Problems solved by technology

"Research on the preparation of high-volume titanium-containing slag wall bricks with modified PS glue" In the article, polystyrene foam and organic solvents were used to initiate the reaction to produce modified PS glue as a binder to realize high-volume titanium-containing slag wall bricks The preparation of this kind of wall brick has a certain strength and flame retardant performance, but it only relies on the bonding effect of liquid PS glue and the hydration effect of titanium slag itself, the activity of slag has not been effectively stimulated, and the product strength The performance in other aspects has not been significantly improved, and it cannot meet the performance and safety requirements of high-end wall materials

Embodiment Construction

[0015] A composite slag thermal insulation wall material for reusing waste plastics, made of the following raw materials in parts by weight: blast furnace slag 80, modified expandable waste plastic particles 10, iron tailings 20, bauxite slag 5, lithium slag 3.5. Ordinary Portland cement10.

[0016] Among them, the modified expandable waste plastic particles are mixed with 1% sodium silicate and an appropriate amount of water, and then sent to the autoclave, and butane is added as a foaming agent, so that the foaming temperature: 65 ℃ , Saturation pressure: 0.5MPa, Saturation time: 1h The dry particles obtained by passing through the blowing agent and foaming.

[0017] The preparation method of the thermal insulation wall material of this embodiment comprises the following steps:

[0018] (1) The blast furnace slag, bauxite slag, lithium slag, and iron tailings are crushed and ground respectively, and passed through a 100-mesh sieve;

[0019] (2) Mix the powder prepared in s...

Abstract

The invention discloses a reutilized waste plastic composite slag thermal-insulation wall body material and a preparation method thereof. The wall body material is prepared by compositing metal smelting waste such as blast furnace slag, alumina slag, lithium slag, iron tailings with waste plastic. For improving the reutilization effect of the waste plastic, the waste plastic is foamed and is added with an alkaline exciting agent so as to prepare expandable waste plastic particles, the tenacity of a materials can be improved by virtue of the plastic particles, meanwhile, a gelatinization process can be promoted by virtue of the exciting agent carried by the particles, and the compatibility of the plastic particles in a gel material is improved. The wall body material prepared by virtue of the preparation method has high strength and good tenacity, is unlikely to crack and has certain waterproof ability and excellent thermal insulation and sound insulation effects, and the effective utilization of high-adding-quantity slag powder is realized.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a composite slag thermal insulation wall material for reusing waste plastics and a preparation method thereof. Background technique [0002] With the progress of society, the energy saving and emission reduction of building materials has become an important reform direction for my country to build a resource-saving society. Among them, building wall materials are recommended as important basic materials for building energy saving and environmental protection. Based on this, new wall materials Research is very important. At present, the more common wall materials include aerated concrete blocks, ceramsite blocks, small concrete hollow blocks, fiber gypsum boards, etc. These materials are mainly made of industrial waste such as fly ash, coal gangue, stone powder, and slag. main ingreadient. [0003] Slag is a by-product of metal smelting. Its annual discharge is astonis...
