The invention has the beneficial effects as follows:
The present invention has spiral slot in the surface configuration of emery disc, spiral slot is when emery disc high speed rotating, emery disc flour milling is with the grindstone dust of generation in the grinding of workpiece with sand formation cuttings under the influence of centrifugal force, splash from spiral slot and discharge, simultaneously, spiral slot can produce cooling vortex wind, reduce flour milling and the temperature of processing workpiece, spiral slot not only makes sand formation cuttings and grindstone dust be difficult to stick on flour milling and processing surface of the work, and reduce flour milling and the temperature on surface of the work, compared with existing emery disc, grinding usefulness is high.
Emery disc in the present invention is multiple structure, containing two abrasive materials of two substrate layers, first abrasive material is in the front portion of the first base material, after first abrasive material has ground, first substrate layer is owing to being that vulcan fibre comes off the most therewith, second abrasive material can continue to carry out grinding, is equivalent to this emery disc and has twice grinding function, and then not only increases the efficiency of grinding and use cost has obtained reduction at double.
The emery disc commonly used at present, substrate layer is typically all and uses vulcan fibre unilateral, the substrate layer being and sand face poor adhesion, the abrasion resistance in sand face is the highest, using effect is undesirable, the second substrate layer in the present invention is by non-woven fabrics, fiberglass gridding cloth and polyester-cotton blend composition, it is followed successively by non-woven fabrics from top to bottom, polyester-cotton blend, fiberglass gridding cloth, non-woven fabrics overlaps each other, for the most single vulcan fibre used compared to common sand tray is as matrix, intensity is bigger, for using single fiberglass gridding, toughness is preferable, and toughness can preferably keep consistent with intensity, avoid that local stress is excessive and that produce emery disc such as ruptures at the phenomenon.
In emery disc of the present invention, the circumferencial direction of the second substrate layer is provided with circular mill emery stick around this emery disc, the sand formation cuttings sputtered when can intercept work when emery disc works and grindstone dust, avoid hurting staff, stop due to circular mill emery stick, sand formation cuttings and grindstone dust will not splashes due to action of gravity, fall from the volume bottom of sand table, it is ensured that the safety of staff.
nullBinding agent in coated abrasive tool is typically by base material、Firming agent or catalyst、Filler、Solvent and auxiliary agent composition，Because single component tends not to meet the demand on using，Need to mix various components，The requirement of proper adhesive performance is obtained through certain physics or chemical action，But it is low generally to there is adhesive strength in existing binding agent、Poor toughness、It is difficult to machine-shaping、Water proofing property is poor、Corrosion-resistant，Heat-resisting quantity is weak，Thus cause its tensile strength of coated abrasive tool produced little，Wearability is weak，Easily affected deforming of generation by temperature and humidity，Make its use time short，The defects such as grinding effect difference，Binder Composition in the present invention adds the inorganic compound conductive material with electric action，Emery disc is made to be improved than the electric conductivity of traditional emery disc，Its grinding process can effectively be stopped the generation of electrostatic and affect its ground effect，There is anti-static effect，And adhesive capacity is strong，Well abrasive material is sticked on substrate layer.
Substrate layer is first processed by the present invention when producing this emery disc, first substrate layer has carried out shaping, and the first substrate layer, through water logging Hui Run, is allowed to plasticity and strengthens, place at ballast above after water logging, on the one hand can balance its moisture, on the other hand be allowed to tentatively flatten, balance is dried places 3-5 days, it is to make the moisture in the first substrate layer and environmental balance, to ensure not redeformation after flattening, the first substrate layer after treatment is unlikely to deform, can more preferable bonded abrasive；
nullTo the coating being coated with high temperature on the second substrate layer，The coating of high temperature uses roller press type to substitute manual bonding，Shorten the production cycle，Improve production efficiency，Film-forming resin in high-temperature coatings is the mixture of glycolylurea epoxide resin and methyl phenyl silicone resin，Glycolylurea epoxide resin is the new special epoxy resin containing hydantoin heterocycle that is glycidated by glycolylurea or derivatives thereof and that obtain，Glycolylurea epoxide resin viscosity is low，There is good electrical insulation capability、Thermostability、The characteristic such as weatherability and wearability，Coating is made to have good thermostability、Wearability and weatherability，The mixture of two kinds of resins avoids respective shortcoming，Make the best use of the advantages the advantage of both sides，Better，The coating of high temperature can protect the second substrate layer when the second abrasive material abrasion，There is good high-temperature resistant result，Extend the service life of the second substrate layer，Reduce cost，The incorporation of high-temperature coatings rare earth elements is as extending water、The corrosive mediums such as ion are diffused into the path of the second substrate layer,The second substrate layer can be made to open with corrosive medium isolation，The adhesion with binding agent can be strengthened simultaneously，Thus put forward the integral protection performance of the second substrate layer.
