Description
Technical field
The present invention relates to a kind of speciality paper, particularly relate to a kind of preparation method of stainless steel lining paper.
Background technology
Stainless steel lining paper is in recent years along with domestic and international stainless steel industry is greatly developed, the progressively supporting with it a kind of new special industrial paper for protection stainless-steel sheet product quality liner.Stainless steel lining paper can be divided into according to the difference of stainless steel production technology: the high temperature resistant stainless steel lining paper and the common stainless steel lining paper that is applicable to cold rolled stainless steel sheet that are applicable to the hot pressing corrosion resistant plate.Look into newly through science and technology and learn in July, 2006, the at present domestic existing producer that stainless steel lining paper is provided, but the stainless steel lining paper major part that is provided is from external import, domestic development and production about stainless steel lining paper also has bibliographical information, but fewer.As a kind of high temperature resistant stainless steel lining paper of Henan Provincial Light Industrial Sciences Inst. development, the new big paper industry in Jiangsu group to the production technology of common stainless steel lining paper and the problem that occurs in producing carried out the research report.
Stainless steel lining paper is when cold rolling high-grade stainless steel steel plate, in coiling process in order to prevent friction between the corrosion resistant plate and a kind of dedicated paper of liner.In the stainless-steel sheet production process, because the milling train that runs up tension intensity aborning is big, produce certain frictional force, level and smooth, refraction, brightness to stainless steel product produce very big influence, particularly behind roll bending, because the variation of temperature, humidity, very easily make paper aging, simultaneously because leading indicators such as lining paper tensile strength and smoothness are nonconforming, when debatching, often tear because of lining paper appears in meeting, phenomenon such as breakage, cause between the steel plate directly that contact produces friction, influence product quality.For this reason, stainless-steel sheet producer is more and more higher to index requests such as the tensile strength of stainless steel lining paper, smoothness, cleannes.
Summary of the invention
For solving stainless-steel sheet in the production process that runs up, because of lining paper intensity, smoothness, the not enough low problem of product percent of pass that causes of tear-resistant degree index, purpose of the present invention just provides a kind of have high strength, tear-resistant, super level and smooth, abrasive, the low quantitative stainless steel lining paper that has resistance to elevated temperatures simultaneously.
The present invention solves described problems of the prior art by the following technical solutions, and realizes purpose of the present invention:
The white wood pulp adds chemical assistant, copies operations such as paper, press polish, coil paper through hydraulic pulping, three sections desanding, shiny beating, segmentations.Its technological process of production is seen accompanying drawing.
High strength, tear-resistant, super production control main points level and smooth, the abrasive stainless steel lining paper are: the one, and totally-enclosed, cleaner production; The 2nd, select proper raw material; The 3rd, take the staple fibre shiny beating mode that suits, keep fibre length in 1.2～2.0mm scope; The 4th, the use of effective auxiliary agent strengthens fiber combining power in the paper, changes the wet end structure, to improve the tear-resistant degree of paper pull intensity, tensile factor and paper.
Technical essential in the production:
(1) slurry is selected.For guaranteeing that stainless steel lining paper has enough intensity, selecting white wood pulp for use is raw material, wherein: the white needle wood pulp: white hardwood pulp=70%～80%: 30%～20% (percentage by weight).The white needle wood pulp is selected sulfate process production for use, requires whiteness more than 90, surperficial immaculate, 1.0～5.0mm
2Dust is not more than 350mm
2/ 500g, moisture content are less than 7%, and fibre length on average is not less than 3.4mm, burst index＞5.0KPam
2/ g, tensile index＞80Nm/g, tear index＞6.5mN.m
2/ g.The white hardwood pulp can be sulfate process, sulphite process, and method production such as alkaline process.The broad-leaved slurry requires: fibre length 0.65～1.2mm, the broad-leaved slurry mainly plays filling, the effect of reducing cost.
(2) three sections desanding purify.Adopt three sections desanding to purify in the production, fully remove impurity such as iron filings that slurry contains, sand grains, can effectively improve the cleaning to stainless steel lining paper, the quality requirements of light.
(3) adopt the staple fibre shiny beating.Reasonably the making beating mode keeps the enough length of fiber, is high strength, tear-resistant key.Adopt the staple fibre shiny beating, make fiber height divide silk, suitable cut-out is arranged again, it is even to make into paper, and soapy feeling is arranged, and intensity is big.Its beating consistency 4～4.5%, 58～63 ° of SR of pulping beating degree, weight in wet base 5～7g, fiber 1.2～2.0mm.Wherein defibrination selects for use 330 mill basalt stone abrasive discs to carry out defibrination, and selecting the purpose of stone mill is to make fibre cutting few, keeps fiber that enough length is arranged, and to reach stainless steel lining paper better tear-resistant degree is arranged.
(4) chemical assistant selects for use and adds requirement.This is another key link during the high-performance stainless steel lining paper is produced.
Being used of paraffin wax emulsions and cationic starch, alkyl diene Chiung dimer (being called for short AKD) is to improve performances such as paper strength, brightness, WATER RESISTANCE, moisture retention, flatness and anti-pitch trouble.Addition is (accounting for the percentage of wood pulp): paraffin wax emulsions 5～20%, and cationic starch 0.5～1.0%, AKD 0.5～1.0%.Be metered into respectively at pulp storage tank.
Silicone emulsion, to improve the preserving moisture of finished product, anti-aging, brightness plays a major role, and is used with paraffin wax emulsions, strengthens the resistance to elevated temperatures of lining paper.Addition is (accounting for the percentage of wood pulp): silicone emulsion 1.0～2.0%.Silicone emulsion is metered at stuff box.
Cationic polyacrylamide (be called for short CPAM), cationic polyamide epoxychloropropane (being called for short PAE) be gain in strength, the important means of tearability, bursting strength.Addition is (accounting for the percentage of wood pulp): CPAM 0.3～0.5%, PAE0.25～0.75%.Add in the header box before copying paper.
The stainless steel lining paper that adopts the present invention to produce, main performance index is: quantitative 40 ± 2g/m
2, the positive 53m/s of smoothness, more than the reverse side 42m/s, surface strength 〉=13.5a, bursting strength reaches 〉=250Kpa, and folding strength is not less than vertical 154 times, horizontal 46 times.This stainless steel lining paper is applied in hot rolling or the cold rolled stainless steel sheet production, technology lining paper at coiling process, strictness test and use proof through Tianjin stainless steel factory, hot continuous rolling subsidiary factory of Taiyuan iron and steel group, lining paper is functional, steady quality meets the production requirement of high-grade stainless steel plate fully.Product of the present invention successfully solved stainless steel lining paper intensity difference, easily tear, smoothness, cleannes are poor, influence the problem of stainless steel product quality in the use, have solved the difficult problem that stainless steel lining paper can only be produced heavu weights simultaneously.The product of being produced compares with external product of the same type, on item indexs such as tensile strength, smoothness, folding strength bigger advantage is arranged all.
