Embodiment 1

[0021] In the embodiment of the present invention, a construction mortar is composed of the following raw materials according to parts by weight: 8 parts of Longzi, 1 part of Uncaria, 22 parts of quartz sand, 6 parts of talcum powder, 65 parts of calcium sulfate, lignin sulfonate Salt 2 parts.

[0022] After washing Longzi and Uncaria with water to remove impurities, add absolute ethanol three times the mass of the two, stir at a temperature of 58°C until the absolute ethanol evaporates to dryness, and then add acetic acid equal to the mass of the two, Stir at a temperature of 50°C until the acetic acid is evaporated to dryness; then freeze-dry the acetic acid-treated Longzi and Uncaria at a temperature of -40°C and a vacuum of 25Pa, and freeze-dry the dried Longzi, Uncaria is ground, passed through a 40-mesh sieve, and then ultrafinely pulverized at -10°C for 10 minutes to obtain pretreated dragon fruit and uncaria. Dry the quartz sand until the moisture content is below 0.3...

Embodiment 2

[0024] In the embodiment of the present invention, a construction mortar is composed of the following raw materials in parts by weight: 15 parts of Longzi, 5 parts of Uncaria, 28 parts of quartz sand, 10 parts of talcum powder, 73 parts of calcium sulfate, lignin sulfonate Salt 5 parts.

[0025] After washing Longzi and Uncaria with water to remove impurities, add absolute ethanol 4 times the mass of the two, stir at 62°C until the absolute ethanol evaporates to dryness, then add acetic acid twice the mass of the two, Stir at a temperature of 53°C until the acetic acid is evaporated to dryness; then freeze-dry the acetic acid-treated Longzi and Uncaria at a temperature of -38°C and a vacuum of 30Pa, and freeze-dry the dried Longzi, Uncaria is ground, passed through a 60-mesh sieve, and then ultrafinely pulverized at -10°C for 12 minutes to obtain pretreated Longzi and Uncaria. Dry the quartz sand until the moisture content is below 0.3%, crush it, and pass through a 100-mesh ...

Embodiment 3

[0027] In the embodiment of the present invention, a construction mortar is composed of the following raw materials in parts by weight: 10 parts of dragon fruit, 2 parts of uncaria, 24 parts of quartz sand, 7 parts of talcum powder, 67 parts of calcium sulfate, lignin sulfonate Salt 3 parts.

[0028] After washing Longzi and Uncaria with water to remove impurities, add 3.5 times the mass of absolute ethanol, stir at 60°C until the absolute alcohol is evaporated to dryness, and then add 1.5 times the mass of acetic acid, Stir at a temperature of 52°C until the acetic acid is evaporated to dryness; then freeze-dry the acetic acid-treated Longzi and Uncaria at a temperature of -39°C and a vacuum of 28Pa, and freeze-dry the dried Longzi, Uncaria is ground, passed through a 60-mesh sieve, and then ultra-finely pulverized at -10°C for 11 minutes to obtain pretreated dragon fruit and uncaria. Dry the quartz sand until the moisture content is below 0.3%, crush it, and pass through a ...

Abstract

The invention discloses building mortar and a preparation method and construction application thereof. The building mortar is prepared from, by weight, 8-15 parts of bauhinia seeds, 1-5 parts of uncaria rhynchophylla, 22-28 parts of quartz sand, 6-10 parts of talcum powder, 65-73 parts of calcium sulfate and 2-5 parts of lignosulfonate. According to the preparation method, the bauhinia seeds and the uncaria rhynchophylla are dried by distillation with absolute ethyl alcohol and acetic acid in sequence; then, freeze drying, grinding and superfine grinding are conducted, and the pretreated bauhinia seeds and uncaria rhynchophylla are obtained; the quartz sand is dried, crushed and sieved; the pretreated bauhinia seeds and uncaria rhynchophylla, the talcum powder and the lignosulfonate are added to the calcium sulfate, the mixture is stirred to be uniform, then the mixture is stirred with the sieved quartz sand to be uniform, and the building mortar is obtained. The building mortar has the functions of automatically adjusting indoor temperature and humidity, resisting to bacteria, purifying air and the like, can generate a great number of anions, is wide in application and used for decoration of offices and household indoor walls and can also be processed into ceiling decorative plates, wall decorative plates and the like.

Description

technical field [0001] The invention relates to the field of ready-mixed mortar, in particular to a building mortar and its preparation method and construction application. Background technique [0002] Ready-mixed mortar refers to various mortar mixtures produced by specialized manufacturers and used in construction projects. It is a new type of building material developed in my country in recent years. It can be divided into ordinary ready-mixed mortar and special mortar according to its performance. Ordinary mortar mainly includes masonry mortar, plastering mortar and ground mortar. Masonry mortar and plastering mortar are mainly used for masonry and plastering of various concrete bricks, fly ash bricks and clay bricks in load-bearing walls and non-load-bearing walls. Ground mortar is used for ground leveling in ordinary and special occasions. Special mortar includes thermal insulation mortar, decorative mortar, self-leveling mortar, waterproof mortar, etc. It has variou...
