Abstract
The invention relates to a process for online reinforcing a corrugated original paper by a corrugated paper plate. The process includes following steps: (1) preparing an intensifier: a. a macromolecule resin of a certain amount being added with proper adjuvant and water and mixed, performing grinding; b. according to a distribution ratio request, adding water of a certain amount and mixed, being performed with treatment at a high voltage viscolizer after being filtered to prepare an intensifier original liquid; c. according to a weight distribution ratio, adding 0.05-0.1 unit stabiliser in 100 units so as to prepare an intensifier emulsion; (2) arranging an intensifier spray coating device on a production line of the corrugated paper plates, adding intensifier emulsion in the spray coating device, to spray coat the corrugated original paper operated on line. The invention has beneficial effects that: because an intensifier capable of rapidly infiltrating and moisture-keeping, self water is equalized thereby realizing objects of increase and keeping, enhancing tenacity and strength of the original paper, and at the same time enhancing self-filming of the intensifier after being dried and solidified, the intensifier is close attached to the original paper, accordingly, anti-drafting or anti-breaking strength of the corrugated original paper is largely increased, and production line speed is also largely improved.
Description
Technical field:
The present invention relates to a kind of production technology of corrugated board, relate in particular to the online technology that fluting medium is strengthened of a kind of corrugated board.
Background technology:
At present; the fluting medium of domestic carton industry generally all adopts the C level fluting medium of being produced as raw material by straw pulp or waste paper; the enterprise that has is in order to save cost; the C level does not reach yet, therefore, and the shortcoming that common corrugated paper ubiquity is of poor quality, intensity is low; disconnected paper phenomenon can often take place on production line; cause shutting down or product rejection, make production efficiency low, the production cost height.And the prior art that strengthens cardboard (case) intensity has plenty of in paperboard surface and sprays the multiple film of gloss oil agent or surface, have plenty of and when papermaking, add reinforcing agent, the water-fast enhancement additive of corrugated board as the development of changzhou Tianyuan chemical company, be multiple macromolecule resin complex aqueous materials, above-mentioned technology all can not strengthen the fluting medium that is moving on the production line, thereby has limitation.
Summary of the invention:
Technical problem to be solved by this invention overcomes the deficiencies in the prior art exactly, provides a kind of and online fluting medium is strengthened and the enhanced process effective, that cost is low.
It is as follows that the present invention solves the problems of the technologies described above the technical scheme of being taked: the online technology that fluting medium is strengthened of corrugated board may further comprise the steps:
(1) preparation reinforcing agent: a, get a certain amount of macromolecule resin and add after an amount of auxiliary agent and water mixes, grind; B, by ratio requirement, add a certain amount of water and mix, filter the back and on high pressure homogenizer, handle, make reinforcing agent stoste; C, by weight ratio, the stabilizing agent that adds 0.05-0.1 part in 100 parts of reinforcing agent stostes is made the reinforcing agent emulsion;
(2) the reinforcing agent spray equipment is set on corrugated paper board production line, and the reinforcing agent emulsion is added spray equipment, the fluting medium of on-line operation is sprayed.
The invention has the beneficial effects as follows: because the reinforcing agent that has adopted a kind of energy rapid permeability and preserved moisture, and onlinely fluting medium is evenly sprayed by spray equipment, the part unsaturated group of reinforcing agent forms as a whole because of reacting with the lignose in the body paper, what have is penetrated into the body paper fibrous inside, can regulate the hygroscopic capacity of body paper, make fluting medium self moisture content reach balanced, the realization humidification is preserved moisture and is toughness reinforcing, strengthen the purpose of body paper, reinforcing agent is done solid back self film forming simultaneously, stick on the body paper tightly, thereby improved the tension or the anti-fracture strength of fluting medium greatly, line speed is increased substantially.
The specific embodiment:
Below in conjunction with specific embodiment the present invention is further described:
