Abstract
The invention discloses a priming paint for a color galvanized steel plate. The priming paint comprises the following components in percentage by weight: 30-50% of saturated carboxylic acid polyester, 15-40% of filler, 1-2% of a siloxane coupling agent, 0.5-1% of phthalate ester, 1.5-3% of a pre-dispersed pigment preparation and 4-52% of a dimethyl benzene solvent. According to the priming paint disclosed by the invention, the saturated carboxylic acid polyester is adopted as a base of the priming paint, the pre-dispersed pigment preparation can be quickly dispersed and dissolved in the base, and meanwhile other auxiliary agents are added to prepare the priming paint. In actual use, as the saturated carboxylic acid polyester has relatively excellent high temperature resistance and good color consistency, the priming paint containing the same has better properties, can be sprayed on metallic surfaces of iron materials, aluminum materials or stainless steel and the like, and can be widely applied to heat-resisting materials of baking trays, electric frying pans and barbecue sets.
Description
Technical field
The invention belongs to the field of coating of metallic substance, specifically, is a kind of color steel sheet primer base.
Background technology
Coating on metal not only can play protection and beautify the effect of metal appearance, as antirust and painted etc., sometimes, coating also can be utilized to realize some special functions, as improved lubrication, improving deep drawability etc.In actual application, effect and the coating of coating have close relationship.For heat resisting coating, heat resisting coating refers to that its film can maintain high temperature (being generally more than 150 DEG C) not cracking for a long time, yellowish appearance degree is little, do not come off, suitable physicals and protection function can also be kept, existing patent documentation CN1583912(coiled material priming paint coating and method for making thereof, 2005.02.23) disclose one by linear polyester resin or epoxy resin, aminoresin, rust-stabilising pigment, the professional coating of auxiliary agent and solvent composition, when reality uses, because the heat resisting temperature of vibrin or epoxy resin is at 130 ~ 155 DEG C, therefore, be applicable to heat zinc coating plate, electrolytic galvanized sheet, the best results such as alloying plate and cold rolled plate material.
Along with the progress of technology, it is found that silicone resin also has preferably thermotolerance, the basic framework of silicone resin is the main chain of Si-O, higher than the bond energy of the C-C key of common high molecular polymer, it is heat-resisting and antioxygenation is also stronger, under normal circumstances, the heat resisting temperature of silicone resin is 300 DEG C, be proven, silicone resin is except thermotolerance, also show excellent weathering resistance, pollution resistance, pull out water-based, the performance such as winter hardiness and resistance to chemical attack, but when reality uses, but also there are the following problems, such as: need hot setting (more than 250 DEG C) and set time long, not easily large-area construction, to the poor adhesive force of metal, poor solvent resistance and cost of manufacture high, for this reason, we certainly will need to find a kind of high performance material that can substitute silicone resin, simultaneously, more existing vibrin or epoxy resin is also needed to have higher thermotolerance.
Summary of the invention
