Embodiment 1

[0041] This embodiment provides a kind of additive for building materials, comprising:

[0042] Material selection: organic resins, dyes, and paint wastes are used as raw materials, and the solid content of raw materials is 0.5wt%, pH=9;

[0043] Demulsification: Use sodium hydroxide to adjust the pH of the raw material to pH 10 to obtain material A;

[0044] Flocculation: Add polyferric chloride to material A to pH=4, then add polyaluminum chloride to pH=2 to obtain material B;

[0045] Separation: after adjusting the pH of material B to 7, calcium carbonate is added therein so that calcium carbonate accounts for 10 wt% of material B, and then solid-liquid separation is carried out; the material after solid-liquid separation is crushed and dried to obtain additives for building materials , and the drying temperature is 55°C.

Embodiment 2

[0047] This embodiment provides a kind of additive for building materials, comprising:

[0048] Material selection: organic resin wastes are used as raw materials, the solid content of raw materials is 4wt%, pH 8;

[0049] Demulsification: Use sodium hydroxide to adjust the pH of the raw material to pH 10.5 to obtain material A;

[0050] Flocculation: Add polyferric chloride to material A to pH=6, then add polyaluminum chloride to pH=3 to obtain material B;

[0051] Separation: after adjusting the pH of material B to 8, calcium carbonate is added therein so that calcium carbonate accounts for 2wt% of material B, and then solid-liquid separation is carried out; the material after solid-liquid separation is crushed and dried to obtain an additive for building materials , and the drying temperature is 65°C.

Embodiment 3

[0053] This embodiment provides a kind of additive for building materials, comprising:

[0054] Material selection: dyes, paint wastes and organic resin wastes are used as raw materials, the solid content of raw materials is 2wt%, pH=7;

[0055] Demulsification: Use sodium hydroxide to adjust the pH of the raw material to pH 10.25 to obtain material A;

[0056] Flocculation: Add polyferric chloride to material A to pH = 5, then add polyaluminum chloride to pH = 2.5 to obtain material B;

[0057] Separation: After adjusting the pH of material B to 7.5, calcium carbonate is added thereto so that calcium carbonate accounts for 1 wt% of material B, and then solid-liquid separation is carried out; the material after solid-liquid separation is crushed and dried to obtain additives for building materials , wherein the drying temperature is 45°C.

[0058] The building material additive that embodiment 1-3 obtains is detected, and the results are as follows:

Abstract

The invention discloses an additive for a building material and the building material containing the same. The building material comprises an aggregate and the additive, wherein the aggregate is clay,fly ash or sand; the building material and the aggregate are mixed to be processed into ceramsite, baking-free bricks, roofing tiles and the like, the additive is added to the building material, theexploitation quantity of sand and gravel is reduced, and available resources can be effectively utilized.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to additives for building materials and building materials thereof. Background technique [0002] With the development of the construction industry, the demand for building materials is also increasing, and the demand for raw materials such as sand and gravel is also increasing. The over-exploitation of sand and gravel has a significant impact on the environment. In addition, in the material industry, many by-products, semi-finished products and expired products (HW13 organic resin, HW12 paint) will produce a large amount of solid waste during the harmless treatment process. These solid wastes are generally treated by burning, but burning Firstly, a lot of resources are wasted, and secondly, the exhaust gas produced may pollute the environment, so these solid wastes continue to be used in a safer and more effective way. [0003] Therefore, from the perspective of sustainable d...
