Problems solved by technology

Often the equipment has not been shipped from the factory, but it has been placed in the open air of the factory for a year and a half, and the protective layer of the bundled cables has been seriously aged and yellowed. The low-molecular-weight plasticizers of dibutyl phthalate will continue to migrate to the surface, causing the cable coating to lose its flexibility and appear (in winter) hard, brittle, cracked, and (in summer) sticky, etc. It cannot meet the actual use requirements, which not only causes a huge waste of resources for the enterprise, but also seriously affects the delivery date of the equipment

Embodiment 1

[0021] A kind of sealing paint for sheathing layer of bundled cables is prepared from the following material raw materials in percentage by weight:

[0022]

[0023] Polyacrylic resin and hexamethylene diisocyanate in the above-mentioned formula are coating resin base material, and syloid ED-5 (matting agent), modaflow 9200 (leveling agent), TD-01 (dispersing agent) are auxiliary agents for coating, and butyl acetate is Mixture of solvents for paints.

[0024] The preparation method of this bundled cable covering layer sealing coating is:

[0025] (1), add the resin base material of formula quantity 50%, the mixed solvent of formula quantity 30% and the auxiliary agent of formula quantity into the container and stir evenly;

[0026] (2) Add pigments and fillers according to the amount, and stir while adding materials. After there is no visible dry powder, use a high-speed disperser at 2000 rpm or above for pre-dispersion treatment;

[0027] (3), grind the above-mentioned ...

Abstract

The invention relates to a sealing coating for cluster cable coating layer protection of large machinery. The sealing coating comprises a resin base, a pigment, a filler aid, and a mixed solvent, wherein the resin base comprises a polyacrylic resin and an aliphatic curing agent, or comprises a polyester resin and an aliphatic curing agent, the filler aid comprises a delustering agent, a leveling agent and a dispersing agent, and the mixed solvent comprises n-butyl acetate and / or acetic ether and / or xylene and / or cyclohexanone and / or butanone and / or ethylene glycol ethyl ether acetate. According to the invention, the formula is reasonable, the construction is simple and convenient, and a construction cost is low; the sealing coating disclosed herein has extremely good adhesion to the cable surface; by rebuilding the whole cluster cable or carrying out strengthening treatment on a new cable in advance, the coated cable has extremely good outdoor durability, is difficult of yellowing, and can be used in acid, alkali, salt, sandstorm, asphalt gas and other various harsh environments, thus the application effect of the cluster cable is improved obviously, and the manufacture and use costs of various outdoor machinery are reduced. The sealing coating disclosed herein is good for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of chemical coating agents, and relates to a sealing coating used for protecting the covering layer of large mechanical bundled cables. Background technique [0002] At present, among all kinds of mechanical equipment used outdoors, especially large-scale mechanical equipment such as road construction machines and paver machines, due to the limitation of materials used, the outdoor durability (service life) of bundled cables is far inferior to that of mechanical coatings. durable. Often the equipment has not been shipped from the factory, but it has been placed in the open air of the factory for a year or a half, and the protective layer of the bundled cables has been seriously aged and yellowed. The low-molecular-weight plasticizers of dibutyl phthalate will continue to migrate to the surface, causing the cable coating to lose its flexibility and appear (in winter) hard, brittle, cracked, and (in summer) s...
