Problems solved by technology

The existing advertising boards are made of non-woven fabric or cardboard, which are easy to change color in the outdoor environment, affecting normal use, and waste manpower and material resources when replacing
Moreover, in the production process of many existing advertising boards, organic spraying agents, printing agents and adhesives are usually used, resulting in excessive formaldehyde emission from the finished advertising boards and endangering the environment.
Moreover, most of the existing advertising boards are flammable and prone to fire

Abstract

The invention belongs to the technical field of plates, and discloses a composition for preparing a PVC board and a preparation method of the composition. The composition comprises the following components in parts by weight: 500-1000 parts of PVC resin, 400-600 parts of calcium powder, 4-8 parts of oxidized polyethylene, 20-50 parts of a stabilizer, 4-8 parts of a surface lubricating auxiliary agent, 3-8 parts of wax, 6-10 parts of an internal lubricating auxiliary agent, 3-7 parts of a lubricant, 2-6 parts of zinc oxide, 20-120 parts of a regulator, 0.1-0.5 part of toner and 15-40 parts of atoughening agent. The finished board material is prepared through the steps of raw material mixing, raw material reaction, plate shaping, film covering of a plate material, obtainment of the finishedboard material, etc. The PVC board prepared by using the preparation method provided by the invention has good waterproof and mildew-proof properties, is not easy to deform, has good oil stain-proofeffect, does not contain radioactive elements, does not release harmful substances, has good environmental protection performance, is non-flammable, and can be used for advertisement boards, cupboardsand the like.

Description

technical field [0001] The invention belongs to the technical field of boards, and in particular relates to a composition for preparing PVC boards and a preparation method thereof. Background technique [0002] Modern society has entered the information age, especially under the conditions of commodity market economy, a large amount of information is displayed by advertisements. Advertising boards are billboards used to attract customers to come to consume, and can also be used to promote policies and regulations, or to remind attention. Existing advertising boards are made of non-woven fabric or cardboard, and are prone to discoloration in the outdoor environment, affecting normal use and wasting manpower and material resources when replacing them. Moreover, in the production process of many existing advertising boards, organic spraying agents, printing agents and adhesives are usually used, resulting in excessive formaldehyde emission from the finished advertising boards ...
