Problems solved by technology

However, most of the existing joint fillers are made of cement, together with the additives commonly used in cement, which have defects in environmental resistance and environmental protection, and have great limitations in application occasions, safe use, and long life.
When it is used in the gaps of video wall tiles, because it is affected by the sound, it is easy to crack and fall off due to the shock, which affects the service life

Abstract

The invention discloses a gap filler for video walls. A preparation method of the gap filler comprises the following steps: 1, preparing a base material: crushing quartz sand and limestone to 300-500 meshes, adding open-cell expanded perlite, hydroxypropyl methyl cellulose, an inorganic aluminum salt waterproof agent and aluminum magnesium silicate, and uniformly stirring; 2, preparing an auxiliary material: mixing an ethylene-vinyl acetate copolymer, acrylic resin, fumed silica, RTV organic silica gel and a brightener, 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 joint filler, in particular to a joint sealant for a film and television wall, 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, together with additives commonly used in cement, which have the disadvantages of environmental resistance and environmental protection, and have great limitations in application occasions, safe use, and long life. When it is used in the gaps of video wall tiles, because it is affected by sound, it is easy to crack and fall off due to shock, which affects the service life. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a caulking agent for film and television walls wi...
