preparation example Construction

[0021] The preparation method comprises the following steps:

[0022] Step a, weighing raw materials methyl ethyl cellulose ether, methyl hydroxypropyl cellulose ether, starch ether, acrylic acid rubber powder, triterpene saponin according to the proportioning ratio;

[0023] Step b, putting the raw materials proportioned in step 1 into a conical double-helix mixer and stirring evenly for 8-15 minutes to obtain a stirred mixture;

[0024] In step c, add AC foaming agent to the mixture stirred in step b, and then return to the machine and stir for 8-15 minutes to obtain mortar glue.

[0025] The usage method of described mortar glue is: every 50kg cement mixes 5-15g mortar glue, adopts mechanical stirring mortar;

[0026] The mixing process of the vertical mixer or horizontal mixer: start the machine, put in part of the sand, mortar glue, water and fully stir, then put in the cement and all the sand, and continue to stir for 3-5 minutes;

[0027] The mixing process of the dru...

Abstract

The invention provides a mortar glue. Raw materials of the mortar glue comprise, by weight, 15-30 parts of methylethyl cellulose ether, 20-45 parts of methylhydroxypropyl cellulose ether, 1-5 parts of an AC foaming agent, 10-28 parts of starch ether, 20-30 parts of acrylic glue powder and 8-12 parts of triterpenoid saponins. A weight ratio of the methylethyl cellulose ether to the methylhydroxypropyl cellulose ether is 2:3, so the requirement glue of the mortar glue for the water: cement: sand ratio is reduced.

Description

technical field [0001] The technical field of building materials of the present invention particularly relates to a mortar glue and a preparation method thereof. Background technique [0002] Cement mortar is the most commonly used building material in construction engineering, and it occupies a large proportion in building materials, and is one of the indispensable building materials. [0003] Chinese invention patent (Patent No. 200610009998.7) discloses a building mortar cementitious material, which is composed of 60-70% by weight of fly ash, 25-35% of cement clinker and 4-6% of additives. The weight percentage composition is 15-25% of hydroxymethyl cellulose, 10-20% of triterpene saponins, 30-40% of calcium lignosulfonate, 15-25% of methylphenylhydrazine hydrochloride and 7-13% of phosphate . The building mortar cementitious material is used in the mortar of masonry and interior wall plastering in industrial and civil buildings. [0004] However, when paving, the abov...
