Abstract

The invention discloses a green, environmentally-friendly and discoloration and fading-free gap filler. A preparation method of the gap filler comprises the following steps: 1, preparing a base material: crushing quartz sand and an air purifying decoration material named Kasongshi to 300-500 meshes, adding glazed hollow beads, hydroxypropyl methyl cellulose, an inorganic aluminum salt waterproof agent and ferrous sulfate, and uniformly stirring; 2, preparing an auxiliary material: mixing an ethylene-vinyl acetate copolymer, acrylic resin, fumed silica, RTV organic silica gel and an antioxidant 1076, and uniformly stirring; and 3, selecting an iron oxide pigment according to the color type of the gap filler, adding the base material to a high speed shearing stirrer, sequentially adding the auxiliary material and the iron oxide pigment in a shearing stirring state, stirring at a shearing speed of 6000-8000RPM for 45-90min, and discharging to obtain the gap filler. Gap filling spaces are cleaned, gap filling seams are sprinkled with water until moisture, the gap filler and water are mixed according to a mass ratio of 1:(0.4-0.6) and are blended to form a viscous material, the viscous material is filled between tiles, water is sprinkled after the viscous material is dried, and then natural drying is carried out.

Description

technical field [0001] The invention relates to a construction sealant, in particular to a green, environment-friendly, non-discoloration and discoloration sealant, a preparation method and a use method. Background technique [0002] Because the caulking agent can perfectly repair the cracks or damages on the ground surface, and it can also be prepared in rich colors, it is more and more popular among customers. However, most of the existing joint fillers are made of cement and are equipped with common additives for cement. They have the disadvantages of environmental resistance and environmental protection. They are safe in application and use, and have long life and limitations. They are prone to discoloration and fading due to long-term oxidation. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides an environment-resistant, environment-friendly, non-discoloration and non-fading caulking agent, a preparation method and a...
