Description
Technical field
The invention belongs to industrial coating technical field, it is specifically related to a kind of water-soluble insulating varnish and its preparation method.
Background technology
Insullac is mainly used in coil and other insulation component of electrical equipment and electrical, fills its space, makes immersed thing become a closely knit entirety, thus improve its insulating property, mechanical property and weather resistance after solidification. Insullac is generally divided into non-solvent paint and solvent-free paint two kinds. Non-solvent paint is as solvent by organic compound; What solvent-free paint adopted is reactive thinner, and thinner participates in film forming. Although solvent-free paint can reduce the volatilization of organic solvent to the pollution of environment, but the reactive thinner in solvent-free paint also has certain volatility, equally human and environment is caused harm, and inflammable and explosive, there is potential safety hazard in transport storage.
At present, insulative water paint obtains application in industries such as power tool, water pump, gardens motor, small generator, barretter, miniature transformers. Insulative water paint, as a kind of environment-friendly type coating, becomes the direction of sector application development with its low stain, energy-saving safe, the characteristic such as easy to use.
Mostly there is following shortcoming in current insulation technology: 1, oiliness insullac need to use a large amount of solvent cut when varnished insulation is constructed, generally only has nearly about 15% solid part, thus 85% in oiliness insullac is partly for VOCS has been discharged in air, and air is dirty serious; 2, because having the volatilization of a large amount of solvent and by the Cutaneous permeation to operator in operating process, and seriously affect HUMAN HEALTH, 3, volatility because of solvent is big, for making insullac construction liquid keep preferably low viscosity, and the construction process insulated that arrives needs constantly supplement new solvent and causes cost extremely high, use into quite high, without any cost advantage; 4, oiliness insullac belongs to combustible and explosive articles, and its production, storage, transport and construction process all exist bigger potential safety hazard; 5, solvent is in volatilization and insullac film forming solidification process, very easily absorbs moisture in air and causes insulating property to be greatly affected;6, simultaneously for dead front type motor, very easily medium oil insullac produces gas reaction to the bearing of motor with stator, and shortens motor work-ing life.
Summary of the invention
For solve volatile matter that existing insullac exists mainly with and the problem of insulating property difference; the present invention proposes a kind of water-soluble insulating varnish; decrease the VOCS discharge of at least 80% to greatest extent and protection of the environment is not contaminated; human body is affected without Major health; while safety and environmental protection, pole significantly reduces use cost at least 40%, has extremely high social value and the new insulation material of economic worth.
