Description

Modified adhesive that a kind of two-shipper combines and preparation method thereof
Technical field
The invention belongs to man-made board technology field, particularly relate to modified adhesive of a kind of two-shipper combination and preparation method thereof.
Background technology
Along with the Economic development of the mankind and the new line of environmental consciousness, all over the world, especially developed country, developing country are for the regulation of the burst size of methanal of various wood-based plate (comprising glued board, shaving board, fiberboard and core-board) and requirement, more and more stricter, therefore, relevant expert, scholar also research and develop manufacture method and the relative adhesive of various low formaldehyde or zero formaldehyde wood-based plate by every means.
At present, the main adhesive manufacturing wood-based plate is urea formaldehyde resins, melamine resin and resol.These synthetic resins all contain the formaldehyde of toxic human body, therefore gradually by consumer groups and environmental protection unit repel.In order to obtain the wood-based plate of formaldehydeless murder by poisoning, also have developed some formaldehyde-free rubber sticks in recent years, being applied in the manufacture of wood-based plate.
Summary of the invention
At present, the existing tackiness agent be applied on wood-based plate can be sorted out as follows:
The first kind: natural gum series.Such as, starch based, albumin glue, bean gum etc., these tackiness agent are not containing formaldehyde, and price is also suitable, but bonding strength poor be main drawback.
Equations of The Second Kind: MDI series.These resins comprise epoxy resin and urethane resin, in use using isocyanic ester as solidifying agent, there is splendid bonding strength, unfortunately expensive and the polymerization methods of two component must be taked to use, operational difficulty, is therefore still difficult to be used in the manufacture of wood-based plate.
3rd class: thermally melting glued membrane series.Adopt thermoplastics (such as, polyethylene, polypropylene) to be processed into the glued membrane of film like through blowing, replace traditional liquid state Resin adhesive.Use this glued membrane, formaldehydeless, also can obtain good bonding strength, price is also suitable, just in the manufacturing process of glued board, the first hot pressing of palpus, then just colds pressing, this first cold pressing with tradition after the manufacturing process of hot pressing contrary, directly cannot be applied on existing processing mechanical apparatus, must mechanical means be transformed, greatly will increase investment cost, this, for the producer of existing use traditional type technique, is short of enough magnetisms.
In addition, above-mentioned three class aldehyde-free cements all have a common ground, are exactly all using organic materials and macromolecule resin as main raw material, and only when needs modification or reinforcement, just add a small amount of inorganic filler (such as: calcium carbonate, kaolin).
For solving the above-mentioned problems in the prior art, the invention provides one both formaldehydeless, bonding strength good, price is low, existing machinery apparatus processing wood-based plate can be directly applied to again, without the need to adding or transforming old mechanical means, also need not change the operator scheme of long-term habits, be easy to the modified adhesive that combines by wood-based plate producer of the two-shipper received and preparation method thereof.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
The modified adhesive that a kind of two-shipper combines, by inorganic ternary system material and organic macromolecule resin, and properties-correcting agent mixing preparation forms, wherein the weight percent of properties-correcting agent is 0 ~ 3%, all the other weight percents are inorganic ternary system material and organic macromolecule resin, and the weight allotment ratio between inorganic ternary system material and organic macromolecule resin is (5 ~ 95): (95 ~ 5).
Further, described inorganic ternary system material is the triple combination of magnesium oxide, magnesium chloride and water.
Further, described magnesium oxide, between magnesium chloride and water weight allotment ratio be 2:1:1.
Further, described organic polymer resin is polyvinyl acetate resins or polyvinyl alcohol.
Further, described properties-correcting agent comprises catalyzer, retardant, water-resisting agent, and the weight percent of catalyzer, retardant, water-resisting agent is 0 ~ 1%.
A preparation method for the modified adhesive that described two-shipper combines, comprises the following steps: first by water-soluble for magnesium chloride formation bittern, and stir; Then magnesium oxide is added in bittern, and stir, form the inorganic mixed solution of ternary system; Finally polyvinyl acetate resins or polyvinyl alcohol are added the inorganic mixed solution of ternary system, stir, make the modified adhesive that two-shipper combines.
Further, after " magnesium oxide is added in bittern, and stirs ", first properties-correcting agent joined in the inorganic mixed solution of ternary system, stir, then add described polyvinyl acetate resins or polyvinyl alcohol.
The invention has the beneficial effects as follows:
The present invention passes through technique scheme, the modified adhesive that the two-shipper prepared combines neither contains formaldehyde, has good bonding strength, price is extremely low simultaneously, existing machinery apparatus processing wood-based plate can be directly applied to again, without the need to adding or transforming old mechanical means, also need not change the operator scheme of long-term habits, to be easy to receive by wood-based plate producer, the market competitiveness is strong, is easy to sales promotion; But also inorganic ternary system material and the proportioning organically between macromolecule resin can be adjusted according to product demand, to cold pressing the product of effect and different bonding strength to prepare difference, meet the needs of different users, to be applicable to produce different wood-based plate.
