Flame-retardant high-strength wood-plastic profile and preparation method thereof

Abstract

The invention provides a flame-retardant high-strength wood-plastic profile and a preparation method thereof, and relates to the technical field of wood-plastic profiles. The problems that an existing wood-plastic profile does not have a production date recording structure, when the wood-plastic profile applied to a guardrail has an installation problem, warning is generally carried out through a warning board, but the warning range of the warning board is only limited to a small section around, and the warning mode is not convenient are solved. The flame-retardant high-strength wood-plastic profile comprises a wood-plastic profile main body, and a date separation groove penetrating through the rear end face of the wood-plastic profile main body is formed in the middle of the front end face of the wood-plastic profile main body. The production date of the wood-plastic profile main body is recorded through the date separation groove, a date value identification groove A and a date value identification groove B, and a purchasing user can know the production date of the wood-plastic profile main body by watching the production date, so that the purchased wood-plastic profile main body is guaranteed to be in a quality guarantee time limit.

Description

technical field [0001] The invention belongs to the technical field of wood-plastic profiles, and more specifically relates to a flame-retardant high-strength wood-plastic profile and a preparation method thereof. Background technique [0002] Wood-plastic, that is, wood-plastic composite material, refers to a board that is hot-extruded after mixing plastic, wood powder, and additives in a certain proportion. [0003] The general service life of wood-plastic profiles is about 10 years, and its quality assurance is generally about 3 years. Within the 3-year time limit of quality assurance, because in order to reduce costs, some merchants recycle wood-plastic profiles that have exceeded the quality assurance time limit and refurbish them by spraying and other methods, and then sell them with new wood-plastic profiles. Wood-plastic profiles have a short service life and quality problems. Once they are used in certain safety protection areas, such as guardrails along rivers, it...
