Abstract
The invention discloses an anti-sagging heat-insulation mortar based on beta-hemihydrated gypsum. The mortar comprises the following components in parts by weight: 100 parts of beta-hemihydrated gypsum, 5-30 parts of white cement, 60-100 parts of vitrified microsphere, 10-40 parts of quartz sand, 3-10 parts of re-dispersible latex powder, 0.1-0.5 part of cellulose ether, 0.1-0.5 part of poval, 0.05-0.3 part of citric acid, 0.05-0.5 part of polypropylene fiber, 0.05-0.3 part of starch ether, 0.05-0.3 of montmorillonite powder and 120-200 of water. According to the invention, the heat-insulation mortar has extremely good anti-sagging property and good anti-skating property through improvement of heat-insulation mortar components; and the heat-insulation mortar has good workability, thereby greatly improving the construction efficiency and bringing obvious progress for the field of modern building energy conservation materials.
Description
Technical field
The present invention relates to energy-saving building materials, specifically thermal insulation mortar.
Background technology
Thermal insulation mortar is take various light materials as aggregate, take cement as gelating material, admixes some property-modifying additives, mixes and a kind of premixing dry-mix of making through manufacturing enterprise.Be mainly used in building exterior wall heat preserving, have the advantages such as easy construction, good endurance.Present thermal insulation mortar is because the defective of component, often occurs sagging, the sliding problem such as drop down in mechanical execution, for construction brings great inconvenience, causes the problems such as its workability is poor, efficient is low.
Summary of the invention
For the existing deficiency of above-mentioned prior art, the purpose of this invention is to provide and a kind ofly can effectively prevent sagging, the sliding problem such as drop down, and have good workability, can improve the anti-sag thermal insulation mortar of operating efficiency.
For achieving the above object, technical scheme of the present invention is a kind of anti-sag thermal insulation mortar based on β-semi-hydrated gypsum, and its component is β-semi-hydrated gypsum 100 by weight; white cement 5～30, glass bead 60～100, quartz sand 10～40; redispersible latex powder 3～10; ether of cellulose 0.1～0.5, polyvinyl alcohol 0.1～0.5, citric acid 0.05～0.3; polypropylene fibre 0.05～0.5; starch ethers 0.05～0.3, montmorillonite powder 0.05～0.3, water 120～200.
Its component of anti-sag thermal insulation mortar of the present invention can reach better effect when being following value by weight: β-semi-hydrated gypsum 100; white cement 5～20, glass bead 70～90, quartz sand 20～40; redispersible latex powder 5～8; ether of cellulose 0.2～0.4, polyvinyl alcohol 0.1～0.3, citric acid 0.1～0.2; polypropylene fibre 0.05～0.3; starch ethers 0.05～0.15, montmorillonite powder 0.05～0.15, water 140～170.
Its component of anti-sag thermal insulation mortar of the present invention can reach best effect when being following value by weight: β-semi-hydrated gypsum 100; white cement 10, glass bead 80, quartz sand 30; redispersible latex powder 6; ether of cellulose 0.3, polyvinyl alcohol 0.2, citric acid 0.15; polypropylene fibre 0.1; starch ethers 0.1, montmorillonite powder 0.1, water 150.
Beneficial effect: the present invention is by to the improvement of thermal insulation mortar component, makes it have extraordinary anti-sag, performance is dropped down in antiskid, and has good workability, and greatly improved operating efficiency, for having brought significant progress in modern architecture energy-saving material field.
