Abstract

The invention relates to a preparation method of a high-strength and chemical-corrosion-resisting joint mixture and belongs to the technical field of preparation of building materials. The preparationmethod comprises the following steps: firstly, carrying out catalytic reaction on propylene oxide; then adding ethylene oxide and mixing and reacting to obtain reaction filtrate; then carrying out high-temperature explosion on straws to obtain a dry steam exploded product; carrying out hydrolysis reaction on the dry steam exploded product and alkali liquid; then adding organic silane and tetraethyl orthosilicate, and mixing, reacting and concentrating to obtain condensed liquid; finally, enabling boron carbide, phenolic resin, mixed suspension liquid to react to prepare the high-strength andchemical-corrosion-resisting joint mixture. According to the high-strength and chemical-corrosion-resisting joint mixture, the propylene oxide and the ethylene oxide are catalytically complexed, so that the cohesive property of an organic solution is enhanced; the joint mixture and a base material can generate more covalent bonds, hydrogen bonds and intermolecular interaction forces to adsorb, sothat the bonding effect is reinforced, cellulose and lignin in the straws are separated, so that the dynamical strength and mechanical strength of the joint mixture are effectively enhanced and the joint mixture is difficult to crack; the joint mixture has a wide application prospect.

Description

technical field [0001] The invention relates to a preparation method of a high-strength chemical corrosion-resistant caulking agent, which belongs to the technical field of building material preparation. Background technique [0002] With the development of society, tiles have become one of the most commonly used materials in architectural decoration. In modern buildings, tiles have been widely used in the decoration of the interior and exterior walls and floors of buildings. In order to avoid hollowing between tiles due to thermal expansion and contraction, a certain gap should be reserved between tiles. , the gap needs to be filled with tile grout. [0003] The main components of tile grout are cementitious materials, fillers and additives. The cementitious material imparts adhesive force to the caulking agent, the additives endow the caulking agent with good workability, flexibility and other functions, and the filler has a great influence on the volume stability and fi...
