Abstract
The invention relates to the technical field of quickly curing powder coating, in particular to a pure epoxy quickly-cured powder coating and a production method thereof. The powder coating contains the following compounds according to percentages by weight: 52-57wt% of epoxy, 2-3wt% of curing agent, 0.1-1wt% of curing catalyst, 0.1-0.4wt% of benzoin, 0.7-1.4wt% of inlet flatting agent, 0.4-1.0wt% of castor oil, 5-10wt% of pigment, 0.3-1.2wt% of antioxidant and 28-35wt% of blanc fixe. Due to special curing catalyst and curing agent, the coating has high curing speed, and the impact resistance of the coating is guaranteed simultaneously.
Description
Technical field
The present invention relates to be used for expediting setting type powder coating technical field, especially a kind of pure epoxy expediting setting type powder coating and preparation method thereof.
Background technology
Powder coating with the high-performance of its environmental protection, economy, is widely used in the external coating of various metalworks.Along with the environmental protection characteristic of powder coating, Application Areas has obtained expansion in recent years; Simultaneously, the condition of cure to powder coating also requires more and more higher.
The condition of cure of general powder coating is that storing temperature is higher mostly, and storing time is longer, and this has just caused the waste of the energy.Therefore, consider expediting setting type powder coating broad market prospect from the angle of saving the energy, reducing cost and enhancing productivity.
Summary of the invention
In order to overcome long shortcoming of existing powder coating solidification time, the invention provides a kind of pure epoxy expediting setting type powder coating and preparation method thereof.
The technical solution adopted for the present invention to solve the technical problems is: a kind of pure epoxy expediting setting type powder coating, the component of this powder coating and the weight percent of content are as follows: Resins, epoxy 52%～57%, solidifying agent 2%～3%, curing catalyst 0.1%～1%, st-yrax 0.1%～0.4%, import flow agent 0.7%～1.4%, Viscotrol C 0.4%～1.0%, colorant 5%～10%, oxidation inhibitor 0.3%～1.2% and process white 28%～35%.
According to another embodiment of the invention, comprise that further described Resins, epoxy is bisphenol A type epoxy resin E-12.
A kind of preparation method of pure epoxy expediting setting type powder coating, this method comprises the steps:
A, Resins, epoxy 52%～57%, solidifying agent 2%～3%, curing catalyst 0.1%～1%, st-yrax 0.1%～0.4%, import flow agent 0.7%～1.4%, Viscotrol C 0.4%～1.0%, colorant 5%～10%, oxidation inhibitor 0.3%～1.2%, process white 28%～35% are put into container by proportioning carry out batch mixing, mix;
B, get among the step a the material that mixes through extruding-compressing tablet-pulverizing after, promptly make finished product.
The invention has the beneficial effects as follows,, make that the curing of coating process is very fast, guaranteed the impact resistance of filming simultaneously owing to adopt special curing catalyst and solidifying agent among the present invention.
