Abstract

The invention discloses an imitation wood grain decorative plate and a preparation method thereof. The imitation wood grain decorative plate is prepared from the following raw materials in parts by weight: 40 to 60 parts of ardealite, 10 to 16 parts of coal ash, 10 to 14 parts of cement, 15 to 24 parts of yellow phosphorus slag, and 1 to 4 parts of calcined lime. The invention has the advantages that the imitation wood grain decorative plate is maintained under the condition that the pressure is 0.3 MPa, and the steam temperature is 128 to 132 DEG C, so that the quality and the finished product yield of the imitation wood grain decorative plate are remarkably improved, and low energy consumption, high productivity and low investment are achieved; meanwhile, through the maintenance method, the shrinkage rate of a base material in a dry environment and the expansion rate of the base material in a water-soaked environment are remarkably reduced, the compressive strength of the base material is enhanced, and the service life of the base material is prolonged.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an imitation wood grain decorative board and a preparation method thereof. Background technique [0002] In the phosphoric acid production process, every ton of P produced 2 o 5 Five tons of phosphogypsum are produced by-product, and the annual by-production of phosphogypsum by medium-sized phosphoric acid production enterprises is about 3.5 million tons. So much phosphogypsum not only requires a large slag dump, but also causes water pollution. At present, the most commonly used phosphogypsum treatment methods are as follows: [0003] The first method: Phosphoric acid paste is used to backfill the pit. According to statistics, when phosphogypsum is not used to backfill the mine shaft, the filling cost of the mine shaft accounts for 1 / 3 of the mining, and the filling material accounts for 80% of the filling cost. If phosphogypsum is used to fill the mine shaft, the...
