Embodiment 1

[0019] A method for preparing wet-mixed mortar that is not prone to precipitation, comprising the steps of:

[0020] S1. Mix 20g of epoxy tall oil and 6g of acrylic acid evenly, and use a plasma generator to irradiate for 30min with a radiation power of 800W, wherein the plasma generator is 2mm away from the liquid surface to obtain the first prefabricated material;

[0021] S2. Mix 3g of calcium lignosulfonate, 1g of water repellent, 3g of sepiolite powder, 1g of sodium alginate, 2g of diatomaceous earth, and 1g of the first preform to obtain a second preform;

[0022] S3. Mix 50g of cement, 4g of cinder, 6g of mineral powder, 50g of river sand, and 50g of water evenly, add 1g of the second prefabricated material and continue stirring for 40min at a stirring speed of 300r / min to obtain a wet-mixed mortar that is not prone to precipitation.

Embodiment 2

[0024] A method for preparing wet-mixed mortar that is not prone to precipitation, comprising the steps of:

[0025] S1. Mix 40g of epoxy tall oil and 1g of acrylic acid evenly, and use a plasma generator to irradiate for 50 minutes with a radiation power of 400W, wherein the plasma generator is 5mm away from the liquid surface to obtain the first prefabricated material;

[0026] S2. Mix 1g of calcium lignosulfonate, 2g of water repellent, 1g of sepiolite powder, 2g of sodium alginate, 1g of diatomaceous earth, and 3g of the first preform to obtain a second preform;

[0027] S3. Mix 30g of cement, 15g of coal cinder, 2g of mineral powder, 100g of river sand, and 30g of water evenly, add 3g of the second prefabricated material and continue stirring for 20 minutes at a stirring speed of 400r / min to obtain a wet-mixed mortar that is not prone to precipitation.

Embodiment 3

[0029] A method for preparing wet-mixed mortar that is not prone to precipitation, comprising the steps of:

[0030] S1. Mix 25g epoxy tall oil and 4g acrylic acid evenly, and use a plasma generator to irradiate for 35 minutes, with a radiation power of 700W, wherein the plasma generator is 3mm away from the liquid surface, to obtain the first prefabricated material;

[0031] S2. Mix 2.5g calcium lignosulfonate, 1.2g water-repellent, 2.5g sepiolite powder, 1.2g sodium alginate, 1.7g diatomaceous earth, and 1.5g first preform to obtain a second preform;

[0032] S3. Mix 45g of cement, 8g of cinder, 5g of mineral powder, 60g of river sand, and 45g of water evenly, add 1.5g of the second prefabricated material and continue stirring for 35min at a stirring speed of 330r / min to obtain a wet-mixed mortar that is not prone to precipitation.

Abstract

The invention discloses a preparation method of wet-mixed mortar not prone to precipitation. The method includes the steps that epoxy tall oil and acrylic acid are evenly mixed, and a plasma generatoris adopted for radiation to obtain a first preformed material; calcium lignosulphonate, a water repellent, sepiolite powder, sodium alginate, diatomite and the first preformed material are evenly mixed to obtain a second preformed material; cement, coal cinder, mineral powder, river sand and water are evenly mixed, the second preformed material is added, and stirring continues to obtain the wet-mixed mortar not prone to precipitation. By means of the method, the water retentivity of the wet-mixed mortar can be improved, the consistence of the obtained wet-mixed mortar can be kept stable within a certain time, the operable time can reach 20 h, and the obtained wet-mixed mortar is suitable for mortar machine spraying work, has the advantages of improving working efficiency, reducing labor cost and machine cost and relieving labor intensity of workers, and has great application and promotion value.

Description

technical field [0001] The invention relates to the technical field of wet-mixed mortar, in particular to a preparation method of wet-mixed mortar which is not prone to precipitation. Background technique [0002] Wet-mixed mortar can reduce the secondary dust pollution caused by on-site mixing and stacking of powdery and granular building materials in the open air, and prevent the waste of a large amount of building materials such as cement and yellow sand from turning into mud and sand in the rainy season, flowing into urban sewage pipes, causing blockage, and affecting the living environment and environment. Urban Environmental Governance. The use of wet-mixed mortar can not only effectively protect the environment, reduce solid waste discharge, but also realize the recycling of resources. [0003] However, the current wet-mixed mortar is often prone to mortar sedimentation, and the pump often blocks after a period of use, which cannot meet the pumping demand of the mort...
