Abstract
The present invention discloses a method for producing composite paper. Paper-making equipment is utilized; non-woven making material is used as base material, the plant fiber of wood pulp and cotton pulp is used as face paper, and the base material and the plant fiber are combined by a water-jetting method to produce the composite paper. The present invention overcomes the defects of paper that the water absorption is good, but the wet strength is poor; the wet strength is good, but the water absorption is poor. The hair of composite paper does not easily fall off in a wet state, and the dry tensile strength, the wet tensile strength and the tearing degree of the composite paper largely exceed those of common paper; the composite paper can use different plant fiber layers and non-woven making base material for compositely producing the material of various kinds of performance and various purposes, and the use field of the products is enlarged. The composite paper has the advantages of low manufacture cost, large productivity, various breed changes, etc. compounding and surface processing can be completed on single equipment, and thus, the composite paper also has the advantages of simple production, convenience, high efficiency, low energy consumption, etc. The water used for water jetting can be used for making the paper; thus, the present invention has the characteristics of cost reduction for water processing, water saving and pollution reduction.
Description
Technical field
The present invention relates to the composition of slurry or paper pulp, relate in particular to a kind of production method of composite sheet.
Background technology
After existing paper absorbs water, the intensity variation, if paper wet strength is increased, its water absorbing properties will descend so.How to make existing well dried, the wet strength of paper, good water absorbing properties is arranged again, this is the contradiction of a pair of very difficult solution.
Summary of the invention
The production method that the purpose of this invention is to provide a kind of composite sheet,
It is to utilize paper making equipment, is base material with the nonwoven material, and wood pulp, cotton pulp string are that facial tissue combines the two by the method that water stings, and produce composite sheet.
The concrete production method of composite sheet is: the pulpboard that wood pulp, cotton pulp string are made, put into hydrabrusher, add the abundant size degradation of water, make concentration and be 3～5% paper pulp, put into reserve pit, with stock pump paper pulp is delivered to color pond dyeing, add coloring agent, concentration is 0.1～0.3%, and color-fixing agent, consumption is 1～3% of an oven dry stock amount, making mass dryness fraction through paper machine forming web processed is 20～25% wetted surface paper, with paper carrying roll wetted surface paper is drawn, that emit with unreeling machine quantitatively is 30～60g/m
2Nonwoven substrates, with pressure roller the two is fitted tightly, be 12～16Mpa with pressure again, the aperture is 0.1-0.2mm, pitch-row is that the double liquid drugs injection of 1-2mm is implanted the string of wetted surface paper in the nonwoven substrates, be that the suction flat box of 2040～3061mm water column is inhaled the moisture in the composite sheet and gone through vacuum again, make the mass dryness fraction in the composite sheet reach 35-40%, dry through 100～140 ℃ drying cylinder multiple tracks again, to mass dryness fraction be 85-90%, handle through the double roller coating machine surface coated, it is 1～3% water repellent that coating fluid is selected concentration for use, fire retardant, the antistatic additive material, after the coating again through 140～160 ℃ oven for drying.
Described string is wood pulp, cotton pulp, jute pulp string.Nonwoven material water thorn, acupuncture, spunbond, hot rolling or meltblowing method are made.
The present invention has overcome the paper good water absorption but wet strength is poor, the good but shortcoming of water imbibition difference of wet strength; Compound back paper is difficult for falling hair under the hygrometric state situation; The doing of composite sheet, wet tensile (strength), tearability all substantially exceed general paper; Composite sheet has merged the dual performance of paper and nonwoven material, be single paper and nonwoven material can't be obtained; Composite sheet can be produced multiple performance with not kindred plant fibrage and nonwoven substrates are compound, and multi-purpose material enlarges product and uses the field; Advantages such as composite sheet has low cost of manufacture, and production capacity is big, and variety variations is many; On single equipment, can finish compound, surface treatment, have and produce simple, convenient, high, the low power consumption and other advantages of efficient; Water after the water thorn is used can be used for papermaking, reduces cost of water treatment greatly, and using water wisely reduces and pollutes;
