliary antioxidant 0.5-1 weight part, weighting agent 1-5 weight part;
As another preferable methods of the present invention, the used acrylic resin of the present invention is a kind of crystalline polymer of compound with regular structure, is the thermoplastic resin of light oyster white pellet, tasteless, nontoxic, light weight; Can pass through substance law or solvent method, be monomer with the propylene, forms through catalyzed polymerization, refining, granulation.The preferred number average molecular weight scope is 200,000 to 600,000 acrylic resin.
As another preferable methods of the present invention, the used primary antioxidant of the present invention can be oxidation inhibitor JY-1076 or oxidation inhibitor JY-1010; Oxidation inhibitor JY-1010 is a kind of polynary hindered phenol antioxygen, and outward appearance is white or little yellow crystal powder; Be dissolved in organic solvents such as benzene, acetone, chloroform, be slightly soluble in ethanol, water insoluble.Heat-resisting water and washing composition extracting are good, and volatility is low, and be good with the most polymers consistency; Have excellent thermostability and hot-air aging resistance.Nondiscoloration, do not pollute, do not have and smell tasteless, non-toxic efficient.With auxiliary antioxidant JY-168 or DLTDP and be used for polymkeric substance, can significantly improve its heat-resistant stability and processing stability, be one of at present outstanding oxidation inhibitor kind.
Generally the primary antioxidant add-on is advisable with about 0.3% in the polyolefine, is no more than 1% at most, if but add-on is lower than 0.1%, and antioxidant property will sharply descend.When primary antioxidant JY-1010, JY-1076 few additive, should add the auxiliary antioxidant of isodose or double quantity, as phosphorous acid ester or monothioester class all can because major-minor oxidation inhibitor synergy, can significantly improve the anti-oxidant life-span of goods.In the present invention with respect to 100 weight part acrylic resins, the preferred 0.1-1 weight part of the addition of primary antioxidant, more preferably 0.1-0.5 weight part.
As another preferable methods of the present invention, the used auxiliary antioxidant of the present invention can be oxidation inhibitor JY-168, anti-oxidant DLTP, oxidation inhibitor DLTDP, oxidation inhibitor DSTP, phosphite ester kind antioxidant or monothioester kind antioxidant; Anti-oxidant DLTP wherein, chemical name is a Tyox B, 40～66 ℃ of fusing points, consistency is good, and plastification is arranged, white powder.
Generally the auxiliary antioxidant add-on is advisable with 0.1-1% in the polyolefine, and with respect to 100 weight part acrylic resins, the auxiliary antioxidant consumption is the 0.1-1 weight part among the present invention, preferred 0.5-1 weight part.
As another preferable methods of the present invention, the used weighting agent of the present invention is polyolefin resin filler commonly used, can be graphite, kaolin, diatomite, talcum powder, carbon black etc., is used to improve the heat conductivility and the ageing-resistant performance of film.With respect to 100 weight part acrylic resins, the consumption of weighting agent is the 1-20 weight part, preferred 1-5 weight part.
The present invention also provides the zero formaldehyde that is formed by above-mentioned each method manufacturing powerful glued membrane.
The present invention also provides the above-mentioned zero formaldehyde purposes that powerful glued membrane is used to produce glued board.
This purposes realizes as follows:
1, wood single-plate is intersected in length and breadth assembly and arrange, the powerful glued membrane of above-mentioned zero formaldehyde of lay becomes the plate group between veneer and veneer;
2, plate group that assembly is good is sent in the thermocompressor, and under the heating and pressurizing condition (temperature 180-230 ℃, pressure 8-15KG/CM
2Under the condition), with the powerful glued membrane fusing of above-mentioned zero formaldehyde;
3, the plate group after the hot pressing is sent in the chilling press, allowed the adhesive film that has melted in the plate group, under high pressure closely glue together with veneer, cooling promptly gets the glued board with good bonding strength.
Beneficial effect of the present invention is embodied in the following aspects: 1, main raw material is a polypropylene, its formaldehydeless, nontoxic, odorless, and mechanical strength, rigidity more are better than polyethylene.2, adopt two-way stretch (BOPP) and the method for moulding behind the manufacturing film, improve the vertical and horizontal tensile strength of film greatly.Therefore, the glued board that uses this glued membrane to make, itself and wood single-plate adherent bonding strength are even more ideal.3, in prescription, be furnished with oxidation inhibitor, auxiliary antioxidant, prevent that resin from after the plasticizing of processing high temperature, influencing the intensity and the work-ing life of film.4, be added with graphite in the prescription, have heat conductivility and ageing-resistant performance preferably.5, the powerful glued membrane of zero formaldehyde of the present invention has good water resistance.
