Embodiment 1

[0016] Embodiment 1 (with reference to the corresponding raw materials and parts by weight of embodiment 1 in the table): each raw material is prepared according to the requirements of step (1) to prepare the material, with 30 parts of papermaking sludge, 30 parts of epoxy resin waste, 10 parts of wood Silk and / or bamboo silk, 5 parts of plant foaming pellets, 3 parts of triethylenediamine and 3 parts of calcium peroxide are mixed, fully kneaded and mixed in a kneader, and poured into a multi-layer press template for Hot pressing, pressure 1MPa, temperature 120°C, pressing for 15 minutes, unloading and stacking, curing for 24 hours, and then polishing and sanding the surface of the board.

Embodiment 2

[0017] Embodiment 2 also refers to the corresponding raw materials and parts by weight of Embodiment 2 in the table. The method is basically the same as that of Embodiment 1, but the reinforcing material added is 20 parts of plastic braided short material, the pressure of hot pressing is 0.6 MPa, the temperature is 100 ° C, and the time 20min.

Embodiment 3

[0018] The basic method of Example 3 is the same as before, but 20 parts of brown silk are added, the hot pressing temperature is 110° C., the pressure is 0.8 MPa, and the time is 10 minutes.

[0019] For the remaining examples 4-7, refer to the raw materials and weight ratio values ​​in the table, and make boards according to the basic method of Examples 1-3. After the boards are polished and sanded, then use unsaturated resin to paint the board surface or transfer printing or Make surface beautification by punching out hole patterns and other methods. This board is especially suitable as a flower bed enclosure in the landscape area. The length and width of the board are determined by mold making according to the design requirements, and the thickness is 1-2cm.

[0020] Among the seven examples, examples 1, 3, and 5 are preferred.

Abstract

The invention discloses a production method of paper mill sludge landscape ornamental material, which is characterized by comprising the following raw materials according to parts by weight: 30 to 40 parts of paper mill sludge, 30 to 40 parts of epoxy resin leftover, 10 to 20 parts of reinforcing material, 5 to 7 of plant foaming granules, 3 to 5 of triethylenediamine and 3 to 5 parts of calcium peroxide. The production method comprises the following five steps of: first, preparing material; second, mixing; third, moulding and heat pressing; fourth, stacking and curing; and fifth, surface treatment. The prepared plank material is particularly applicable to be used as a flower bed boarding of the landscape area, is beautiful and elegant, and has low cost and water resistance and appropriate strength. The landscape ornamental plate is produced by the method, thus making waste profitable, not only solving the environmental problem, but also solving the problem of material for producing the artificial board; and the plank material has lighter weight and low energy dissipation in production.

Description

technical field [0001] The invention relates to a method for pressing artificial panels with papermaking sludge, resin waste and fiber reinforcement. Background technique [0002] In recent years, the purpose of turning papermaking sludge into treasure is to solve environmental sanitation problems and at the same time solve the problem of raw materials for wood-based panels. Therefore, this kind of research has become more and more popular, and different technical solutions have been contributed to society. For example, CN101423354 discloses a method for mixing building materials with papermaking sludge and lime, steel slag, carbide slag, and waste cement; in the disclosed technical scheme of CN101332622, papermaking sludge needs to be dried twice at a high temperature of 105°C, CN1724451 and CN1408675 Each discloses a technical solution for producing sintered bricks from papermaking sludge, which needs to be sintered into bricks at a high temperature of 600-700°C, or even 9...
