Abstract

A building exterior wall thermal insulation mortar with good rheology and a manufacturing method thereof, wherein the rheological good building exterior wall thermal insulation mortar comprises parts by weight: 200-240 parts of cement, 10-15 parts of superfine phosphorous slag powder, 5-5 parts of quicklime 10 parts, 100-120 parts of sand, 50-120 parts of modified expanded lightweight aggregate, 20-25 parts of rheological agent, 5-10 parts of hydroxypropyl cellulose, 2-parts of polycarboxylate high-performance water reducer 6 parts, 70-90 parts of water, the present invention uses modified ball milling agent to carry out ball milling to lightweight aggregate and its surface modification, makes lightweight aggregate particle size more uniform, and improves its surface wettability, and its bone The more uniform the surface wettability of the material, the more uniform its distribution in the slurry.

Description

technical field [0001] The invention relates to a building exterior wall thermal insulation mortar with good rheology, and belongs to the technical field of external wall thermal insulation mortar. Background technique [0002] External wall insulation system is currently the most widely used energy-saving technical measure in my country's building wall energy-saving. It is being popularized across the country and has made great contributions to building energy conservation. Currently on the market, the building insulation system with rubber powder polystyrene particle insulation mortar as the insulation layer occupies a considerable proportion in industrial and civil buildings. But, the external wall insulation mortar sold on the market is not uniform because of the uneven distribution of light materials, which causes the unstable defect of product insulation performance. Thereby there is an urgent need in the market for an exterior wall insulation mortar that improves pro...
