Description
Technical field
The invention belongs to grain machinery technical fields, and in particular to a kind of rice harvester surface protective coating.
Background technique
Rice is originating in China, and Yangtze River in China basin is with regard to rice cultivation before 7,000 years.According to different methods, rice can divide
For long-grained nonglutinous rice and japonica rice, early rice and middle late rice, glutinous rice and non-glutinous rice.China scientist Yuan Longping makes the research of hybrid rice
Tremendous contribution is known as " father of hybrid rice ".Rice seed, that is, paddy, paddy claim brown rice after sloughing glume, and brown rice is ground
Go rice bran layer that rice can be obtained.Nearly half population in the world is all food with rice.The eating method of rice is varied, has
Rice, congee, rice cake, rice cake, rice wine etc..Rice can also make wine in addition to edible, refine sugar and make the raw material of industry, rice husk, rice
Stalk can be used as feed.China rice main producing region is mainly the Northeast, the Yangtze river basin, Pearl River Delta.Belong to direct economy work
Object.Still the staple food of the one third mankind in the world.
Rice harvester can greatly improve rice harvesting efficiency, and still, when due to rice harvesting, working environment is more
Complexity, and rice harvester is mainly made of metal material processing, so as to cause being easy to corrode, destroys rice harvester what
Can, it reduces the service life, therefore, it is necessary to carry out certain protective treatment to rice harvester.
Summary of the invention
The purpose of the present invention is being directed to existing problem, a kind of rice harvester surface protective coating is provided.
The present invention is achieved by the following technical solutions:
A kind of rice harvester surface protective coating, is made of following component by weight: water-based acrylic resin 75-

(1) a certain amount of talcum powder is taken, 1350 meshes are crossed, solid is added in the ratio that talcum powder and sodium hydroxide mass ratio are 6:1
Sodium hydroxide, ball milling 15min, is then added in reaction kettle, then 6 times of talcum powder quality of deionization is added into reaction kettle
Water is heated to 85 DEG C, with 1500r/min revolving speed stirring 2.5 hours, is then filtered, and drying to constant weight, obtains pretreatment and slides
Mountain flour；
(2) treated pretreatment is placed in plasma reaction kettle, is then passed through gas into plasma reaction kettle
Body makes sodium form talcum powder in the power 550W of plasma reaction kettle gas, under conditions of gas flow is 30-35mL/min
Modification 32min, obtains modified talc powder；
(3) modified talc powder is calcined 1.2 hours, then cooled to room temperature under nitrogen atmosphere protection, then will be after calcining
Modified talc powder evenly spread to mass fraction be 6.5% zinc salicylate solution in, heating water bath to 72 DEG C, heat preservation
Then 50min is filtered, cleaned using deionized water to neutrality, then at 550 DEG C calcine 30min to get.
Further, gas is oxygen and carbon dioxide gas mixture in plasma reaction kettle described in step (2).
Further, the oxygen and carbon dioxide normal pressure lower volume ratio are 1:1.
Further, defoaming agent is organic silicon defoamer.
The present invention has the advantage that the present invention by zinc salicylate modified talc powder, is effectively promoted compared with prior art
Specific surface area, enhances characterization of adsorption, has then carried out modification, by plasma to pretreated talcum powder into
The further processing of row, further improves the specific surface area of talcum powder, so that racemosus shape is presented in modified talcum powder molecule
Tentacle structure, to enhance the bond strength between Multiple components in coating, so improve paint film compactness,
Intensity and thickness improve the use quality of coating, twice-modified processing are carried out with zinc salicylate again later, in talcum powder particle
Outside wrap grafting active group again, improve the surface-active of talcum powder, and then improve modified talc powder in coating
Dispersion compatible properties, with existing coating ratio, protective coating prepared by the present invention can greatly improve cornmill surface anti-erosion
Performance, it is long that coating applies membrane lifetime, applies membrane lifetime compared to conventional acrylic esters coating and improves 3-5 times, and the present invention passes through pair
Paint ingredient is reasonably matched, and the adhesive force of the film of coating can be effectively improved, through the invention after coating coating
The paint layer of formation is tough and tensile, and brightness is high, and acid resistance is strong, and performance is stablized, and is not easy to be corroded, is non-discolouring, adhesive force is very strong, applies
The obstructing capacity of film is very good.
