Compared with products of the same kind on the market, the sponge abrasive paper is characterized by high elasticity, super softness, stability, durableness and free grinding scratches.
Description
Technical field
The invention belongs to coated abrasive tool technical field, relate to a kind of sand paper, specifically a kind of Sponge sand paper and manufacture method thereof.
Background technology
The polishing abrasive tool used in the market has a variety of, and wherein laminated sand paper is in the majority, forms primarily of base material, viscose glue and abrasive material.Wherein base material adopts cloth or the film of paper material or individual layer mostly, and paper material in use pliability is inadequate, and the easy embrittlement of paper substrate is damaged, and chance water is easily rotten, the equipment of easy scratch polishing during use; And use the cloth of individual layer or film as base material, then easy to wear, in particular for the equipment that surface is comparatively coarse, loss is larger, is not very durable.
Small part sand paper is separately had directly to adopt sponge as base material, but because sponge surface flatness is inadequate, cause abrasive surface also uneven, the sanding and polishing of the higher equipment of surface accuracy cannot be used for, and abrasive material and sponge substrate are directly bonded, be of rude workmanship, technique is simple and crude, and in use procedure, abrasive material very easily comes off damage.Therefore need a kind of surface smoothness higher, quality is more soft, the product that structure is more stable.
Summary of the invention
Technical problem to be solved by this invention is:
How to increase abrasive material and sponge adhesive force, and abrasive material distributed more uniformly, to such an extent as to when polishing abrasive material difficult drop-off and uniform grinding, thus improve service life;
How to increase elasticity and the pliability of Sponge sand paper entirety;
How to improve the surface smoothness of abrasive material, and make this product may be used for the higher product polishing of surface accuracy.
In order to solve above technical problem, the application proposes a kind of Sponge sand paper and manufacture method thereof, and concrete technical scheme is:
A kind of Sponge sand paper, comprise spongy layer, laminating glue-line, primer layer, abrasive material and multiple glue-line, also comprise thin polyurethane rete, the one side of thin polyurethane rete is bonded on spongy layer by least one laminating rubber alloy layer, and abrasive material is by least one deck primer layer and the multiple glue-line of at least one deck covered on primer layer are bonded on the another side of thin polyurethane rete.
The manufacture method of Sponge sand paper of the present invention, comprises following processing step:
(i) apply one deck primer in the one side of polyurethane film, the weight portion of described primer consists of: 100 parts of adhesives, 30 parts of curing agent, 20-50 part diluent, 20-80 part filler;
(ii) carry out planting sand on described primer, plant sand way selection electrostatic sand-planting;
(iii) the polyurethane film after electrostatic sand-planting is carried out drying, drying means is at 80-100 DEG C of dry indoor suspension 0.5-1 hour;
(iv) on the primer of planting sand post-drying, apply the multiple glue of one deck, the weight portion of described multiple glue consists of: the adhesive of 100 parts, 20-80 part diluent, 20-80 part filler;
(v) be cured by the polyurethane film after being painted with multiple glue, curing is at 80-100 DEG C of dry indoor suspension 1-2 hour;
(vi) the opposite side of the polyurethane film after solidification coating laminating glue is made it vacuum abutted with sponge, then drying is carried out, drying means is 90 DEG C-120 DEG C dry indoor suspension solidification 0.5-1 hour, described laminating glue be epoxy resin, acetic acid second rare-ethylene copolymerization emulsions or adhesive for polyurethane.
Like this, by arranging one deck polyurethane film, simple structure can increase abrasive material and sponge adhesive force when planting sand, and abrasive material is distributed more uniformly, thus improves grinding efficiency and effect, abrasive material also difficult drop-off during polishing, improves service life; In addition, by increasing polyurethane film, the elasticity of the entirety of Sponge sand paper and pliability being increased greatly, kills two birds with one stone.
As can be seen here, the present invention scientific and reasonable by increasing polyurethane film and bottom sponge, ingeniously solve Sponge sand paper elasticity and flexible technical problem, turn improve service life simultaneously.
The technical scheme that the present invention limits further is:
Aforesaid Sponge sand paper, wherein abrasive material is the one in silicon carbide layer, Brown Alundum layer, fused alumina zirconia layer, white fused alumina layer or quartz sand layer.
The manufacture method of aforesaid Sponge sand paper, wherein the painting amount of primer and multiple glue is 10-50g/ ㎡;
The manufacture method of aforesaid Sponge sand paper, wherein primer is with in multiple glue, adhesive is epoxy resin, polyurethane, phenolic resins or Lauxite, curing agent is epoxy resin E51 or TDI tripolymer, diluent is toluene, methyl alcohol, ethyl acetate or ether, and filler is stone flour, fine particle calcium carbonate, kaolin or potter's clay.
The manufacture method of aforesaid Sponge sand paper, wherein applies primer layer and multiple glue-line all adopts the pressing mode of rubber roll and steel rider to apply, and realizes the coating of various glue amount by adjusting gap between described rubber roll and steel rider.
Advantage of the present invention is:
Adopt sponge material as base material, compared to laminated sand paper, there is better pliability, the equipment of not easily scratch polishing during use, is applicable to manual grinding furniture, surface of plastic product polishing, polish in auto repair touch-up paint place, the surface treatment of metal rust spots and plastics, has water-fast, acid and alkali-resistance, soft, dry grinding, wet-milling, capable of washing, the feature such as reusable.And, Sponge sand paper compares other similar Sponge sand paper products, have employed special elastic material polyester film, sponge and abrasive material is connected with primer by laminating glue, not only make whole product structure performance more firm, improve the surface smoothness of abrasive material, product is made to may be used for the higher product polishing of surface accuracy, also overall pliable and tough design is met, and in the selection of abrasive material, to polish according to specific needs the material of object, carborundum can be selected, Brown Alundum, fused alumina zirconia, white fused alumina or quartz sand, this type of material expansion coefficient is little, toughness is high, intensity is large, also overall consistent designing requirement is met.
