Abstract
The invention relates to pulp based on epoxy soybean oil and a gravure wiping roller prepared from the pulp. The pulp consists of the following components in part by mass: 5 to 60 parts of 1069, 10 to 60 parts of Psh-10, 0.01 to 40 parts of epoxy soybean oil, 10 to 40 parts of dioctyl phthalate, 1 to 3 parts of fumed SiO2, 1 to 6 parts of calcium carbonate, and 4 to 20 parts of X980, wherein the 1069 is polyvinyl chloride resin produced by a micro suspension method, the Psh-10 is polyvinyl chloride resin produced by an emulsion method, and the X980 is trimethylolpropane trimethylacrylate. The invention aims to provide a formula of the gravure wiping roller based on the epoxy soybean oil. Abrasion resistance, ageing performance, finishment and mechanical property of the surface of the wiping roller are promoted, and irritant gas and consumption of heavy metal compounds in the processing process are reduced.
Description
Technical field
The present invention relates to the gravure wiping roller based on epoxy soybean oil type slurry and preparation thereof.
Background technology
The epoxy soybean oil ep-type material that to be soybean oil make through oxidation, the existence of epoxy group(ing) makes this material have good heat-resisting, photostabilization, and volatility is low, and resistance to extractable is good and have satisfactory stability, resistance to materialization and a weather resisteant.Engraving gravure wiping roller is (with the mutual extrusion friction of forme of 80 degree high temperature in high pressure (100-200kg/cm2), high heat, in the wiping version liquid of 40-50 degree, invade bubble), use under high corrosion (being subject to wiping the corrosion of strong base solution in version liquid), the high severe environment that rub, require wiping roller material to there is good resistance to physical and chemical performance.
Summary of the invention
The object of this invention is to provide a kind of based on epoxy soybean oil type engraving gravure wiping roller formula, when promoting wear resistance, aging resistance, smooth finish and the mechanical property on wiping roller surface, reduce the generation of course of processing moderate stimulation gas and the use of heavy metal compound.

A gravure wiping roller prepared by the slurry based on above-mentioned, comprises gravure wiping roller body, and its special character is: the outside surface of described gravure wiping roller body is provided with slurry film, and the composition of described slurry film is:
Wherein: 1069 polyvinyl chloride (PVC) RESINS for microsuspending method production, Psh-10 is the polyvinyl chloride (PVC) RESINS that emulsion method is produced, X980 is trimethylolpropane trimethacrylate.
Advantage of the present invention is:
1, the epoxy soybean oil material that this slurry adopts is a kind of environmental-friendly plant plasticizer oil and stablizer, reduces the generation of course of processing moderate stimulation gas and the use of heavy metal compound.
2, the epoxy soybean oil that this slurry is used has good physical and chemical performance, good stability, and the slurry of preparation is suitable for being coated with sizing technique.
3, the wiping roller plasticizing effect that the present invention makes is good, surface-brightening, and wear resistance, mechanical property all has a certain upgrade.
4, the wiping roller that the present invention makes is wiped in version liquid 10 days mechanical propertys without considerable change 80 ℃ of alkalescence.
5, the wiping roller that the present invention makes can shorten the board grinding roller time, reduces machining number of times;
Embodiment
The present invention is mixed with uniform slurry by polyvinyl chloride, epoxy soybean oil, dioctyl phthalate (DOP), gas phase sio2, calcium carbonate, X980 according to certain ratio, by vacuum stirring, stainless steel, filter, adopt the complete processing of coating starching to be made into wiping roller, by using on the machine, respond well, wear resistance, aging and the mechanical property of raising wiping roller.
The index request of epoxy soybean oil of the present invention is as follows:
In formula, add according to a certain percentage epoxy soybean oil as softening agent and stablizer, increase the content of X980, polyvinyl chloride is that emulsion method and microsuspending method are produced the paste resin that molecular weight is high, particle diameter is little that collocation is used, its molecular weight ranges Mn (50000-70000), Mw (200000-400000), Mz (1000000-2000000), particle size range (0.5-50um) and (0.5-5um) two kinds.
This slurry adopts the machining process of coating starching, the slurry of preparation is 180-190 ℃ of plasticizing, and through turning technique for grinding, the wiping roller surface-brightening of making, roughness reduce, abrasion volume reduces more than one times, in alkalescence, wipes in version liquid aging 10 days without considerable change.
