Abstract

This invention relates to dry powder mortar characterizing that it's good in operational performance, good in construction and compatible with plaster stones, which takes cement and quartz sand as the main materials and adds white lime, hemihydrate, heavy CaCO3 to improve the compatibility with gypsum base and uses ethane-vinyl ecetate copolymer powder latex, alkyl-propyl fibrin aether, polypropylene fiber to increase binding strength and integrity of mortar and prevent cracking.

Description

Dry powder mortar for plastering gypsum wall
Technical field
The present invention relates to a kind of dry powder mortar for plastering, belong to a kind of material of construction.
Technical background
At present, building materials of gypsum is as a kind of novel material of construction, with the application of fundamental characteristics in modern construction engineering such as its good heat insulation, fire prevention, lightweight, adjusting atmospheric moisture, green safety environmental protection more and more widely.Have the situation that much need further plaster on gypsum building material and decorate in actual application, for many years, people are according to traditional operating experience, and the plastering material of using on building materials of gypsum is still sand-cement slurry.But, the water-intake rate of plastering is high, can reach 50% of own wt, plaster with conventional cement mortar, because gypsum suction is difficult to operation when not only constructing, and because the intensity of sand-cement slurry after solidifying is too high, and the intensity of plastering is lower, and both are difficult to be bonded to a firm integral body.Simultaneously because the sand-cement slurry coat of plaster and the plastering coefficient of expansion differ too big, the construction work meeting will occur in back about 1 year (i.e. the freeze-thaw cycle cycle) of coming into operation that serious be full of cracks, hollowing even coat of plaster are large-area to come off.
Summary of the invention
A kind of compound special-purpose dry-mix of on gypsum building material, plastering that purpose of the present invention provides in order to solve above-mentioned existing technical deficiency just.
The objective of the invention is by the formulated dry-mix of following raw materials by weight percent:
Quartz sand (0.05-0.5mm) 50-56%
Ordinary Portland cement 20-28%
White lime 8-12%
Water-ground limestone 4-6%
Semi-hydrated gypsum 4-6%
Ethylene-vinyl acetate copolymerization powder latex 1.4-2.0%
Hydroxypropyl methyl cellulose ether 0.2-0.4%
Polypropylene fibre (3-5mm) 0.8-1.2%
According to the above ratio various starting material are prevented fully stirring, mixed and make a kind of motar that is exclusively used in gypsum building material into colter formula Agravicmixer.
The mortar for preparing according to the above ratio and clear water stirred according to about 4: 1.3 mixed promptly can be used on gypsum building material, plastering.Thickness generally is advisable at 3-5mm.This plaster wall motar for preparing according to the above ratio has good water-retaining property, cohesive strength height, thin layer and plasters, with building materials of gypsum good consistency is arranged.Easy handling, reduction labour intensity during construction, the coat of plaster surface can be done waterproof, sticking brick etc. routinely.Solve a difficult problem of on gypsum building material, plastering, will promote the application of building materials of gypsum in construction work effectively.

Claims (2)

1. a dry powder mortar for plastering gypsum wall comprises quartz sand, ordinary Portland cement, white lime, water-ground limestone, semi-hydrated gypsum, ethylene-vinyl acetate powder latex, hydroxypropyl methyl cellulose ether, polypropylene fibre.It is characterized in that: the weight percent of each composition of dry powder mortar for plastering gypsum wall is quartz sand (0.05-0.5mm) 50-56%, ordinary Portland cement 20-28%, white lime 8-12%, water-ground limestone 4-6%, semi-hydrated gypsum 4-6%, ethylene-vinyl acetate copolymerization powder latex 1.4-2.0%, hydroxypropyl methyl cellulose ether 0.2-0.4%, polypropylene fibre (3-5mm) 0.8-1.2%.
