Embodiment 1

[0013] Proportion: The mass ratio of rock wool waste slag to rock wool resin glue is 3:2; the mass ratio of rock wool waste slag to waterproofing agent is 15:4. Weigh each raw material.

[0014] Put the weighed rock wool slag into the crusher and break it into cotton wool with a length of 1~5cm, then spray the weighed rock wool resin glue and waterproof agent on the cotton wool, and then stir it with a mixer at 1500 rpm for 2 After 10 minutes, spread the mixed primary material on the formwork, and press it with a 10t hot press at 100°C for 5 minutes to form a rock wool waste slag board.

Embodiment 2

[0016] Proportion: The mass ratio of rock wool waste slag to rock wool resin glue is 6:1; the mass ratio of rock wool waste slag to waterproofing agent is 15:1. Weigh each raw material.

[0017] Put the weighed rock wool slag into the crusher and break it into cotton wool with a length of 1~5cm, then spray the weighed rock wool resin glue and waterproof agent on the cotton wool, and then stir it with a mixer at 1500 rpm for 2 After 10 minutes, spread the stirred raw material on the formwork, and press it with a 10t hot press at 100°C for 3 minutes to form a rock wool waste slag board.

Embodiment 3

[0019] Proportion: The mass ratio of rock wool waste slag to rock wool resin glue is 4:1; the mass ratio of rock wool waste slag to waterproofing agent is 5:1. Weigh each raw material.

[0020] Put the weighed rock wool slag into the crusher and break it into cotton wool with a length of 1~5cm, then spray the weighed rock wool resin glue and waterproof agent on the cotton wool, and then stir it with a mixer at 1500 rpm for 2 After 10 minutes, spread the stirred raw material on the formwork, and press it with a 10t hot press at 100°C for 4 minutes to form a rock wool waste slag board.

[0021] The rock wool waste slag boards in the above three embodiments are hot-pressed to produce rock wool waste slag boards with a length of 1220 mm and a width of 600 mm. Its appearance dimensions are measured: length and width deviations are less than ±2.0mm, thickness has no negative deviation, positive deviation is less than 2.0mm, diagonal deviation is less than 3.0mm, side straightness de...

Abstract

The invention overcomes defects of the waste cotton treatment method in the prior art and provides a rock wool waste residue plate and a preparation method thereof. The rock wool waste residue plate comprises rock wool waste residue, rock wool resin adhesive and a waterproof agent. The preparation method comprises the following steps: the rock wool residue is placed in a crusher for being smashed to cotton fibers with thread length of 1-5 cm; then the rock wood resin adhesive and the waterproof agent are sprayed to the cotton fibers; the cotton fibers are stirred for 2 minutes by a stirrer at the speed of 1,500 r / m; and the stirred raw material is flatly spread on a template, and is thermally pressed for 3-5 minutes by a 10 t hot press at the temperature of 100 DEG C to form the rock wool waste residue plate. The rock wool waste residue is produced to a thermal insulation plate which has the function of A-grade fire protection and a good thermal insulation effect; and the prepared rock wool waste residue plate can be applied in the fields, such as wall filling, roof heat insulation, outer wall heat insulation, inner wall sound insulation and the like. The rock wool waste residue plate and the preparation method thereof change wastes into wealth, achieve the solid waste recycling, and create excellent economic and social benefits.

Description

technical field [0001] The invention relates to a building material, in particular to a rock wool board and a preparation method thereof. Background technique [0002] During the rock wool production process, a large amount of waste cotton will be produced. Cotton waste takes up a lot of space and is difficult to handle. At present, the general treatment method is landfill, but landfill occupies land, and the treatment cost is high. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overcome the shortcomings of the waste cotton treatment methods in the prior art, and to provide a rock wool waste slag board and its preparation method. The method of the present invention can turn waste cotton into treasure and realize solid waste recycling . [0004] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a rock wool waste residue board, which consists of rock ...
