Description

A kind of additive for preparing dry-mixed plastering mortar and its dry-mixed plastering mortar
Technical field
The invention belongs to building material technical field, especially relate to a kind of additive for preparing mortar and its be dry mixed Motar.
Background technology
At present, mortar architectural engineering using mainly has two kinds: a kind of is building-site from the mortar mixed, measuring accuracy Difference, quality is unstable, easily causes the quality accidents such as hollowing, crack;Another kind is the industrial metaplasia that national policy encourages to support That produces is dry mixed premixing mortar, and metering is accurate, steady quality, also has the advantages that the useless environmental protection of profit.Therefore, building is dry mixed premixing mortar As a kind of novel green construction material, it is used widely in China, particularly substantially no longer makes in city With the mortar of situ configuration, dry powder premixing mortar has been obtained for widely using, and is not required to manual stirring in use, both saved Material saving, and uniformly, and steady quality.But it is various in style that premixing mortar is dry mixed, quality is also uneven, and some intensity is not Height, cohesive force is poor, and some unit weight is bigger than normal, and some hygroscopicity are big, easy cracking hollowing after construction, and some heat insulating abilities are poor, or Application property is bad, and cost height etc. has become as the common fault of mortar quality, and the key that development is dry mixed premixing mortar is exactly additive Development, the current premixing mortar one side that is dry mixed producing only considered some performance that premixing mortar is dry mixed, do not have The comprehensive application property comprehensively considering dry-mixed mortar, mechanical property, storage, durability.
Content of the invention
The invention of this reality is intended at least solve one of technical problem present in prior art.For this reason, the present invention proposes one kind For preparing the additive of dry-mixed plastering mortar, including weight item it is: 4~6 parts of cellulose, 5~8 parts of air entraining agent, calcium lignosulfonate 4~ 6 parts, 2~3 parts of quick lime.
Further, described cellulose is methyl cellulose ether.
Further, described air entraining agent is triterpene saponin air entraining agent.
Further, also include 2~3 parts of water reducer weight item.
Further, 2~3 parts of sodium silicate weight item, 1~2 part of calcium chloride weight item are also included.
Further, also include 1~2 part of antibacterial weight item.
In addition we also, it has been proposed that a kind of dry-mixed plastering mortar, the weight item comprising component is: 5~7 parts of triple superphosphate, cement 11~16 parts, 3~6 parts of flyash, 8~13 parts of phosphorus ore slag, 40~50 parts of sand, 1~4 part of arbitrary additive as previously described.
Further, described flyash is second class powered coal ash.
Further, described sand adopts the fluvial sand that particle diameter is that 2.5mm~2.7mm and maximum particle diameter are less than 4mm.
A kind of additive for preparing dry-mixed plastering mortar of proposition proposed by the present invention is methylcellulose compared with multicomponent Ether, it can make motar obtain suitable water-retaining property and denseness, so that moisture is progressively discharged within very long a period of time, from And ensure the combination of mortar and substrate, the surface activity of methyl cellulose ether ensure that mineral Binder Materials in whole system all Even distribution, as a kind of protecting colloid, methyl cellulose ether wraps solid particle, so that system is more stable, with water knot Sag resistance can be played after conjunction, effectively prevent motar from producing crack in condensation process;Add air entraining agent, improve The workability of mortar, adds calcium lignosulfonate, can also improve the cementability of mortar while improving mortar workability, uses in summer When being used in combination with water reducer can inhibition of slump-loss, be simultaneously introduced sodium silicate and can reinforce the strong of motar with calcium chloride Degree, improves the bearing capacity of motar;Add quick lime motar can be made to be not easy hardened with the moisture absorption, add antibacterial Make the storage of motar more permanent.Dry-mix proposed by the present invention has good water-retaining property, workability, anti-current Extension property, stronger cohesive force, mechanical property and storage, durability, and take full advantage of the garbage after phosphate ore processing, solution Determine the flyash producing after coal combustion, be conducive to resource environment protection, meet social orientation.Its additive amount is few, price Low, pollution-free, storage is convenient, easy to use.
