Embodiment 1

[0040] An environment-friendly composite board is made by the following steps:

[0041] a. Separately clean 100Kg of waste polypropylene and 50Kg of waste polyethylene plastics, dry them, crush them to less than 8mm, and mix them uniformly to obtain product A;

[0042] b. Wash and dry 300Kg thyme traditional Chinese medicine waste residue and 300Kg wormwood traditional Chinese medicine waste residue to be below 4mm, and mix them uniformly to obtain product B;

[0043] c. Mix product A and product B evenly and send them to the feed port of the screw extruder, and extrude at a screw speed of 70r / min and a barrel temperature of 175°C to obtain product C;

[0044] d. After calendering product C under a pressure condition of 4.8 MPa by a sheeting roller and two cooling rollers, the finished product is obtained by heating and leveling, cooling by arranging rollers, and trimming and shearing.

Embodiment 2

[0046] An environment-friendly composite board is made by the following steps:

[0047] a. Separately wash 150Kg of waste polypropylene and 80Kg of waste polyethylene plastics, dry them, crush them to less than 8mm, and mix them uniformly to obtain product A;

[0048] b. Wash and dry 400Kg thyme traditional Chinese medicine waste residue and 350Kg wormwood traditional Chinese medicine waste residue to be below 4mm, and mix uniformly to obtain product B;

[0049] c. Mix product A and product B evenly and send them to the feed port of the screw extruder, and extrude at a screw speed of 70r / min and a barrel temperature of 175°C to obtain product C;

[0050] d. After calendering product C under a pressure condition of 4.8 MPa by a sheeting roller and two cooling rollers, the finished product is obtained by heating and leveling, cooling by arranging rollers, and trimming and shearing.

Embodiment 3

[0052] An environment-friendly composite board is made by the following steps:

[0053] a. 200Kg of waste polypropylene and 100Kg of waste polyethylene plastics are sorted, cleaned, dried, crushed to less than 8mm, and mixed uniformly to obtain product A;

[0054] b. Wash and dry 500Kg of thyme traditional Chinese medicine waste residue and 400Kg of mugwort Chinese medicine waste residue to below 4mm, and mix uniformly to obtain product B;

[0055] c. Mix product A and product B evenly and send them to the feed port of the screw extruder, and extrude at a screw speed of 70r / min and a barrel temperature of 175°C to obtain product C;

[0056] d. After calendering product C under a pressure condition of 4.8 MPa by a sheeting roller and two cooling rollers, the finished product is obtained by heating and leveling, cooling by arranging rollers, and trimming and shearing.

Abstract

The invention discloses an environment-friendly composite board which comprises the following raw materials in parts by weight: 10-15 parts of waste and old polypropylene plastics, 10-15 parts of waste and old polyvinyl plastics, 30-50 parts of waste residues of thyme traditional Chinese medicine and 30-45 parts of waste residues of wormwood traditional Chinese medicine. The environment-friendly composite board is obtained by mixing the raw materials and performing plastic extruding and rolling on the mixed raw materials. The composite board is mainly used for a supporting template and a wallbody template when concrete is poured in construction, and the waste residues of the thyme traditional Chinese medicine and the waste residues of the wormwood traditional Chinese medicine are added into ingredients, so that the composite board has aromatic odor of plants and also has better antibacterial property and sterilizing effect, the composite board is prevented from being mildewed, the radioactivity of the composite board is reduced, and bodies of production workers and installers of the composite board can be protected; the composite board is low in cost of the raw materials, the pollution to the environment caused by the waste residues of the traditional Chinese medicines and the waste and old plastics is reduced, and the 'high-value' utilization of the waste residues of the traditional Chinese medicines and the waste and old plastics are achieved. Additionally, an environment-friendly construction material is added for the construction, so that the composite material has better ecological benefits and economic benefits.

Description

technical field [0001] The invention relates to a composite board for building, in particular to an environment-friendly composite board. Background technique [0002] At present, the support formwork and wall formwork used in pouring concrete in construction projects are mostly bamboo plywood and wood formwork, and the loss is as high as 60% to 70%, resulting in a serious waste of resources. Urgently waiting for a new type of material for waste utilization, pollution reduction and resource saving to solve the problem. Chinese patent 201310308067.7 discloses "a composite board made of waste plastics and phosphorus slag fine powder and its production method", and Chinese patent 201310338753.9 discloses "a composite board made of modified phosphorus slag and waste plastics and its production method". It uses waste plastics and industrial waste slag and phosphorus slag as raw materials to produce composite boards; Chinese patent 201510614951.2 discloses "A Modified Antimony Ta...
