Abstract

The invention discloses an environment-friendly type resin grinding wheel without containing sulfur. The environment-friendly type resin grinding wheel comprises, by weight, 50%-60% of white corundum, 15%-25% of mono-crystalline fused alumina, 2%-5% of phenolic resin liquid, 7%-10% of phenolic resin powder, 1%-13% of white fused alumina micro-powder and1%-13% of brown fused alumina micro-powder. The environment-friendly type resin grinding wheel is simple in components and easy to prepare, does not have special requirement to a shaping technology, and can implement production through using a normal technology. The manufactured grinding wheel is sharp in cutting, single blade cutting only needs 4s-5s, the service life of cutting is more than 30% longer than that of the same kind of grinding wheel of a market famous band, and most important, no sulfur dust is produced when cutting operation is conducted, thus working environment is improved, and no damage is caused to the physical and mental health of an operator. Besides, the white fused alumina micro-powder and the brown fused alumina micro-powder are used as filled materials, the white fused alumina micro-powder and the brown fused alumina micro-powder are still have grinding ability in a grinding wheel origination, and thus the environment-friendly type resin grinding wheel is favorable for improving cutting efficiency and improves the quality of the section of a cutting opening.

Description

The environmental protection type resin emery wheel

Technical field

The present invention relates to a kind of grinding materials and grinding tool, particularly a kind of environmental protection type resin emery wheel of not sulfur-bearing composition.

Background technology

The emery wheel kind that is used in the market cutting stainless steel is a lot, all contains troilite powder (FeS in the emery wheel component of these kinds under the prior art condition ₂).Troilite powder mainly plays two effects greatly in grinding wheel organization, is at first to make filler to use, and next utilizes the lubricity of sulphur to improve cutting performance.But troilite powder has very strong reducing property under the uniform temperature condition, and emery wheel certainly leads to heat in metal cutting when being used for cutting stainless steel, and the troilite powder oxidation that heat in metal cutting is accelerated in emery wheel generates SO ₂SO ₂Be acidic materials, cause stainless steel otch section by SO on the one hand ₂Pollute and induce electrochemical corrosion.On the other hand, SO ₂Produce the strong impulse smell and pollute on-the-spot air ambient, especially under the relative closure environment, continue the SO that cutting stainless steel produces ₂The gas people that extremely chokes sometimes smokes to such an extent that operator's eyes are opened not open.Operation except operator's health is damaged, also is difficult for obtaining satisfied cut quality under the environment of this severe contamination.

Summary of the invention

The present invention is mainly for the deficiency that contains troilite powder in prior art products, propose a kind of component rationally, configuration easily, the environmental protection type resin emery wheel of sulfur-bearing not, this emery wheel does not produce toxic odor when being used for cutting stainless steel and cutting efficiency is high.

The present invention is achieved through the following technical solutions technical goal.

The environmental protection type resin emery wheel, its improvements are: the components based on weight percentage amount is as follows:

White fused alumina 50%～60%

Single alundum 15%～25%

Liquid phenolic resin 2%～5%

Phenol-formaldehyde resin powder 7%～10%

White fused alumina micro mist 1%～13%

Brown fused alumina micropowder 1%～13%.

In said components, to be respectively the granularity of white fused alumina F36～F46, single alundum F36～F46, phenol-formaldehyde resin powder F200～F220, white fused alumina micro mist and brown fused alumina micropowder be F380～F400 to the granularity of granular material.

The present invention compared with prior art has following good effect:

1, sulfur-bearing not in component, do not produce the sulfur-bearing flue dust during cutting operation, improves working environment, to the physically and mentally healthy not damage of operator;

2, sulfur-bearing not in component, the SO that the otch section is not residual ₂, do not produce the electrochemical corrosion condition;

3, be furnished with white fused alumina micro mist and brown fused alumina micropowder in component, not only can make filler but also have certain grinding capacity, help to improve cutting efficiency and otch cross section quality.

The specific embodiment

The environmental protection type resin emery wheel, do not contain troilite powder in component, concrete components based on weight percentage amount is as follows: white fused alumina 50%～60%, single alundum 15%～25%, liquid phenolic resin 2%～5%, phenol-formaldehyde resin powder 7%～10%, white fused alumina micro mist 1%～13% and brown fused alumina micropowder 1%～13%.The granularity that the granularity of said components particle is respectively white fused alumina F36～F46, single alundum F36～F46, phenol-formaldehyde resin powder F200～F220, white fused alumina micro mist and brown fused alumina micropowder is F380～F400.

Further verify the present invention below by embodiment, embodiment component deal allocation list (seeing Table 1), cutting performance contrast table (seeing Table 2).Environmental protection type resin emery wheel of the present invention is the same with Comparative Examples emery wheel size, unified is Φ 105 * 1.0 * 16, make the cutting contrast test under same working condition, cut substrate is that the trade mark of Φ 8mm is 304 stainless steel bars, stops when being cut to the remaining Φ 35mm of grinding wheel diameter.

Table 1: implement component deal allocation list

Table 2: cutting performance contrast table

Component of the present invention is simple, configuration is easy, and moulding process is not had specific (special) requirements, can realize producing with conventional moulding process.Verify by above-described embodiment, the present invention cuts sharp, and the hilted broadsword cutting only needs 4S～5S, cutting life is longer more than 30% than the similar emery wheel of market famous brand name, most importantly do not produce the sulfur-bearing flue dust when being cutting operation of the present invention, improve working environment, to the physically and mentally healthy not damage of operator.In addition, the present invention uses the white fused alumina micro mist and brown fused alumina micropowder is made filler, and these micro mists still have grinding capacity in grinding wheel organization, be conducive to improve cutting efficiency, improve the otch cross section quality.
