Abstract
The invention discloses black corundum composite sand cloth. The black corundum composite sand cloth comprises base cloth. A bottom adhesive layer is arranged on the upper surface of the base cloth. A frosted layer is arranged on the upper surface of the bottom adhesive layer. The frosted layer is black corundum or a mixture of black corundum and brown fused alumina. Meanwhile, the invention discloses a preparation method of the sand cloth. The preparation method of the sand cloth is simple. The black corundum or the mixture of the black corundum and the brown fused alumina serves as the frosted layer. Raw materials are fine, cheap, low in carbon emission, easy to obtain and low in use cost and labor cost. The black corundum composite sand cloth is particularly applicable to grinding and polishing of workpieces which are high in toughness and ductility and difficult to grind; the black corundum composite sand cloth can meet the market demand and has better physical performance; the black corundum can be fully utilized; cost is saved; resource waste is avoided to the greatest extent; the environment is protected; and the black corundum composite sand cloth is suitable for being applied and popularized on a large scale.
Description
Technical field
The invention belongs to emery cloth technical field is and in particular to black corundum is combined emery cloth.
Background technology
Emery cloth is that the cloth of abrasive material or made of paper product are coated, can be fabricated to a kind of grinding, polishing when have flexible, can roll over Grinding tool with crimp property.Because of its distinctive performance, extensively apply in a lot of manufacturings.
Developing rapidly with mechanical industry, the requirement more and more higher to the product of grinding tool, consumption is also increasing, existing Technology in, as abrasive material, Brown Alundum is relatively costly, and during production, carbon emission amount is larger for multiplex Brown Alundum, brown corundum abrasive emery cloth It is primarily adapted for the higher metal of grinding anti-tensile, range has limitation.
Content of the invention
It is an object of the invention to provide black corundum is combined emery cloth.
For achieving the above object, the present invention adopts the following technical scheme that：
Black corundum is combined emery cloth, and including base fabric, base fabric upper surface is provided with primer layer, and primer layer upper surface is provided with frosted layer, Described frosted layer is the mixture of black corundum or black corundum and Brown Alundum.
Preferably, the granularity of described black corundum and Brown Alundum is P24-P2000.
Preferably, in the mixture of described black corundum and Brown Alundum, the mass ratio of black corundum and Brown Alundum is 1: 0-5.
The preparation method of above-mentioned emery cloth, comprises the following steps：
(1), after a surface blade coating mode of treated base fabric being processed, it is dried, obtains the process layer of base fabric；
(2) primer is obtained primer layer with the process layer surface that method attached to roller coat is coated to base fabric；
(3) with electrostatic sand-planting method, primer layer is implanted in frosted, obtain frosted layer；Cured 3-9h at 60-130 DEG C again Obtain final product emery cloth.
Preferably, in described step (1), treated base fabric is to be processed using those skilled in the art's common method Emery cloth；In said method step (3), hardening time is 3 hours, and solidification temperature is 130 DEG C.
In order to reach more preferable effect it is preferred that described base fabric is kraft paper or latex paper；Described primer layer is following material One or more of material：Ureaformaldehyde and its modified resin, phenolic aldehyde and its modified resin, epoxy and its modified resin, acrylic acid and Its modified resin.
