Description
Technical Field
The invention belongs to the technical field of abrasive cloth coating preparation, and particularly relates to a preparation method of a high-temperature-resistant abrasive cloth coating for metal polishing.
Background
The abrasive cloth product belongs to a high-grade grinding coated grinding tool and is a matched tool necessary for the development of the manufacturing industry. The abrasive cloth can polish the surfaces of wood, metal and the like, so that the surfaces of the abrasive cloth are smooth and flat, and most of traditional abrasive cloths are applied to polishing of metals such as stainless steel and the like in the form of abrasive belts. The existing coated abrasive tool products have multiple varieties and wide application. With the development of technology, new workpiece or material to be polished is produced, and the polishing tool and material to be polished are matched with the requirement. Meanwhile, the new material can also become one of the raw materials of the coated abrasive product, and is developed into a new variety of the coated abrasive product, thereby realizing new performance or new application in the grinding process. The existing abrasive cloth can generate a large amount of abrasive dust and heat in the polishing process, so that the service life of an abrasive belt is greatly influenced, and the surface of a workpiece is extremely easy to burn when the temperature is high.
Disclosure of Invention
In order to solve the problem in the polishing process, a layer of metal polishing special super-coating is added on the surface of the abrasive cloth, a heat absorber and a lubricant are added in the super-coating formula, the temperature during polishing is reduced, abrasive dust generated during polishing can be taken away along with the super-coating, the falling speed of the coating is controlled at the most proper speed by adjusting the proportion of the adhesive and the heat absorber, and the service life of the abrasive cloth is prolonged while the polishing effect is ensured.
In order to achieve the above object, the present invention provides the following technical solutions:
a preparation method of a high-temperature-resistant abrasive cloth coating for metal polishing comprises the following steps:
(1) Weighing raw materials of the high Wen Shabu-resistant coating, specifically, the raw materials comprise the following components in parts by weight: 0-30 parts of solvent, 0-10 parts of emulsifier, 0-5 parts of defoamer, 10-40 parts of heat absorber, 10-40 parts of lubricant, 10-40 parts of thixotropic agent, 1-5 parts of modified titanium dioxide, 10-20 parts of binder and 10-20 parts of hardener;
(2) Sequentially pouring the binder and part of the solvent into a stirring tank, stirring while pouring, and uniformly mixing to obtain a component A;
(3) Sequentially pouring the heat absorbent, the lubricant, the hardener, the modified titanium dioxide and part of solvent into a stirring tank, stirring while pouring, and uniformly mixing to obtain a component B;
(4) Sequentially pouring the emulsifying agent, the defoaming agent, the thixotropic agent and the residual solvent into a stirring tank, stirring while pouring, and uniformly mixing to obtain a component C;
(5) Mixing the component A and the component B, stirring uniformly, adding the component C, mixing, and stirring uniformly to obtain the high-temperature-resistant abrasive cloth coating for metal polishing.
Solvent: the solvent is water, and mainly plays a role of solvent, so that the materials are uniformly dispersed.
The amounts of the solvents used in the compounding of the component A, the component B and the component C are not particularly limited, and may be appropriately selected according to the amounts of the remaining components.
Emulsifying agent: the emulsifier selected by the invention is one of sodium alkyl sulfate, sodium secondary alkyl sulfate, fatty alcohol polyoxyethylene ether and alkylphenol polyoxyethylene ether, and has the main function of promoting the emulsification and dispersion of the heat absorber and the lubricant in water to form uniform paste.

And (2) a binder: the adhesive selected by the invention is one or more of epoxy resin, modified polymer resin, acrylic resin and polyurethane resin.
Hardening agent: the invention selects one of polyamide, methyl tetrahydrophthalic anhydride and isocyanate. The adhesive and the hardener act together, the function of the adhesive is to attach the coating on the abrasive cloth to form a continuous film, the type and the proportion of the adhesive selected need to be matched well, the coating can be ensured to fall off synchronously with abrasive dust during polishing, if the falling off is too fast, the abrasive cloth has a low service life, the falling off is too slow, and the anti-blocking effect is poor.

The polishing process of metals is a continuous exothermic process, and the inventors found that the adhesive using a single resin has poor heat resistance, and particularly, the polishing life is affected in order to ensure the stability of the polishing effect by melting and falling off the absorbent in the later stage of use. The adhesive obtained by compounding various resins has stronger thermal stability, good heat resistance in the polishing process and difficult softening in the grinding heat generating process, reduces the blocking phenomenon and prolongs the grinding service life. The effect of changing the type and the proportion of the resin is not ideal. The inventors have unexpectedly found that when the binder is compounded of acrylic, polyurethane and epoxy resins and a modified polymeric resin in specific proportions, the mid-temperature (25 ℃) cure time of the coating is improved. It is hypothesized that under these conditions the network structure is more readily and rapidly formed within the coating system of the present invention. But the curing time at low temperatures is not ideal.
The auxiliary agent is fatty alcohol polyoxyethylene ether AEO-9. Purchased from Shandong Weren chemical Co.
The silane coupling agent is a silane coupling agent KH550.
Further, the preparation method of the modified titanium dioxide comprises the following steps: the mass ratio is 1-1.1:1.2-1.5: mixing 100 polyacrylic acid, propylene glycol and titanium dioxide, and reacting for 3-4 hours at 60-65 ℃; heating to 70 ℃, regulating the pH value to 4, adding a silane coupling agent accounting for 1.2-1.3% of the mass of the titanium white powder, reacting for 34 hours, filtering and washing with ethanol to obtain the modified titanium white powder.

The modified titanium dioxide is added, so that the coating can be completely surface-dried at a low temperature (10 ℃). The modified titanium dioxide is suspected to lead the adhesive to have proper viscosity which is beneficial to low-temperature curing through adjusting action, and simultaneously has the same action on the hardener, so that the dynamics of resin curing can be adjusted, and the curing reaction can be rapidly carried out even at low temperature.
Compared with the prior art, the invention has the advantages that:
(1) The heat absorber added in the super coating layer has a melting point between 300 and 700 ℃ and is composed of at least two heat absorbers in a compounding way, and the heat generated in the polishing process can be effectively absorbed by the design because the polishing process of metal is a continuous heat release process, so that a polished workpiece is always kept at a proper temperature, and on the other hand, the polishing scraps generated in the polishing process can be taken away along with the melting and falling of the heat absorber.
(2) According to the polishing agent disclosed by the invention, the lubricant is added in the formula for the first time, and the selected lubricant has excellent lubricity and thermal conductivity, so that the polishing efficiency can be effectively improved.
(3) The thixotropic agent added in the super-coating can effectively change the appearance of the coating to generate regular grains, and the grains can effectively solve the problem that abrasive dust blocks the sand surface in the polishing process.
(4) The types and the adding proportion of the binder screened in the invention ensure that the coating can be synchronously lost in the grinding process, so that the coating always maintains excellent anti-blocking and heat-dissipating effects in the whole grinding process.
