Abstract
The invention relates to the technical field of lubricant, in particular to water-based lubricant for paper making. The water-based lubricant for paper making is prepared, by weight, by the following raw materials of 10-20 parts of sulfated castor oil, 8-16 parts of hydroxyl silicone oil, 1-5 parts of hydroxyethyl cellulose, 2-6 parts of hydroxy propyl methyl cellulose, 1-5 parts of methyl cellulose, 5-10 parts of polyphenylene sulfide, 8-15 parts of alkyl glycoside, 0.5-3.5 parts of polytetrafluoroethylene, 1-5 parts of sodium diacetate and 30-40 parts of water. According to the water-based lubricant for paper making, the good lubricating effect is achieved, the friction coefficients of coating paper are greatly reduced, the coating adaptability and the smoothness, glossiness and surface strength of finished paper are improved, no carcinogenic ingredient is contained in the raw materials, and environmental protection is achieved; the water-based lubricant for paper making is mainly applied in paper making coatings of the coating paper.
Description
Technical field
The present invention relates to technical field of lubricant, particularly to paper grade (stock) water-based lubricant.
Background technology
Lubricant plays reduction coating coefficient of friction in papermaking paint, improves Gel-coating film spraying, in case
Only manufacture and the back segment of coating paper modifies such as press polish, plant cut wait during produce paper powder, or reduction is coated with paper
Coefficient of friction, the most also have improve coating coating adaptive (as improved the rheological characteristic etc. of coating) and
Improving coating flatness, improve the function of finished paper glossiness, the roll banding simultaneously still preventing applicator roll is existing
As.Paper making lubricant in the market with higher fatty acids salt and oxidation polymer polyethylene is
Main, also include wax emulsion etc., they all have the effect improving coating coefficient of friction.
Chinese invention patent CN1584204A discloses a kind of with OPE for primary raw material system
The technique of standby papermaking coating lubricant agent special.This invention is only limitted to several emulsifying agent and OPE
The emulsion of preparation, complex process.Chinese invention patent CN102733260B discloses paper grade (stock) aqueous profit
Lubrication prescription and preparation method thereof, preparation method comprise the steps: (1) hydroxy silicon oil is added oleic acid,
Organic amine and the compound of water, then drip epoxychloropropane, time for adding 1～3 hours；(2) 50～
80 DEG C are reacted 1～3 hour, are cooled to 20～30 DEG C, it is thus achieved that described paper grade (stock) water-based lubricant.Its
In epoxychloropropane used poisonous, and belong to moderate toxicity, zoopery proves to have potential carcinogenic
Effect, and lubricant resultant effect is the most notable.Therefore research one is without carcinogenic components, lubricant effect
Good paper grade (stock) water-based lubricant becomes critically important.
Summary of the invention
The technical problem to be solved is to provide paper grade (stock) water-based lubricant, and this lubricant has
Excellent lubricating function, has substantially at aspects such as improving into the smoothness of paper, glossiness and surface strength
Effect.
For achieving the above object, the present invention adopts the following technical scheme that
Paper grade (stock) water-based lubricant, is made up of the raw material of following weight portion:
The sulfated castor oil that the present invention uses is anion surfactant, and water soluble has profit
The multiple performances such as wet, infiltration, emulsifying, dispersion, levelling, hydrotropy, lubrication, make lubricant have good
Good lubricity and stability, also have enhanced shine, improve into the glossiness of paper.
Hydroxy silicon oil used in the present invention has good anti-adhesion effects, effectively prevents the viscous of applicator roll
Roller phenomenon.
Hydroxyethyl cellulose, hydroxypropyl methyl cellulose and methylcellulose that the present invention selects can change
The viscosity of kind lubricant, has water retention simultaneously.
Preferably, the particle diameter of politef of the present invention is 0.1～0.5 μm, and particle diameter is suitable,
Ensure the stability of lubricant.The politef of the present invention has antistick characteristic and the thermostability of excellence,
Lubricating coefficient is extremely low, has fabulous lubricity, significantly improves the lubricity of lubricant, effectively prevents
Coating roll banding.Politef and polyphenylene sulfide have the good compatibility, and polyphenylene sulfide is as poly-four
The bonding component of fluorothene, improves the tack of politef, and the two combination can either improve lubrication
The lubricity of agent, additionally it is possible to improve into the surface strength of paper.
Alkyl polyglucoside in the present invention is synthesized by Renewable resource natural fat alcohol and glucose, is
A kind of more comprehensive new non-ionic surfactants of performance.It has conventional nonionic and anion table concurrently
The characteristic of face activating agent, has high surface, good ecological security and intermiscibility, is international
First-selection " green " functional surfactant generally acknowledged, improves paper pulp yield, improves into the smooth of paper
Degree, glossiness, improve the stability of lubricant.
The sodium diacetate of the present invention is preservative, prevents into paper mouldy, and sodium diacetate is mainly by having
Infiltrate through to effect the cell wall of mycete and the interaction of interferases, it is suppressed that the generation of mycete, thus
Reach the function such as high-effect anti-mould, anticorrosion.
Preferably, paper grade (stock) water-based lubricant of the present invention, it is made up of the raw material of following weight portion:
Compared with prior art, the beneficial effects of the present invention is:
The paper grade (stock) water-based lubricant of the present invention has the lubricant effect of excellence, is substantially reduced coating paper
Rub and examine coefficient, improve coating adaptability and become the smoothness of paper, glossiness and surface strength, adopting
Being coated performance test with state's calibration method for paper, the smoothness of the present invention is 978～1042s,
Glossiness is 53%～56%, and surface strength is 2.78～2.82m/s, whiteness 89.3～91.1%, simultaneously
Also prevent the roll banding phenomenon of applicator roll, also there is certain antiseptic effect, without carcinogenic components in raw material,
More environmental protection, lubricant of the present invention is mainly used in the papermaking paint of coating paper.
