Abstract
The invention relates to a method for preparing sealants, in particular to a method for preparing a sealant for transmission equipment, and aims to solve the technical problems that the conventional anti-theft measures of the transmission equipment require aerial work and have poor safety performance and high labor intensity of workers. The method for preparing the sealant for the transmission equipment comprises the following steps of: 1) firstly, adding polyisocyanate, dithiocar-bamate, N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylene diamine, a reinforcing agent and solid phenolic resin into an open mill for uniform mixing, and adding the dithiocar-bamate and solid phenolic resin to prepare a film; 2) mixing the film and butanone, dissolving to prepare a liquid film, and uniformly mixing the liquid film, methanol, butanone and ethyl acetate to prepare glue solution; and 3) stirring and mixing the glue solution and liquid phenolic resin so as to prepare the sealant. The sealant has the advantages of strong cohesive force, high safety performance, simple using method, short operation time, and the like.
Description
Technical field
The present invention relates to a kind of preparation method of seal gum, be specifically related to a kind of preparation method of sealant for transmission equipment.
Background technology
The electric power and the people's production, the life closely bound up, for people's lives provide many convenience, for society has created enormous wealth.Yet in recent years, because nonferrous metal price skyrockets, it is very serious that the lawless person steals the electric power facility situation, and the sign that worsens is year by year arranged, and electric power facility stolen brought huge direct economic loss to power supply enterprise on the one hand; On the other hand, steal and brought very important hidden danger for the safe operation of distribution network, increased the operating pressure of the unit of maintenance of basic unit, caused ill effect to society.Therefore the theftproof performance of strengthening electric power facility itself is most important.
Present stage, the anti-theft measure of transmission facility generally adopted two kinds of anti-theft bolt and the spot welding of tower material, and anti-theft bolt needs working aloft, and the settling time is long very dangerous; The spot welding of tower material has only below 6 meters and just can use, and spot welding point also is easy to lose its theftproof performance because of getting rusty, and need regularly keep in repair, and labor strength is big.
Summary of the invention
Technical problems such as the objective of the invention is needs working aloft at the anti-theft measure of current power transmission equipment, and poor safety performance, labor strength are big provide a kind of preparation method of sealant for transmission equipment.
The preparation method of a kind of sealant for transmission equipment of the present invention may further comprise the steps:
1) material of getting following parts by weight adds mill: polymeric polyisocyanate 50～150, dithiocar-bamate 0.5～1.5, N-(1, the 3-dimethylbutyl)-N '-diphenyl-para-phenylene diamine 0.5～1.5, strengthening agent 40～80 and solid phenolic resin 25～75, under 40～60 ℃ of roller temperature, mix, and then the solid phenolic resin that adds 0.5～1.5 part of dithiocar-bamate and 75～225 parts is made film;
2) film is mixed according to 1: 4～6 weight ratio with butanone, dissolved under the room temperature 20～30 hours, make liquid glue, then according to 1: 0.3: 1.3: 3 volume ratio mixes liquid glue, methyl alcohol, butanone and ethyl acetate, makes glue;
3) mixed 0.4～0.6 hour according to 1: 2～3 volume ratio glue and liquid phenolic resin again, make seal gum step (2).
Wherein said strengthening agent is carbon black or white carbon black.
The using method of seal gum of the present invention:
The cleanings such as grease, iron rust, dirt of parts surface of will boning earlier are clean, after the drying seal gum of the present invention is applied in the bonding parts surface, use then wetting spatula with adhesive of the present invention on seam edge, equating gets final product, if temperature is lower than 5 ℃ when using, this tackiness agent must be left under 20 ℃ of temperature in advance.
Compared with prior art, the present invention has following beneficial effect:
1) seal gum of the inventive method preparation is main sizing with raw material synthetic polyether polyols with reduced unsaturation, being equipped with anti-aging agent, stiffening agent, toughner, solvent etc. carries out reasonably combined, especially the adding of liquid phenolic resin, further increased the surface adhesion force between the transmission line part, and volatilization along with solvent, cohesive force strengthens, and the adding of rational proportion anti-aging agent and toughner further improved the resistance to deterioration and the toughness of sizing, and life-time service is effective in the open air;
2) the inventive method adhesive effect of preparing seal gum mainly exists the principle of consistency to realize by means of the physico-chemical property between sizing and the transmission facility metal parts, the safety performance height, and seal gum has anti-corrosion function to metal parts, guarantees that the mechanical property and the physicals of transmission of electricity parts is constant;
3) preparation method of the present invention is simple, cost is low, and the seal gum using method for preparing is simple, the operating time short, not limited by the high-altitude, and use range is wide;
Bonding strength, shearing resistance performance and weather resistance to tackiness agent of the present invention are tested, and the results are shown in following table, and the bonding effect of visible tackiness agent of the present invention satisfies the bonding requirement of transmission line part.
