Abstract
The invention discloses a one-component room temperature self-drying color organosilicon heat-resistant coating and a preparation method thereof. The coating is composed of the following components by weight: 10-20 parts of acrylic resin, 25-35 parts of silicone resin, 1-20 parts of a pigment, 10-20 parts of a filler, 0.5-1.0 part of a thixotropic agent and 5-20 parts of a solvent. The preparation method is as below: adding acrylic resin, silicone resin and the solvent into a reaction kettle, heating to 40-50 DEG C, stirring evenly, then adding the pigment and filler, grinding to less than 20 microns, finally adding the thixotropic agent, stirring at high speed uniformly, and discharging. The coating dries naturally at normal temperature, has heat resistance temperature reaching 250 DEG C and can be prepared into a plurality of colors. For usage, the coating is directly diluted and is ready for construction immediately; the coating has excellent application property and film drying property, and can be used in the field of heat resistant coatings with heat resistant, and decoration and warning requirements, such as metallurgical equipment and motor shell.
Description
Technical field
The present invention relates to paint field, particularly a kind of single-component normal temperature self-drying coloured organosilicone heat resisting coating and preparation method.
Background technology
At present, some large-scale high temperature services are often comprised in industrial production, large-scale crucible, iron-smelting furnace, smelting furnace etc. in such as metallurgy industry, these equipment lead to common steel to be made, in the process of life-time service, steel are easily subject to the corrosion of damp atmosphere, very easily there is stress corrosion crack in the steel surface after corrosion, brings very large hidden danger to production safety.
In prior art, usually need emanation spraying paint on these high temperature services, to play etch-proof effect, thus the normal operation of the equipment of guarantee.But existing coating resistance toheat is not good enough, is easily subject to high temperature and comes off after spraying, in addition, because these high temperature services exist certain danger, but the color of coating is single, can not play warning function, easily produce potential safety hazard after spraying to technician.
Therefore, how providing a kind of colored heat resisting coating, level can have non-corrosibility and thermotolerance, have again abundant color, to meet the protection against corrosion demand of high temperature service in industrial production, is the required technical problems solved of those skilled in the art.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of single-component normal temperature self-drying coloured organosilicone heat resisting coating and preparation method.This coating can normal temperature self-drying, and heat resisting temperature reaches 250 DEG C, can be made into multiple color.Can construct after directly diluting in use, there is excellent coating application and dried coating film, be applicable to the existing heat resistant requirements such as metallurgical equipment, motor housing, have again heat resisting coating field that is ornamental and warning requirement.
A kind of single-component normal temperature self-drying coloured organosilicone heat resisting coating provided by the invention, composed of the following components by mass parts: acrylic resin 10-20 part, silicone resin 25-35 part, tinting pigment 1-20 part, filler 10-20 part, thixotropic agents 0.5-1.0 part, solvent 5-20 part.
