Problems solved by technology

The existing reuse method of hazardous waste HW13 class 900-451-13 waste epoxy resin powder is basically mixed with wood flour and other polymer materials and additives for granulation and regeneration. Buried for disposal, but the process of reusing other HW12 type 900-256-12 waste ink slag powder has not been reported, which may be the cost of the process of wet treatment of HW49 type 900-041-49 waste ink packaging It is also relatively high, because there is no effective way to obtain the 900-256-12 waste ink slag powder required for polymer molding

Embodiment 1

[0017] A kind of recycling method of HW13 waste epoxy resin and HW12 waste ink slag powder, comprises the following steps:

[0018] S1: Prepare materials, crush and grind the waste epoxy resin of HW13 category 900-451-13 produced by the crushing of waste circuit boards of HW49 category 900-045-49 to make waste epoxy resin powder for use, and grind the waste epoxy resin powder of HW49 category 900-041-49 The HW12 type 900-256-12 waste ink slag generated from the treatment of waste ink packaging containers is dried, crushed and ground, and then sieved with a 50-mesh screen to make waste ink slag powder for use; S2: Ingredients, add 35 Parts of waste epoxy resin powder, 15 parts of PVC-SC5, 10 parts of active light calcium, 7 parts of curing agent, 2 parts of toner, 2 parts of ACR additives and 2 parts of PE wax, through sorting The machine adds 10 parts of waste ink slag powder to the transfer hopper. The light dust in the waste ink slag powder is treated by the bag filter in th...

Embodiment 2

[0020] A kind of recycling method of HW13 waste epoxy resin and HW12 waste ink slag powder, comprises the following steps:

[0021] S1: prepare materials, the same as in Example 1; S2: batching, add 50 parts of waste epoxy resin powder, 21 parts of PVC-SC5, 15 parts of active light calcium, 8 parts of curing agent, 5 parts of Toner, 2 parts of ACR additives and 2 parts of PE wax, add 15 parts of waste ink slag powder to the transfer hopper through the sorting machine, and the light dust in the waste ink slag powder passes through the bag type dust removal in the sorting machine After being treated by the filter, it is added to the transfer hopper, and the dust in the waste ink slag powder is sent to the pulse dust collector through the sorter, and discharged after water spraying and plasma adsorption operations; S3: Stirring, after mixing the raw materials in the transfer hopper Transported to the low-speed mixer through the conveyor belt and stirred evenly; S4: Molding, feedi...

Abstract

The invention relates to the technical field of treatment and recycling of HW49 hazardous waste, in particular to a reutilizing method of HW13 waste epoxy resin and HW12 waste printing ink slag powder. The method comprises the steps of preparing, blending, stirring, forming, cutting and the like. The preliminarily treated H13 waste epoxy resin powder and HW waste printing ink slag powder are mixedin a proportion, then a proper amount of PVC-SC5, active light calcium carbonate, a curing agent, toner and PE wax are added, thermoplastic forming is carried out after stirring and mixing, a novel section material is prepared after cooling and cutting a formed product, advanced treatment on the hazardous waste including the HW13 waste resin and HW12 waste printing ink slag is achieved, the industrial chain is extended, the principle of treating waste with waste, and turning waste into wealth is carried forward, and besides, the generated novel section material is endowed with corrosion resistance and oxidation resistance of part of raw materials.

Description

technical field [0001] The invention relates to the technical field of HW49 hazardous waste treatment and reuse, in particular to a method for reusing HW13 waste epoxy resin and HW12 waste ink slag powder. Background technique [0002] The 2016 edition of the "National Hazardous Waste List" pointed out that the waste resin powder produced by HW13 category 900-451-13 comes from the waste circuit board crushing process of HW49 category 900-045-49, and the waste ink residue produced by HW12 category 900-256-12 The powder comes from the HW49-041-49 waste ink packaging container treatment process, both of which are difficult points in the current hazardous waste treatment. The existing reuse method of hazardous waste HW13 class 900-451-13 waste epoxy resin powder is basically mixed with wood flour and other polymer materials and additives for granulation and regeneration. Buried for disposal, but the process of reusing other HW12 type 900-256-12 waste ink slag powder has not bee...
