Calcium titanate nanometer fiber-acrylic fiber pulp-reinforced thermal insulation mortar and preparation method thereof

Abstract

The invention discloses calcium titanate nanometer fiber-acrylic fiber pulp-reinforced thermal insulation mortar and a preparation method thereof. The calcium titanate nanometer fiber-acrylic fiber pulp-reinforced thermal insulation mortar is prepared from 19-27 parts by weight of waste calcium silicate boards, 12-19 parts by weight of acrylic fiber pulp, 14-21 parts by weight of copper mine tailings, 10-15 parts by weight of calcite, 13-20 parts by weight of furnace cinder, 8-14 parts by weight of white mud, 10-15 parts by weight of calcium titanate nanometer fibers, 7-11 parts by weight of ammonium alginate, 16-22 parts by weight of basalt slag, 9-16 parts by weight of stone coal cinder, 5-10 parts by weight of fluorgypsum, 51-58 parts by weight of low-heat Portland blast furnace slag cement, 11-18 parts by weight of carbonized rice hull and 10-15 parts by weight of sodium polyacrylate. Through use of calcium titanate nanometer fibers and acrylic fiber pulp in thermal insulation mortar, good enhancement effects are obtained, thermal insulation mortar compressive strength is improved and corrosion resistance and high temperature resistance of the thermal insulation mortar are improved. The thermal insulation mortar has high compressive strength, good corrosion resistance, high temperature resistance, water resistance and aging resistance.

Description

Technical field [0001] The invention relates to a thermal insulation mortar reinforced by calcium titanate nanofibers and acrylic fiber pulp and a preparation method thereof, and belongs to the field of building materials. Background technique [0002] Insulation mortar is a new type of building insulation material developed in recent years. Insulation mortar is made of some materials with better thermal insulation performance as aggregates, cementing materials, additives and water in a certain proportion. Thermal insulation mortar. With the rapid development of my country's construction industry, building energy conservation has attracted more and more attention. Research on thermal insulation mortar is also gradually deepening. The development of thermal insulation mortar with good performance has become one of the effective measures to solve energy waste and improve the living environment. The current traditional thermal insulation mortars in my country mainly include polyph...
