Manufacturing method for preparing UV damp-proof sealing paint by utilizing UV sanding dust

Abstract

The invention provides a manufacturing method for preparing UV damp-proof sealing paint by utilizing UV sanding dust. UV paint and polished chemical hazardous waste dust generated in the existing woodproduct paint coating process are recycled; existing UV hazardous waste dust is classified and filtered, prepared dissolving and synthesizing base materials are added, and according to the process sequence, proportion and reaction time (20-30 min), the UV damp-proof sealing paint is prepared after stirring, reacting and filtering are conducted through a reaction kettle. The whole preparation process is pollution-free, simple, easy to operate and suitable for batch production; the prepared UV moisture-proof sealing paint can be used for moisture-proof sealing treatment of the back and the endof a wooden product household product, the wooden product is protected, the service life of the wooden product is prolonged, meanwhile, the manufacturing cost of an enterprise is reduced, and emissionof chemical hazardous waste is reduced. The prepared UV moisture-proof sealing paint is applied to the existing process and equipment, the process does not need to be adjusted additionally, equipmentdoes not need to be added additionally, and the production and use requirements can be met.

Description

technical field [0001] The invention relates to the technical field of paint hazardous waste collection and recycling, in particular to a method for preparing UV moisture-proof sealing paint by using UV sanding dust and its application. Background technique [0002] UV paint is the English abbreviation of Ultraviolet Curing Paint, that is, ultraviolet light curing paint, also known as photoinitiated coating, light curing coating. UV sanding dust refers to the chemical hazardous waste dust of UV sanding and grinding produced in the paint coating process of existing wood products. At present, the sanding dust generated by sanding and grinding of paint film in the paint production process in the wood product industry is a chemical hazardous waste (such as: PE paint, NC paint, PU paint or UV paint), all of which are dust-collecting bag filters. After collection, pack them into bags, pay a certain fee for the disposal of hazardous paint (for example: the processing fee in Henan ...

Problems solved by technology

[0003] Generally, it is put into a closed container for landfill treatment. This is the simplest treatment method. It is only the transfer of hazardous waste. There is no real scientific and reasonable recycling of hazardous waste. At the same time, it is necessary to build a special landfill, which occupies a large area and has a certain risk of harm to the surrounding environment.

The other is to use centralized incineration of natural gas. This treatment method requires hazardous waste incineration qualifications and professional incinerators; during the incineration process, the incinerated gas needs to be filtered, activated carbon adsorption, photo-oxygen catalysis and other treatments to meet the standards and then discharged , the equipment and treatment costs are relatively high; there are professional institutions abroad for treatment, and only large paint manufacturers or large hazardous waste treatment institutions in China have such equipment and treatment qualifications
