preparation example Construction

[0027] Aiming at the new changes and demands of building energy-saving external wall structure, the present invention provides a kind of colored sand for building, its preparation method and its application, which uses the raw material of colored sand containing waste glass to carry out all-inorganic high-temperature sintering to prepare colored sand, which can realize Green recycling of waste glass; the prepared colored sand is mainly used for building exterior walls, and can also be used for building colored tiles and interior decoration.

[0028] The first purpose of the present invention is to provide a kind of colored sand for construction:

[0029] Colored sand is sintered from colored sand raw materials, which include: batch materials, adhesives and quartz sand; of which:

[0030] The batching material of the present invention includes waste glass, borax, antimony white and inorganic colorant, preferably only the above four components constitute the batching material; t...

Embodiment 1

[0051] The invention provides a kind of colored sand for building and its preparation method. It is prepared according to the mass ratio of waste glass to borax of 80:20, adding 7% chrome green and 2% antimony white, and mixing evenly to form a batch material. The mass fraction of the batch material accounts for 6% of the mass fraction of the quartz sand, and a 150,000-viscosity hydroxypropyl methylcellulose ether aqueous solution with a solid content of 0.1% is added. Put it in a 740°C kiln and bake it into green colored sand.

Embodiment 2

[0053] The invention provides a kind of colored sand for construction and its preparation method. It is prepared according to the mass ratio of waste glass to borax of 90:10, adding 1% cobalt oxide and 5% antimony white, and mixing evenly to become a batch material; the mass of the batch material accounts for the mass of quartz sand 3% of the fraction, add a 150,000-viscosity hydroxypropyl methylcellulose ether aqueous solution with a solid content of 0.3%. It is advisable to firmly grasp the critical point of agglomeration after the amount of aqueous solution is added and stirred. Put it in a kiln at 880°C and bake it into blue colored sand.

Abstract

The invention discloses building color sand, a method for preparing the same and application of the building color sand. The method includes uniformly mixing batch mixtures, adhesive and quartz sand with one another; roasting the batch mixtures, the adhesive and the quartz sand at the temperature of 740-880 DEG C, coating the quartz sand with the batch mixtures and coloring the quartz sand by thebatch mixtures to form the building color sand. The batch mixtures comprise waste glass, borax, antimony white and inorganic colorants. The building color sand, the method and the application have theadvantages that color sand raw materials with the waste glass are sintered at the high temperature in an all-inorganic manner to prepare the building color sand, and accordingly the waste glass can be recycled in a green manner; the building color sand prepared by the aid of the method mainly can be applied to building external walls and also can be used for color tiles for buildings, interior decoration and the like.

Description

technical field [0001] The invention relates to the technical field of building materials and preparation, in particular to colored sand for building, a preparation method and application. Background technique [0002] The thermal insulation material is placed outside the exterior wall of the building to form the external thermal insulation system of the external wall. Among them, the external thermal insulation system of the thin plastered external wall is the most widely used thermal insulation system; the construction method is to first paste the thermal insulation material on the external surface of the external wall, and then use The glass fiber mesh cloth strengthens the protection of the mortar to the insulation system, and finally forms the finishing layer on the outermost layer. The above-mentioned suspension insulation structure requires that the finishing layer should not be too heavy. In the relevant specifications of the external insulation engineering of thin p...
