Abstract
The present invention relates to a high-speed heat coating technology for water basal flame retardant coating paper. The high-speed heat coating technology is characterized in that water basal flame retardant is heated to cause paper moving at a high speed on a coating machine to be immersed in the water basal flame retardant by passing through the water basal flame retardant. The heating temperature of the water basal flame retardant is higher than room temperature and lower than 100 DEG C. The high-speed heat coating technology of the present invention accelerates the immersion of paper in the water basal flame retardant by heating the water basal flame retardant to cause the paper to be immersed by the water basal flame retardant in a short time, increases the variety universality of paper treated by the flame retardant, and solves the problem which is not solved by the traditional normal temperature immersion that high water resistant paper can not be industrially coated at a high speed.
Description
Technical field
The invention belongs to the coating production technology of paper product dip-coating water-based flame-stabilizing on coating machine.
Background technology
Fire-retardant engineering mainly is divided into two kinds with the production technology of paper product (being commonly called as fireproofed paper):
First kind adds fire proofing when being papermaking in paper pulp.This kind production technology paper making additive and fire proofing aborning is difficult to select, responsiveness, and the blowdown environmental issue is difficult to solve.And the kind of producing paper is subjected to the limitation of papermaking equipment, do not have broad spectrum activity, the production cost height.Second kind of production technology is paper product post processing production technology.Dual mode is generally also arranged, the one, agent makes paper product have flame retardant effect to finished paper through spray coated flame retardant.Low lighter suitable this kind mode of paper product of paper product, grammes per square metre of paper product, gel content that general density is less.The 2nd, finished paper makes paper product have flame retardant effect through the dip-coating fire retardant.Must pass through dip-coating for density paper product big, that gel content is high, grammes per square metre is heavier.
For dipping process, fire retardant must soak into paper product makes it to be saturation state, just can reach more satisfactory result of use.But general paper product such as high-strength corrugation, wood pulp ox-hide, white board are difficult to soak at short notice, and the difficult fire retardant that makes soaks into paper product under normal temperature on the dip-coating coating machine of suitability for industrialized production.Coating machine that coating speed is 60m/min for example, its immersion trough length is 4 meters, the soak time of the paper product of this coating in fire retardant is 4 seconds, and in the time of this weak point being can not be saturable, even attach the WATER REPELLENCY that strong bleeding agent also can't fundamentally solve paper product.
Soak test to following paper product:
The water-based flame-stabilizing prescription is, by weight percentage: ammonium phosphate or ammonium sulfate 10%, boric acid 2%, borax 2%, water 86%.
The U.S. produces long fiber wood pulp brown paper 150g/m
2, penetration period is 360min; Homemade high-strength corrugation 150g/m
2, penetration period is 30min; Homemade white board 350g/m
2, penetration period is 600min.Result of the test shows that above-mentioned paper product can't carry out under the normal temperature situation on coating machine at a high speed.
Summary of the invention
Technical problem to be solved by this invention provides and a kind ofly makes water base sex flame retardant soak into paper product at short notice rapidly, the technology of dip-coating paper product on coating machine.
The hot coating process of high speed of a kind of water-based flame-stabilizing dip-coating paper product of the present invention, it is characterized in that water-based flame-stabilizing heated is immersed in high-speed motion on coating machine paper product to pass through water-based flame-stabilizing in the water-based flame-stabilizing.
The heating-up temperature of water-based flame-stabilizing is: be higher than room temperature and be lower than 100 ℃, be lower than under 100 ℃, general temperature is high more good more.
The present invention has quickened the immersion of water-based flame-stabilizing to paper product by the water-based flame-stabilizing of heating, and makes at short notice water-based flame-stabilizing is soaked into paper product, is beneficial to realize industrialized production.The working method of coating machine and structure need not change, and water-based flame-stabilizing can be the fire retardant of existing various compositions, heating element heater just is set on the container with the splendid attire fire retardant heats fire retardant and get final product.Heating element heater can be modes such as electrical heating elements, steam heat-exchanging, conduction oil heat exchange, can regulate heating-up temperature by attemperating unit.
Below be test:
The fire retardant of test is identical with test fire retardant in the above-mentioned background technology, and paper product specification, material are identical, and different is that the water-based flame-stabilizing temperature in the immersion trough is heated to 90 ℃.The result is:
The U.S. produces long fiber wood pulp brown paper 150g/m
2, penetration period is 3～5 seconds; Homemade high-strength corrugation 150g/m
2, penetration period is 2 seconds; Homemade white board 350g/m
2, penetration period is 10～12 seconds.
The immersion speed of testing on coating machine is:
The U.S. produces long fiber wood pulp brown paper 150g/m
2, coating speed is 45m/min; Homemade high-strength corrugation 150g/m
2, coating speed is the homemade white board 350g/m of 60m/min
2, coating speed is 20m/min.
The anti-flammability test result of above-mentioned paper product behind coating fire retardant on the coating machine is:
Afterflame time is≤1 second, afterglow time≤5 second, and char length≤60 millimeter, oxygen index (OI) is 42.2, smoke density SDR≤6.
Advantage of the present invention:
Improve wetting-out rate than normal temperature dip-coating, increased the broad spectrum activity of flame treatment paper product kind, the insurmountable high WATER REPELLENCY paper product of traditional normal temperature dip-coating has been realized the industrialization high-speed coating, filled up the blank of post processing fire retardant papers suitability for industrialized production.
