Abstract
The invention discloses starch adhesive and an application of the starch adhesive in bonding of a multi-wall corrugated board. The starch adhesive has high bonding strength and can be used for firmly bonding the multi-wall corrugated board. The starch adhesive is made by adopting a starch-polymer-superfine filler ternary reinforcing and modifying technique, cassava starch is adopted as the starch, an olefin monomer is adopted as the polymer, and superfine fibrous filler is adopted as the superfine filler. The starch-polymer-superfine filler ternary reinforcing and modifying technique comprises the following steps: firstly, dissolving the cassava starch into water, so as to prepare a cassava starch aqueous solution; secondly, adding olefin monomer and superfine fibrous filler into the cassava starch aqueous solution, and preparing cassava starch glue by adopting a grafting-crosslinking glue preparing technique; finally, producing free radicals by the olefin monomer under the initiation action of ultraviolet lights, and grafting the olefin monomer to a cassava starch molecular chain in a certain polymerization degree, so as to form a net-high polymer molecular chain and improve bonding strength and stability.
Description
Technical field
The present invention relates to Modified Starch Adhesive and uses thereof, be specifically related to Starch Adhesive of a kind of high-adhesion energy and uses thereof.
Background technology
Protecting forest resources, under international community's common recognition of preserving the ecological environment, for wooden packing, will become the inexorable trend of domestic and international Development of Packaging Industry; In for wooden packing, due to heavy corrugated cardboard tr, to have intensity high, lightweight, collapsible, saves storage space; Volume and wooden case relatively reduce 20%; Exempt to fumigate convenient outlet, the advantages such as low cost; Therefore use and the development prospect of heavy corrugated cardboard packing are boundless;
The mode of enhancing corrugated cardboard intensity is for increasing a number of plies for corrugated cardboard, and still because the deadweight of corrugated cardboard itself is larger, and its service requirements is relatively high, so the tackiness agent that multi-wall corrugated board is used can not meet the demands; Concrete, the bonding employing amylan between traditional corrugated cardboard body paper, starch belongs to polyose carbohydrate, although can be used as tackiness agent, uses, and its bond strength is not enough, need carry out modification.
Summary of the invention
Technical problem to be solved by this invention is, for above-mentioned deficiency of the prior art, to disclose Starch Adhesive, and for the purposes of bonding multiple corrugated cardboard; The bonding strength of this Modified Starch Adhesive is high, bonding multi-wall corrugated board that can be firm.
The technical solution adopted for the present invention to solve the technical problems is: Starch Adhesive, by starch-polymer-ultra-fine filling material ternary enhancing modified technology, make, described starch is tapioca (flour), and described polymkeric substance is olefinic monomer, and described ultra-fine filling material is ultra-fine fibre shape filler.
Further: above-mentioned ternary enhancing modified technology is:
First, tapioca (flour) is dissolved in to water, makes the tapioca (flour) aqueous solution;
Secondly, in the tapioca (flour) aqueous solution, add olefinic monomer and ultra-fine fibre shape filler, by grafting-crosslinked adhesive-preparing technology, produce Tapioca adhesive;
Finally, under ultraviolet ray causes, make olefinic monomer produce free radical, olefinic monomer is grafted on tapioca (flour) molecular chain with certain polymerization degree, forms netted-high-polymer molecular chain, improves bonding strength and stability.
Further: above-mentioned Modified Starch Adhesive, in per-cent, it comprises following component:
28% tapioca (flour), 55% water, 4% caustic soda soln, 1% borax, 5% tackifier, 5% stablizer, 2% waterproof additive;
Above-mentioned all percentage ratio is weight percentage.
Further: above-mentioned waterproof additive is cross-linked resin.
The invention also discloses the purposes of above-mentioned any Starch Adhesive, specifically be applied to bonding multi-wall corrugated board, when bonding corrugated cardboard, the ultra-fine fibre shape filler in Tapioca adhesive is effectively distributed in the capillary gap of paperboard surface, improves the shock resistance degree of cardboard.
The present invention compared with prior art has the following advantages:
The present invention is by selecting the best tapioca (flour) of cohesiveness to make tackiness agent, and the adhesiveproperties of the tackiness agent finally had to is reached to be provided; Meanwhile, of the present inventionly with tapioca (flour)-alkene body-ultra-fine fibre shape filler binary polymerization fabrication techniques, form, between its molecular chain, assemble the huge hydromeehanics forming centered by polymkeric substance and mention, the viscosity of whole system is increased; Bonding strength and the stability of tackiness agent itself have finally been improved; The present invention, when concrete making, includes sintering solution in its formula, borax, and tackifier, stablizer and waterproof additive, the tackiness agent that makes to make has advantages of waterproof, stable and viscosity is high.
The invention also discloses above-mentioned Modified Starch Adhesive for the purposes of bonding corrugated cardboard, the corrugated cardboard that the present invention is bonding, structure is firm, and the water-repellancy of tack line is high.
