Embodiment 1

[0025] A highly adaptable wet-mix mortar additive, including the following raw materials in parts by weight: 13 parts of thickener, 7 parts of air-entraining agent, 15 parts of water reducing agent, 12 parts of water-retaining agent, 11 parts of retarder, anti-cracking agent 9 parts, 5 parts of foam stabilizer and 75 parts of water.

[0026] In this example, the thickening agent is maltose beerugin, the air-entraining agent is a mixture of sodium abietate, triterpene saponin and sodium lauryl sulfate, the water-reducing agent is prenol polyoxyethylene ether, and the water-retaining agent is hydroxy Composition of propyl methylcellulose and Wenlun glue, and the amount of hydroxypropyl methylcellulose is 10% of the amount of Wenlun glue, and the retarder is a composition of sodium citrate and sodium hexametaphosphate, anti-cracking The agent is hydroxypropyl methylcellulose, and the foam stabilizer is fatty acyldiethanolamine.

[0027] On the other hand, the present invention a...

Embodiment 2

[0033] A highly adaptable wet-mix mortar additive, including the following raw materials in parts by weight: 12 parts of thickener, 8 parts of air-entraining agent, 15 parts of water-reducing agent, 10 parts of water-retaining agent, 13 parts of retarder, anti-cracking agent 10 parts, 4 parts of foam stabilizer and 80 parts of water.

[0034] In this example, the thickener is polyacrylamide, the air-entraining agent is a mixture of sodium abietate, triterpene saponin and sodium lauryl sulfate, the water-reducing agent is an aliphatic water-reducing agent, and the water-retaining agent is hydroxypropylmethyl The combination of base cellulose and Wenlun glue, and the amount of hydroxypropyl methylcellulose is 10% of the amount of Wenlun glue, the retarder is sodium gluconate, white sugar composition, and the anti-cracking agent is hydroxypropylmethyl Cellulose and sodium alginate are mixed at a ratio of 1:1, and the foam stabilizer is fatty acyldiethanolamine.

[0035] On the o...

Embodiment 3

[0041] A highly adaptable wet-mix mortar additive, including the following raw materials in parts by weight: 15 parts of thickener, 5 parts of air-entraining agent, 13 parts of water-reducing agent, 12 parts of water-retaining agent, 15 parts of retarder, anti-cracking agent 13 parts, 6 parts of foam stabilizer and 90 parts of water.

[0042] In this example, the thickener is polyacrylamide, the air-entraining agent is a mixture of sodium abietate, triterpene saponin and sodium lauryl sulfate, the water reducing agent is a naphthalene-based superplasticizer, and the water-retaining agent is hydroxypropyl The composition of methyl cellulose and Wenlun glue, and the consumption of hydroxypropyl methylcellulose is 15% of the consumption of Wenlun glue, the retarder is sodium gluconate, and the anti-cracking agent is hydroxypropyl methylcellulose, Sodium alginate and redispersible latex powder are mixed at a ratio of 1:1:1, and the foam stabilizer is fatty acyldiethanolamine.

Abstract

The invention relates to the technical field of building materials, in particular to a high-adaptability wet-mixed mortar additive and a manufacturing process thereof, and the high-adaptability wet-mixed mortar additive is prepared from the following raw materials in parts by weight: 12-15 parts of a thickening agent, 5-8 parts of an air entraining agent, 10-15 parts of a water reducing agent, 10-12 parts of a water-retaining agent, 10-15 parts of a retarder, 8-12 parts of an anti-cracking agent, 4-6 parts of a foam stabilizer and 70-100 parts of water. The additive is reasonable in proportion, simple and convenient in preparation process, high in water retention rate and large in volume weight, the prepared additive is used in mortar to effectively improve the hardening strength of wet-mixed mortar, the adopted water-retaining agent can enable the wet-mixed mortar to still have very good water retention at high temperature, the addition amount can be increased, pumping is convenient when the additive is added into the wet-mixed mortar, the precision of the liquid mortar consistency regulator is easier to control in production, and corresponding adjustment is easier to make according to environmental factors.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a highly adaptable wet-mixed mortar additive and a manufacturing process thereof. Background technique [0002] Construction mortar includes masonry mortar and plastering mortar. According to the production method of mortar, ready-mixed mortar can be divided into two categories: wet-mixed mortar and dry-mixed mortar. Among them, the wet-mixed mortar is composed of cement, mineral admixture, fine aggregate, admixture, water and various components determined according to the construction performance. According to the different grades of the mortar, according to a certain proportion, it is measured and mixed in the mixing station. Finally, it is transported to the place of use by a mixer truck, stored in a special container pool, and the mixture is used within the specified time. Wet-mixed mortar is transported from the production point to on-site use, and the requiremen...
