Abstract

The invention relates to a calcium silicate board and a preparation method thereof. The calcium silicate board is prepared from the following raw materials: 47-50 parts of quartz sand, 15-18 parts ofcement, 12-16 parts of fly ash, 15-18 parts of ultrafine ceramic fibers and 3-7 parts of paper fibers. According to the calcium silicate board, quartz sand is used as a main raw material; fly ash is taken as an auxiliary material, under the synergistic effect of cement, the superfine ceramic fibers and the paper fibers, the effects of all the raw materials can be fully played, the refractory temperature of the superfine ceramic fibers can be 1300 DEG C or above, and when the superfine ceramic fibers are applied to the calcium silicate board, the temperature resistance and the refractory time of the calcium silicate board are improved through the synergistic effect of all the raw materials; the fly ash and the paper fibers are added, so that the crack rate of the calcium silicate board canbe reduced; the preparation method of the calcium silicate board is simple, easy to operate, low in production cost and easy for industrial production.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a calcium silicate board and a preparation method thereof. Background technique [0002] Calcium silicate board is a new type of inorganic building material with excellent fire resistance, moisture resistance and sound insulation. According to the composition of silicate, calcium silicate board is divided into two categories, one is tobermullite calcium silicate board; the other is hard calcium silicate type calcium silicate board. [0003] Calcium silicate board can be used as thermal insulation material or decorative material. Calcium silicate board for thermal insulation is mainly used for external wall hanging board, external wall veneer, etc. Decorative calcium silicate boards are mainly used for suspended ceilings, ceilings, house partition walls, and indoor floors. With the continuous expansion of the thermal insulation and decorative finished boar...
