Abstract

The invention discloses a polymer filled light material, and a method for manufacturing a partition wall by using the same. The polymer filled light material is formed by mixing a polyphenyl polymethylene polyisocyanate mixture and polyether polyurethane, the whole wall can be completely filled with the polymer filled light material, and the polymer filled light material has better functional effects of heat insulation, fire prevention, heat preservation, noise prevention, moisture prevention, water prevention and the like; and the manufacturing method of the polymer filled light partition wall is achieved through the steps of basal plane cleaning, positioning, light plate mounting, pre-buried hole pipeline mounting, grouting nozzle mounting, burdening, grouting, filling material reactionfoaming and nozzle dismounting, a complete dry operation mode is adopted, assembly type construction is adopted, and wallboards can be cut at will to adjust the width and the length.

Description

technical field [0001] The invention relates to the technical field of lightweight partition walls, in particular to a polymer-filled lightweight material and a method for making a partition wall. Background technique [0002] A partition wall is a wall that separates the interior spaces of a building. The partition wall is not load-bearing, and is generally required to be light, thin, and have good sound insulation performance. There are different requirements for the partition walls of different functional rooms, for example, the partition walls of the kitchen should be fire-resistant; the partition walls of the bathroom should be moisture-proof. The existing technology usually adopts the structure of lightweight cement sandwich composite panels, such as cement rock wool sandwich panels, cement polystyrene particle mortar sandwich panels, foamed cement sandwich panels, and cement expanded perlite sandwich panels. All are to add cement or rock wool board, and the prior ar...
