Description
Technical field
The invention belongs to coated abrasive tool field, relate to a kind of cloth base class back of the body suede coated abrasive tool product and manufacture method thereof.
Background technology
At the bonding one deck flannelette in the coated abrasive tool product back side of general base material and the back of the body suede product formed, extensively be applied to surface grinding and the polishings such as various metal, carpenter, automobile finish, coordinate electronic and pneumatic tool use, there is the advantages such as grinding efficiency is high, dust is little.In the manual process transformed to mechanization gradually, electronic increasing with pneumatic tool, high to cost performance and that efficiency is high coated abrasive tool product has potential great demand amount.
At present, back of the body suede product more on market mostly is the coated abrasive tool product adopting paper substrate, plastics, grid cloth base material, but often kind of product has respective application and application characteristic.Price and the moderate performance of back of the body suede sand paper product are widely used, but there is not water-fast, shortcoming such as the back of the body suede and paper substrate is easily peeled off, the easy leafing of paper substrate etc., limit its application; The flatness of back of the body suede plastic product is very good, and has certain rigidity, and grinding efficiency is higher, but its price is higher, is mainly applied to the field of milling of the fine surfaces such as automobile finish repairing; Although back of the body suede grid series products has higher and chip removal performance, there is large, that effectively milling area the is little shortcoming of product fragility.In order to solve the shortcoming of coated abrasive tool product of above paper substrate, plastics, grid cloth base material, the back of the body suede emery cloth product of fabricbase base material is adopted to be developed, although but resistance to water, cementability that existing back of the body suede emery cloth series products has had, there is the deficiency that cost is high, surface smoothness is slightly poor and anti-blocking performance is slightly poor.In order to solve the shortcoming that back of the body suede emery cloth series products cost is high, surface smoothness is slightly poor and anti-blocking performance is slightly poor, there is following technical scheme in prior art: directly use flannelette to be base material, carry out the manufacture of coated abrasive tool after process, save multiple suede operation; Under the prerequisite meeting performance requirement, the base materials such as paper substrate, non-woven fabrics, plastics, grid cloth are used to carry out part compound and reach the requirement of high fracture strength; But above technical scheme is all not yet in effect solves the deficiency that back of the body suede emery cloth series products cost is high, surface smoothness is slightly poor and anti-blocking performance is slightly poor.
Summary of the invention
Technical problem to be solved by this invention is, overcome the shortcoming of prior art, a kind of cloth base class is provided to carry on the back suede coated abrasive tool product and manufacture method thereof, can obtain the cloth base class back of the body suede coated abrasive tool product with better surface smoothness, anti-blocking performance, support hardness, resistance to water and cementability, and production cost is low.
The technical scheme that the present invention solves above technical problem is:
A kind of cloth base class back of the body suede coated abrasive tool product, comprise flannelette and emery cloth, emery cloth comprises fabricbase base material and abrasive material, villous is drawn in the front of fabricbase base material, fine hair adhesive is carried out effectively cover forming smooth composite bed, abrasive material is connected on composite bed by primer with multiple gluing, and flannelette is bonding with the reverse side of fabricbase base material by adhesive.
A kind of cloth base class back of the body suede coated abrasive tool product, comprise flannelette and emery cloth, emery cloth comprises fabricbase base material and abrasive material, the obverse and reverse of fabricbase base material all has fine hair, the fine hair adhesive of obverse and reverse carries out effectively covering forming smooth front composite bed and reverse side composite bed, abrasive material is connected on the composite bed of described front by primer with multiple gluing, and flannelette is bonded on described reverse side composite bed by adhesive.
A kind of manufacture method of cloth base class back of the body suede coated abrasive tool product,---the manufacture of emery cloth product---compound of emery cloth and flannelette---pore-creating and cut packaging is carried out: the process of fabricbase base material by following operation, wherein the manufacture of emery cloth product is undertaken by following operation: be coated with primer---electrostatic sand-planting---dry---coated glue---dry---flexure, is characterized in that in rolling---solidification---: the process of described fabricbase base material is undertaken by following operation:
(i) heavily 180g/m is less than to grammes per square metre over dry
2fabricbase base material carry out single or double napping mechanically, make single or double form uniform fine hair, the height of fine hair is less than 100 μm;
(ii) washing stretching is carried out to the fabricbase base material after napping, control percentage elongation at 1-10%;
(iii) dipping, blade coating, roller coat or spraying method are crossed all to the fabricbase base material after washing stretching and adhesive is coated with to fine hair, make adhesive effectively cover fine hair and ensure surfacing;
(iv) drying and trimming are carried out to the fabricbase base material after gluing.
Like this, by carrying out napping at fabricbase substrate surface, the uniform tapetum formed, effectively covered by adhesive again and form the smooth composite bed of one deck, hardness and surface smoothness can be supported preferably for fabricbase class back of the body suede coated abrasive tool product obtains, thus its anti-blocking performance can be improved, improve further the adhesive property of itself and abrasive material; In addition, effectively covering fine hair by adhesive also can make cloth base class back of the body suede coated abrasive tool product obtain good elasticity; Owing to using the base material of cloth, there is again excellent resistance to water and cementability, thus it is low to obtain production cost, there is the cloth base class back of the body suede coated abrasive tool product of better surface smoothness, anti-blocking performance, support hardness, resistance to water and cementability.
The technical scheme that the present invention limits further is:
Aforesaid cloth base class back of the body suede coated abrasive tool product, the grammes per square metre over dry of fabricbase base material is heavily less than 180g/m
2.The fabricbase base material that the present invention adopts grammes per square metre lighter, the grammes per square metre of base material is lighter, and cost is less, and concave-convex surface difference is less, but the adhesive property on surface also can be caused to decline simultaneously; The present invention is by carrying out napping at fabricbase substrate surface, the uniform tapetum formed, tapetum is effectively covered by adhesive layer and forms the smooth composite bed of one deck, ensure that the flatness of fabricbase substrate surface, the adhesive property of fabricbase substrate surface can be improved, while reducing costs, turn improve performance, kill two birds with one stone.
