Embodiment 1

[0055] Environmentally friendly pencil board production formula, raw materials include the following ingredients, vinyl chloride resin, waste PVC, light stone powder, wood powder, fiber powder, foaming agent, foaming regulator, stearic acid, coupling agent, plasticizer , polyethylene wax, stabilizer. Vinyl chloride resin, referred to as PVC resin powder, is a collective name for vinyl chloride homopolymer and vinyl chloride copolymer. Waste polyvinyl chloride is waste PVC material. Light stone powder is light calcium carbonate. Wood powder is plant fiber, specifically the powder made from wood, which can be leftover scraps from wood processing in furniture factories, density board factories, and multi-layer board factories; fiber powder is raw materials containing chemical fibers. The foaming agent is an azodicarbonamide molecule: C2H4O2N4, which acts to adjust the density of the product, reduces the processing resistance in the production of pencils, and controls the specif...

Abstract

The invention relates to the field of pencil board production, and especially relates to a manufacturing formula of an environment-friendly pencil board and a technology thereof. The raw material comprises the following components: vinyl chloride resin, waste polyvinyl chloride, lightweight stone flour, wood powder, fiber powder, a foaming agent, a foaming conditioning agent, stearic acid, a coupling agent, a plasticizer, polyethylene wax, and a stabilizing agent. The manufacturing technology comprises the steps of grinding, milling, high-temperature material stirring, low-temperature material stirring, extruding, three-roller sizing, pulling, cutting, and packing. The technology recycles the waste generated during the pencil processing process, is beneficial to protect the natural ecological environment, saves a large amount of wood at the same time; furthermore, the technology saves a large amount of labor force by reducing the processing steps, and reduces the labor intensity for workers at the same time.

Description

technical field [0001] The invention relates to the production of pencil boards, in particular to the formula and process for making environmentally friendly pencil boards. Background technique [0002] The existing pencil board production can be used to process stationery and office supplies such as various pencils, paintbrushes and makeup brushes. Its material mainly uses wood as a raw material, which needs to consume a large amount of wood. Contents of the invention [0003] The present invention aims at the disadvantages of large wood consumption in the prior art, which is not conducive to environmental protection, and the processing of the pencil board is complicated, and the labor intensity of the workers is high, etc., and provides a kind of waste material produced in the process of recycling the pencil as the raw material of the pencil board, A large amount of wood can be saved, and the pencil board produced is environmentally friendly and non-toxic, without any ha...
