Problems solved by technology

[0003] With the advancement and development of science and technology, we have continuously improved and innovated the materials and processing technology of drainage boards. The compressive strength and overall mechanical properties of today's polystyrene drainage boards have been significantly improved, but with the deepening of research we It was found that the chemical stability of polystyrene is relatively poor, it is not resistant to grease, and it is not easy to biodegrade, and it is easy to pollute the environment, which has brought us great troubles.

Abstract

The invention discloses a biodegradable drain board, and a preparation method thereof. The biodegradable drain board comprises components such as polystyrene emulsion, modified polylactic acid, and modified wood fiber. The conventional drain boards are prepared from polystyrene; polystyrene is poor in chemical stability, no grease resistance is achieved, biodegradation is difficult to realize, andenvironment pollution is easily caused. According to the preparation method, wood fiber is added, so that toughening effect on polylactic acid and polystyrene is achieved, at the same time, wood fiber is cheap, and is easily biodegraded, and waste recycling is realized. The formula of drain board is improved, the preparation technology is optimized, the obtained biodegradable drain board possesses excellent corrosion resistance, water resistance, mechanical performance, excellent biodegradability, and high practicality, and is friendly to the environment.

Description

technical field [0001] The invention relates to the technical field of drainage board processing, in particular to a biodegradable drainage board and a preparation process thereof. Background technique [0002] Plastic drainage boards are generally made of polystyrene (HIPS) or polyethylene (HDPE) as a plastic bottom plate, and then stamped into a conical protrusion or a raised point (or hollow cylindrical hole) of a stiffener. An indispensable tool in road construction. [0003] With the advancement and development of science and technology, we have continuously improved and innovated the materials and processing technology of drainage boards. The compressive strength and overall mechanical properties of today's polystyrene drainage boards have been significantly improved, but with the deepening of research we It was found that the chemical stability of polystyrene is relatively poor, it is not resistant to grease, and it is not easy to biodegrade, and it is easy to pollut...
