Abstract

The invention discloses a steel wire rope coating, which is composed of the following formula in percentage by weight: 25-85% of pitch, 10-50% of cement, and 5-25% of steel wire rope surface grease. The steel wire rope coating is coated on a steel wire rope, and the steel wire rope coating has better waterproofness and corrosion resistance, thereby preventing sea water from corroding the steel wire and entering the inside of the steel wire rope, and further prolonging the life of the steel wire rope.

Description

A kind of wireline coating

Technical field

The present invention relates to a kind of coating, relate in particular to a kind of coating that is used to be coated on the wireline.

Background technology

There are 3.2 ten thousand kilometers shorelines in China, and wherein mainland coastline is 1.8 ten thousand kilometers, and the Dandong is arrived from the east, Port of Fangcheng in Guangxi in 1.4 ten thousand kilometers in shoreline, island, and fishing resources are very abundant.Arrange first of the world fishery big country; The development of fishery in recent years is comparatively rapid, along with the macro adjustments and controls of country to fishing resources, disorderly catches random dragging for and has obtained effective control; The fishery industry begins to have driven the development of related industries thus to long range fishing, the development of deep sea fishing aspect.Through Guangxi, Guangdong, Fujian, Jiangsu, Shandong, Liaoning etc. being economized the examination of fishery wireline market; All have nearly thousand fishing boats to stop harbours and harbour to the fishing port; Ground such as Shantou City, Guangdong Huilai county Castalia town, the auspicious sesame in Shishi City, Fujian Province town, Shenzhen and Shanghai, Jinjiang City town, Dongshan Town, Zhangzhou City, Wu Yudao village only; Have surplus all kinds of fishing boats of ocean and deep sea fishing nearly 30,000; Surplus wherein trawling (comprise high-power singly drag, two dragging) can reach 3000, fishery wireline yearly consumption is about 4000～5000 tons.Estimate national fishery wireline consumption more than 80,000 tons, at present, the more thick zinc-plated fishery wireline that is still is used in each fishing port; Because the singularity of fishery wireline environment for use, industry are always with the grease coating of zinc coating thickness (going up the zinc amount) and the wireline main goal of attack as technology, to expect that wireline has corrosion resistance preferably; Since after the last zinc amount of steel wire reaches certain limit, want to improve once more the last zinc amount of steel wire, comparatively difficult; Surperficial grease on the wireline, along with the prolongation of duration of service always in the volatilization of becoming estranged that continues to flow, in the fish production; Particularly singly drag, pair trawling; Wireline can not accomplish to replenish grease basically after special processing, therefore above-mentioned many reasons cause the work-ing life of wireline shorter.

Analyze from numerous fishery wireline damage types; Wherein the sea-water corrosion steel wire is inner with the entering wireline; Cause the early stage sizable ratio that accounted for of damaging of wireline; Wireline integral body is often broken brings the financial loss that can't retrieve to the fisherman, and the deep-sea two boat trawler, pair is once fished for financial loss on average about 70,000 yuan.

Summary of the invention

A technical problem to be solved by this invention is: all wireline coatings preferably of a kind of water-repellancy and erosion resistance are provided.

For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of wireline coating, and the weight percent prescription of said coating consists of: pitch: 25%～85%, cement: 10%～50%, wire rope surface grease: 5%～25%.

As a kind of optimized technical scheme, the dropping point of said wire rope surface grease is 50～70 ℃, and kinematic viscosity is no less than 70 (m^2)/s.

As a kind of optimized technical scheme, said pitch is 70～No. 100 pitches, and said cement is 225～No. 525 cement.

Beneficial effect of the present invention: the wireline coating among the present invention is applied on the wireline; Because the wireline coating among the present invention has better waterproof and erosion resistance; Thereby can prevent the sea-water corrosion steel wire and get into wireline inside, and then the life-span of having improved wireline.In addition through to the dropping point of pitch model, cement model, wire rope surface grease and the selection of kinematic viscosity, can make that the wireline coating high-temp 40 degree left and right sides are tack-free, not chap about subzero 30 degree of low temperature.

Embodiment

Embodiment 1:

A kind of wireline coating, the weight percent prescription of said coating consists of: pitch: 25%, cement: 50%, wire rope surface grease: 25%.The dropping point of said wire rope surface grease is 50～70 ℃, and kinematic viscosity is no less than 70 (m^2)/s.Said pitch is 70～No. 100 pitches, and said cement is 225～No. 525 cement.

Embodiment 2:

A kind of wireline coating, the weight percent prescription of said coating consists of: pitch: 85%, cement: 10%, wire rope surface grease: 5%.The dropping point of said wire rope surface grease is 50～70 ℃, and kinematic viscosity is no less than 70 (m^2)/s.Said pitch is 70～No. 100 pitches, and said cement is 225～No. 525 cement.

Embodiment 3:

A kind of wireline coating, the weight percent prescription of said coating consists of: pitch: 40%, cement: 40%, wire rope surface grease: 20%.The dropping point of said wire rope surface grease is 50～70 ℃, and kinematic viscosity is no less than 70 (m^2)/s.Said pitch is 70～No. 100 pitches, and said cement is 225～No. 525 cement.

The working method of wireline coating is among the present invention: select 70～No. 100 pitch, pitch is heated to 60-90 ℃, pitch is melted state; Then add dropping point and be 50～70 ℃, kinematic viscosity and be no less than the wire rope surface grease of 70 (m^2)/s; Add cement after stirring again 225～No. 525, continue to stir, wherein; The shared mass percent of pitch is 25%～85%; The shared mass percent of wire rope surface grease is 5%～25%, and the shared mass percent of cement is 10%～50%, can obtain the wireline coating among the present invention like this.

Wireline coating among the present invention is applied on the wireline,, thereby can prevents the sea-water corrosion steel wire and get into wireline inside because the wireline coating among the present invention has better waterproof and erosion resistance, and then the life-span of having improved wireline.In addition, bonding force is also better between the coating, difficult drop-off.Through selecting pitch is 70～No. 100 pitches, and cement is 225～No. 525 cement, and the dropping point of wire rope surface grease is 50～70 ℃, and kinematic viscosity is no less than 70 (m^2)/s.The wireline coating high-temp 40 degree left and right sides are tack-free, low temperature subzero 30 does not chap about spending thereby can make.

What should explain at last is: the above is merely the preferred embodiments of the present invention; Be not limited to the present invention; Although the present invention has been carried out detailed explanation with reference to previous embodiment; For a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
