Abstract

The invention provides a mortar additive, a mortar additive preparation method and a method for preparing mortar with the mortar additive.The mortar additive is composed of organic silicon type water repellents, redispersible latex powder, hydroxypropyl methyl cellulose ether, polycarboxylic type water reducer, modified starch ether, polypropylene fibers and fillers according to a weight ratio of 0.8-1.2:0.8-1.2:0.6-0.8:0.3-0.58:0.1-0.13:0.3-0.58:0.1-0.3.Compared with a common additive, the mortar additive has the advantages that reaction is quicker and more complete, strength increase is quicker and higher, abrasion resistance, durability, cracking resistance and seepage proofing performances of concrete can be evidently improved, functions of water reduction, early strengthening and air entrainment are realized, and the mortar additive is higher in adaptability to various concretes and extensive in application prospect.

Description

technical field [0001] The product of the present invention is developed for the current and future waterproofing of building exterior walls and bathroom interior walls. It is easy to use and can be constructed after adding and stirring according to the weight of cement. Background technique [0002] Today, there are two methods for waterproofing the exterior walls of buildings: 1. Use polymer waterproof coatings to apply a certain thickness to achieve waterproofing. 2. Use polymer waterproof mortar to apply a certain thickness to achieve waterproof effect. 3. Polymer waterproof coating: within the validity period, the waterproof effect is very good. Its main ingredients: emulsion (pure acrylic, styrene acrylic) additives, cement. Among them, the emulsion is organic, and its effective life is generally 3-5 years. After the effective life, the material will be pulverized and has no waterproof effect, and it will cause the outer layer of tiles to fall off or the hollowing an...
