Lightweight, heat-insulating, anti-seepage and pressure-bearing door and window frame joint sealant as well as preparation method, use method and application thereof

Abstract

The invention discloses a light thermal-insulation impervious pressure-bearing door and window frame joint sealant as well as a preparation method, a use method and application thereof. The door and window frame joint sealant is prepared from high-molecular polymer rubber powder, polyphenyl granules, cement, quartz powder, heavy calcium carbonate, kaolin, a powder defoaming agent, composite fibers, a water-retention thickening agent, starch ether and a water reducing agent. Wherein the composite fibers are polypropylene fibers, steel nanofibers and carbon fibers; the problems of water seepage, cracking, poor adhesion, poor load bearing and the like after seam filling of the door and window frame can be solved, and meanwhile, the high-strength light-weight performance is considered, the construction performance is high, no hanging is left, and the effects of high impermeability, high load bearing and high heat preservation are achieved. The preparation method of the door and window frame caulking glue comprises the following steps: mixing the components, stirring at a high speed to obtain a powdery finished product, and finally bagging and storing, the process is simple and convenient, the door and window frame caulking glue is suitable for large-scale production, and the transportation energy consumption can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a light-weight heat-retaining, anti-seepage and pressure-bearing door and window frame gap filler and its preparation method, use method and application. Background technique [0002] The caulking of door and window frames has always been a difficult problem at home and abroad. Nowadays, self-mixed cement mortar is commonly used to fill the door and window frames. Self-mixed cement mortar produces a lot of dust pollution and construction waste during the mixing process, which seriously endangers the health of construction workers and the urban environment. In addition, if self-made cement mortar is used to fill joints, phenomena such as mortar sagging, water seepage, and cracking often occur, which seriously affect the quality of decoration. In order to solve the problems of water seepage and cracking, many construction workers do waterproof treatment before construction, and...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the deficiencies of the prior art, one of the purposes of the present invention is to provide a light-weight thermal insulation, anti-seepage and pressure-bearing door and window frame joint sealant, which can solve the problems of water seepage, cracking, poor bonding, and poor load-bearing after the door and window frames are filled. While taking into account the high-strength and light-weight performance, it has strong construction performance, no hanging, high impermeability, high load-bearing, and high heat preservation; the second purpose of the present invention is to provide a light-weight heat preservation, impermeability, and pressure-bearing door and window The preparation method of the frame sealant only needs to mix and stir the raw materials in order to obtain the powder and pack it, which is suitable for large-scale preparation; the third purpose of the present invention is to provide a light-weight thermal insulation, impermeability and pressure-resistant door and window frame sealant It can be used by mixing the finished product with water, which reduces construction waste; the fourth purpose of the present invention is to provide a light-weight thermal insulation, anti-seepage and pressure-bearing door and window frame sealant, which is specially used for door and window frame sealants bonding
