A kind of low voc all solid cavity anticorrosion wax composition

Abstract

The invention relates to a low-VOC (volatile organic compound) full-solid-ingredient cavity anti-corrosion wax composition, which is prepared from the following ingredients in percentage by mass: 5 to 20 percent of wax materials, 5 to 20 percent of plant grease, 1 to 10 percent of oil-soluble anti-rust additives, 5 to 10 percent of anti-rust pigments, 1 to 5 percent of drying control agents, 0.1 to 1 percent of driers, 0.1 to 1 percent of silane coupling agents and 40 to 70 percent of basic oil. The anti-corrosion wax composition provided by the invention does not contain solvent ingredients; the ingredients are all solid ingredients; the low-VOC and environment-friendly effects are achieved; the flash point is high; the operation is safe; the low-VOC full-solid-ingredient cavity anti-corrosion wax composition can be used as anti-corrosion wax to be applied to coating of underpans, vehicle frames, hinges, vehicle door insides, window beam insides or other steel plate structures and components in automobile industry.

Description

technical field [0001] The invention relates to the field of metal anti-corrosion, in particular to an all-solid cavity anti-corrosion wax composition. The water-based anti-corrosion wax composition of the invention is used in the automotive industry for chassis, vehicle frames, hinges, car door interiors, and window beams Coating of interior or other steel sheet structures and components. technical background [0002] In today's society, with the continuous popularization of automobiles, domestic automobile production is also rising, the number of automobiles in the market is gradually increasing, and more and more problems are exposed. Metal corrosion is one of the most serious problems. one. The workpieces in the non-painted parts of the car will face the risk of corrosion, especially in the door cavity, hinge, chassis and other positions of the car. The existing anti-corrosion measures for the cavity mainly include hot-melt wax injection and anti-corrosion wax spraying....

AI Technical Summary

Problems solved by technology

[0004] For automobile volatile organic compound (VOC) pollution, Europe, the United States, Japan, Russia and other countries have implemented mandatory management systems according to relevant standards, while my country has no mandatory standards and management measures

On March 1, 2012, GB / T "Guidelines for Air Quality Evaluation in Passenger Cars" has been implemented for one year. Although it is a recommended standard, it also lays the foundation for the introduction of mandatory VOC emission standards in China. It can be seen that low The era of VOC products will not be far away

However, this form is not suitable for the long-term high anti-corrosion automobile inner cavity. The position of the weld seam with accumulated water is easy to cause reverse emulsification, and the film is easy to be washed away, which cannot achieve a long-term anti-corrosion period.

At the same time, water-based anti-corrosion wax products will freeze irreversibly in winter, and then break the emulsion and cannot be used

Under low temperature environment, the volatilization speed of water-based products is extremely slow, and it is not easy to form a film
