Safe and environmentally-friendly plastic-blasting method capable of realizing corrosion prevention and weather resistance of sheet material

Abstract

The invention discloses a safe and environmentally-friendly plastic-blasting method capable of realizing corrosion prevention and weather resistance of a sheet material. The safe and environmentally-friendly plastic-blasting method for corrosion prevention and weather resistance of the sheet material comprises the following steps: processing treatment of the sheet material: subjecting the sheet material to rough processing, and remaining a processing allowance of 3.5 to 5 mm so as to obtain a roughly-processed to-be-blanked material, then polishing the roughly-processed to-be-blanked material,and cutting a polished sheet material into a same shape so as to obtain a roughly-processed sheet material; and degreasing treatment of the roughly-processed sheet material: completely immersing theroughly-processed sheet material into a glycerin solution, carrying out soaking for 6 to 8 h, then stewing the soaked sheet material, carrying out slow heating until the temperature of glycerin is 50to 65 DEG C, carrying out heat-preserving and stewing for 4 to 6 h, taking the stewed sheet material out of the glycerin solution, and carrying out standing for 2 to 3 h so as to obtain a degreased sheet material. The safe and environmentally-friendly plastic-blasting method capable of realizing corrosion prevention and weather resistance of the sheet material provided by the invention has the following advantages: through the steps of degreasing treatment, treatment with flowing water, cyclic drying treatment, corrosion prevention treatment and the like, the sheet material is insusceptible togenerating the phenomenons of surface cracking and fracturing of the interior of the sheet material when in use, has the effects of corrosion prevention and aging resistance in long-term use at the same time, and has good application prospect.

Description

technical field [0001] The invention belongs to the technical field of plastic spraying for plates, and in particular relates to a safe and environment-friendly plastic spraying method for realizing anticorrosion and weather resistance of plates. Background technique [0002] Plastic spraying refers to the use of electrostatic generators to charge plastic powder. It is a surface treatment method for spraying plastic powder on parts.

[0002] Plastic spraying refers to the use of electrostatic generators to charge plastic powder. It is a surface treatment method for spraying plastic powder on parts. Plastic spraying is what we often call electrostatic powder spraying. Its treatment process was in the 1980s Since then, a relatively common metal surface treatment decoration technology has been adopted in the world. Compared with ordinary spray paint surface treatment, this technology has advantages in advanced technology, energy saving and high efficiency, safety and reliability, and bright color; while the existing plate spray method , Some panels have anti-corrosion and weather-resistant functions but do not have safety and environmental protection effects. Some panels have good anti-corrosion and safety and environmental protection effects, but the weather-resistant effect is not ideal, making the panels prone to deformation, and some panels have unsatisfactory anti-corrosion effects. , so that the board will crack during use. Therefore, we propose a safe and environmentally friendly spray method to achieve anti-corrosion and weather resistance of the board.
