Abstract
The invention discloses a material formula of high performance wear-resisting paper and a method for making the high performance wear-resisting paper. In formula materials, the weight of Al2O3 against the weight of all formula materials is 40 percent, and Al2O3 undergoes the surface activity treatment by using methane chemicals; the making method is characterized in that in the papermaking step, an inclined net paper machine is used, and the distribution of the vacuum degree of the net part meets the sine rule; due to the adoption of the inclined net paper machine and the sine distribution of the vacuum degree of the net part, Al2O3 contained in the wear-resisting paper is obviously in regular distribution, thereby markedly improving the wear resistant property; also because Al2O3 undergoes the surface activity treatment by using methane chemicals, the wet ability and the binding power between Al2O3 in the wear-resisting paper and melamine formaldehyde modified resin are enhanced, thereby avoiding the 'white bloom' phenomenon generated due to the use of the wear-resisting paper in making thermoset decoration laminate boards and improving the cleanness of board surfaces.
Description
Technical field
The invention belongs to pulp technology for making paper, be specifically related to a kind of composition of raw materials and production method thereof of abrasion-proof paper.
Background technology
Abrasion-proof paper is a kind of special overlay paper, is the special-purpose paper of making the heat curing-type decorative laminate, as is used for the production of composite floor board.
The manufacturing technique of abrasion-proof paper has two kinds, is divided into common abrasion-proof paper technology and liquid abrasion-proof paper technology, and present patent application relates to common abrasion-proof paper technology.Known common abrasion-proof paper process using bleaching needle-point leaf pulp through the slurry that looses, low beating defibrination, adds 40% AL that processed again through the surface then
2O
3And retention agent, wet strength agent, use the fourdrinier wire wire multi-cylinder paper machine abrasion-proof paper of manufacturing paper with pulp.The performance of abrasion-proof paper depends primarily on AL in the paper
2O
3Content and distribution situation.Known common abrasion-proof paper process using fourdrinier wire wire multi-cylinder paper machine, its online concentration is 0.5%, the vacuum degree control of forming table is gradually and increases progressively, the abrasion-proof paper of output thus, the AL that it is contained
2O
3Distribution in paper forms at random, irregular seeking, and the poor stability of paper wear-resistant index, the plate face definition during for the manufacture of the heat curing-type decorative laminate is low, easily produces " spending in vain " phenomenon.
Summary of the invention
The object of the invention provides a kind of composition of raw materials and production method thereof of abrasion-proof paper, to overcome the deficiency of existing common abrasion-proof paper production technology, improves the anti-wear performance and the definition performance of abrasion-proof paper.
Technical solution of the present invention is as follows:
A kind of composition of raw materials of high-performance abrasion-proof paper comprises NBKP slurry, AL
2O
3, retention agent, wet strength agent, it is characterized in that: AL in the described batching
2O
3Amount account for 40% of whole batchings; Described AL
2O
3Carry out surface-active-treatment with methane class chemicals; Described AL
3O
2Purity be 99.5%, proportion is 3.9～4.1g/cm
3, powder thickness specification is 53～90um.
The pH value of above-mentioned raw materials prescription behind refining, condiment is 6.5～7.0.
The production method of high-performance abrasion-proof paper comprises and gets the raw materials ready, pulls an oar, prepares burden, copies paper, rewinding, packaging and warehousing operation that it is characterized in that: described machine hand's preface adopts oblique net paper machine, and wet end vacuum distributes by sinusoidal rule.
After the above-mentioned refining operation, the beating degree of slurry is 18～20 ° of SR, and weight in wet base is 8～10g.
In the above-mentioned paper-making process, online concentration is controlled to be 0.06%.
Tiltedly the characteristics of net paper machine are to be fit to long fibre papermaking, become the paper bulk good, and slurry is evenly distributed, and network structure is obvious; Wet end vacuum is distributed with to be beneficial to by sinusoidal rule and reduces stock losses and improve AL
2O
3Distribution on the paper vertical section.Owing to adopt oblique net paper machine and wet end vacuum to distribute by sinusoidal rule, therefore so that the contained AL of abrasion-proof paper
2O
3Distribution in paper presents obvious regularity: AL on the vertical section from upper surface to lower surface
2O
3Density be gradually and successively decrease, at the in-plane AL of paper
2O
3Be evenly distributed; Again because upper sheet surface AL
2O
3Density big and be evenly distributed, so its anti-wear performance obviously improves.In the aforementioned production method, use methane class chemicals to AL
2O
3Carry out surface-active-treatment, be conducive to strengthen the AL in the paper
2O
3And the wetting property between melamino-formaldehyde modified resin and adhesion, thus the phenomenon of " spending in vain " easily produced when avoiding abrasion-proof paper for the manufacture of the heat curing-type decorative laminate, improve plate face definition.
The specific embodiment
Present embodiment is quantitatively being 42g/m
2Paper be example.
Be 42g/m quantitatively
2The batching of high-performance abrasion-proof paper be NBKP slurry, AL
