CN105257211A - Synergistic positive displacement motor - Google Patents

Abstract

The invention discloses a synergistic positive displacement motor. The synergistic positive displacement motor comprises a drill body which is coated with a protective layer. The protective layer is prepared according to the first step of taking 9.6 parts of methyl polyester resin with activity, 0.9 part of propylene glycol, 0.9 part of sodium hydroxyethyl sulfonate, 1.3 parts of acrylic acid, 0.7 part of dimethicone and 1.2 parts of maleic anhydride modified polyethylene, and fully and evenly stirring the materials to obtain bottom layer protection paint, the second step of taking 5.7 parts of silica sol, 2.3 parts of tetraethylammonium tetrafluoroborate, 1.2 parts of trisodium phosphate, 0.7 part of mahogany petroleum sulfonate, 3.6 parts of polyamide resin and 1.1 parts of dimethylethanolamine, and fully and evenly stirring the materials to obtain surface layer protection paint, the third step of spraying the bottom layer protection paint on the surface of the drill body for curing and drying, and the fourth step of spraying the surface layer protection paint on the surface of the drill body for curing and drying. According to the synergistic positive displacement motor, the drill body is coated with the protective layer, so the service life of the synergistic positive displacement motor can be prolonged.

Description

Screwdrill of synergic action

Technical field

The present invention relates to Screwdrill of synergic action.

Background technology

Existing Screwdrill of synergic action, its working environment is general relatively more severe, and asks work when needing long, himself needs to be effectively protected.

Summary of the invention

The object of the present invention is to provide a kind of Screwdrill of synergic action, its tool body is coated with topping, makes tool body have wear-resisting, corrosion resistant and heat insulation performance, can improve the application life of Screwdrill of synergic action.

For achieving the above object, technical scheme of the present invention is a kind of Screwdrill of synergic action of design, and comprise tool body, described tool body is coated with topping, and described topping obtains as follows:

1) get 9.6 parts of band active methyl mylar, 0.9 part of propane diols, 0.9 part of sodium isethionate, 1.3 parts of acrylic acid, 0.7 part of dimethicone, 1.2 parts of maleic anhydride modified polyethylene stir, and obtain protective underlayer coating;

2) get 5.7 parts of Ludox, 2.3 parts of tetrafluoro boric acid triethylammonium tetrakis, 1.2 parts of tertiary sodium phosphates, 0.7 part of petroleum sulfonate, 3.6 parts of polyamides, 1.1 parts of dimethylethanolamines stir, and obtain surface layer protective coating;

3) at the first sprayed layer undercoat protective coating in tool body surface, solidification is dry;

4) spraying surface protective coating again, solidification is dry.

Advantage of the present invention and beneficial effect are: provide a kind of Screwdrill of synergic action, and its tool body Tu is covered with topping, make tool body have wear-resisting, corrosion resistant and heat insulation performance, can improve the application life of Screwdrill of synergic action.

Detailed description of the invention

Below in conjunction with embodiment, the specific embodiment of the present invention is further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.

The technical scheme that the present invention specifically implements is:

A kind of Screwdrill of synergic action, comprise tool body, described tool body is coated with topping, and described topping obtains as follows:

1) get 9.6 parts of band active methyl mylar, 0.9 part of propane diols, 0.9 part of sodium isethionate, 1.3 parts of acrylic acid, 0.7 part of dimethicone, 1.2 parts of maleic anhydride modified polyethylene stir, and obtain protective underlayer coating;

2) get 5.7 parts of Ludox, 2.3 parts of tetrafluoro boric acid triethylammonium tetrakis, 1.2 parts of tertiary sodium phosphates, 0.7 part of petroleum sulfonate, 3.6 parts of polyamides, 1.1 parts of dimethylethanolamines stir, and obtain surface layer protective coating;

3) at the first sprayed layer undercoat protective coating in tool body surface, solidification is dry;

4) spraying surface protective coating again, solidification is dry.

The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
