Abstract
The invention discloses a water-resistant insulating varnish, and relates to the technical field of paints. The water-resistant insulating varnish comprises the following components in parts by weight: 100-150 parts of high molecular weight epoxy resin, 1-2 parts of an initiator, 10-20 parts of an activated diluent, 4-6 parts of a flexibilizer, 4-6 parts of an antistatic agent, 30-50 parts of pigment and 50-80 parts of water. The water-resistant insulating varnish disclosed by the invention is free of an organic solvent, free of pollution, good in insulating property and good in water resistance, and has the advantages of high film hardness, good plumpness, high adhesion, excellent three-proofing properties and good mechanical property, is dried at low temperature, and can be widely applied to an insulating varnish of an electric appliance.
Description
Technical field
The present invention relates to technical field of coatings, especially a kind of water-fast insullac.
Background technology
Insulation, is used exactly nonconducting material by electrified body isolation or wraps up, with a kind of security measures that electric shock is shielded.Along with scientific and technological development, the raising of people's living standard, electric product has spread to all trades and professions, but the insulating requirements of its product is very high, although existing surface insulation description of materials is a lot of on market, Performance Ratio is more single, its purposes specific aim is very strong, but can't accomplish protection against the tide, anticorrosion, high temperature resistant, insulation requirement, the insulation level of insulating material is inadequate, is limiting the development of electrical equipment, electromechanics trade.Insullac arises at the historic moment under such needs.Insullac is mainly used in flooding coil and the insulation component of motor, electrical equipment, fill its space and micropore, dry or heating, drying after, make immersed thing epiphysis form a closely knit integral body, thereby improve its disruptive strength, mechanical property and moisture resistance, heat-resisting, heat conduction and the performance such as anti-oxidant.
At present, most insullac is all solvent-borne type, contains a large amount of volatile organic compoundss, poisonous and inflammable, and environment and human body are worked the mischief.
Summary of the invention
It is water-based and the water-fast insullac that meets environmental requirement that technical problem to be solved by this invention is to provide a kind of product forms.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
It comprises the constituent of following weight part:
100 parts-150 parts of high molecular expoxy resins, 1 part-2 parts of initiators, 10 parts-20 parts of reactive thinners, 4 parts-6 parts of toughner, 4 parts-6 parts of anti-static agents, 4 parts-6 parts of pigment, water 30-40 part.
In technique scheme, scheme can also be more specifically: the high molecular expoxy resin that described high molecular expoxy resin is modification; Described initiator is peroxide diisopropylbenzene(DIPB), and described reactive thinner is one or both the mixture in vinylbenzene or pentaerythritol triacrylate; Described toughner is nano-calcium carbonate or nano titanium oxide; Described anti-static agent is a kind of in fatty alcohol-polyoxyethylene ether or Varion CDG-K, and described water is deionized water.
Further: the weight part of constituent is:
100 parts of high molecular expoxy resins, 1 part of initiator, 20 parts of reactive thinners, 4 parts of toughner, 6 parts of anti-static agents, 50 parts of pigment, 50 parts, water.
Further: the weight part of constituent is:
150 parts of high molecular expoxy resins, 2 parts of initiators, 10 parts of reactive thinners, 6 parts of toughner, 4 parts of anti-static agents, 30 parts of pigment, 80 parts, water.
Owing to adopting technique scheme, the beneficial effect that the present invention has is:
This water-fast insullac organic solvent-free, pollution-free, there is good insulation preformance, hardness of paint film is high, fullness ratio is good, oven drying at low temperature, high adhesive force, good NBC protective performance, good mechanical property.
