Abstract

The invention discloses a method for preparing a joint sealant by utilizing construction wastes, i.e. building rubbish. The method comprises the following steps: taking the building rubbish as one part of a raw material and directly preparing the heat-insulating, mould-proof, moth-proof and anti-permeable joint sealant with low cost and environment friendliness by utilizing the existing sealant production line. The joint sealant has the joint sealing and bonding double functions, is adjustable in color and is convenient to construct.

Description

technical field [0001] The invention relates to a building material, in particular to a method for preparing a ceramic tile joint filler by using construction waste, that is, construction waste. Background technique [0002] Ceramic tiles have become one of the main building decoration materials for interior and exterior walls and floors. In order to avoid hollowing between ceramic tiles due to thermal expansion and contraction, a certain gap should be reserved between ceramic tiles and a sealant should be used to Wait for building materials to fill the gaps. At present, the main caulking agents are Portland cement, quartz powder, methyl cellulose, synthetic resin and anti-fungal agent, etc., such as "thermal insulation elastic caulking agent" (CN. "Preparation method of agent" (CN.96115732.1), "Multi-color sealant for construction" (CN200510100265.X), "Color tile sealant" (CN00117192.5), "A thermal insulation body and its manufacturing method" ( CN200710011250.5), "a meth...
