Embodiment 1

[0029] At room temperature, add 12 parts of functionalized iron red mud, 3 parts of Tween 60 and 7 parts of n-pentane to 100 parts of phenolic resin, stir at high speed for 5 min at a stirring speed of 1000 r / min, and then add 10 parts of curing agent , continue to stir for 1 min, then pour it into a mold of a certain shape, put the mold into an oven, and pre-cure the phenolic resin at 60 ° C, and remove part of the volatile components and excess solvent at the same time to obtain a prepreg; The obtained prepreg was placed on a molding machine, and kept under a pressure of 0.3 MPa and a temperature of 80°C for 5 minutes to complete the entire foaming process and obtain a functionalized iron red mud reinforced and toughened phenolic foam insulation board.

Embodiment 2

[0031] At room temperature, add 13 parts of functionalized iron red mud, 4 parts of Tween 80 and 7 parts of n-pentane to 100 parts of phenolic resin, stir at high speed for 5 min at a stirring speed of 1000 r / min, and then add 15 parts of curing agent , continue to stir for 1 min, then pour it into a mold of a certain shape, put the mold into an oven, and pre-cure the phenolic resin at 50 ° C, and remove part of the volatile components and excess solvent at the same time to obtain a prepreg; The obtained prepreg was placed on a molding machine, and kept under a pressure of 0.3 MPa and a temperature of 70°C for 5 minutes to complete the entire foaming process and obtain a functionalized iron red mud reinforced toughened phenolic foam insulation board.

Embodiment 3

[0033] At room temperature, add 14 parts of functionalized iron red mud, 5 parts of Tween 80 and 8 parts of isopentane to 100 parts of phenolic resin, stir at high speed for 5 min at a stirring speed of 1000 r / min, and then add 18 parts of curing agent , continue to stir for 1min and then pour it into a mold of a certain shape; put the mold into an oven, pre-cure the phenolic resin at 50°C, and remove part of the volatile components and excess solvent at the same time to obtain a prepreg; Put the prepreg into the molding machine, and keep it under the pressure of 0.3 MPa and the temperature of 80°C for 5 minutes to complete the whole foaming process, and obtain the functionalized iron red mud reinforced and toughened phenolic foam insulation board.

Abstract

The invention relates to an industrial waste reinforced toughened phenolic foam insulation board and a preparation method thereof. The industrial waste is ferric red mud which is pollutant waste produced in the aluminum oxide production process, and the output of the ferric red mud is high. In order to improve the dispersion and increase the consumption of the ferric red mud in the phenolic resin, the ferric red mud is milled by a ball mill into extremely-fine particles with a particle size of 1 to 1.5 micrometers, and a coupling agent is used for functionalizing the surface of the extremely-fine particles. The functionalized ferric red mud in the phenolic resin curing process and the phenolic resin form a chemical bond, so that the combination force between the ferric red mud and the phenolic resin is increased, and the comprehensive performance of the phenolic resin is improved. Not only the strength and flame retardant property of the phenolic foam insulation board are greatly improved, and an application standard of the heat insulation material for a building outer wall can be satisfied; and moreover, a great number of industrial waste ferric red mud is consumed, the environmental pollution is reduced, the production cost is decreased, and the application prospect is wide.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials for building exterior walls, and in particular relates to an industrial waste reinforced and toughened phenolic foam thermal insulation board and a preparation method thereof. Background technique [0002] At present, insulation materials such as EPS, XPS polystyrene foam, polyurethane foam, glass wool and mineral wool are commonly used as insulation materials for building exterior walls. Polystyrene foam and polyurethane foam are flammable, and inorganic rock wool has poor thermal insulation effect and is easy to absorb moisture and rot. These shortcomings greatly restrict their application as building exterior wall insulation materials. Therefore, it is imminent to find a new type of building exterior wall insulation material with excellent performance. [0003] As a new generation of thermal insulation materials, phenolic foam has the advantages of light weight, low smoke ...
