Embodiment 1

[0031] In parts by weight, weigh 1 part of water-soluble polyether polyurethane, 1 part of hydroxyethyl methylcellulose ether, and 1 part of methyl methacrylate-butadiene-styrene polymer, and use a Dissolve warm water in the reaction vessel, stir for 20 minutes, and keep stirring. Add 63 parts of machine-made sand, 7 parts of molybdenum tailings sand, 20 parts of 100-mesh beer bottle fine powder, stir evenly for 20 minutes, and then add 70 parts of cement with a molecular weight of 30000 and MPEG-AMPS shrinkage-reducing polycarboxylate water reducer with a block ratio of polyethylene glycol monomethyl ether and 2-acrylamido-2-methylpropanesulfonic acid of 4:1, stirred for 15 minutes to obtain the Dry powder grouting material for prefabricated components.

Embodiment 2

[0033] In parts by weight, weigh 2 parts of water-soluble polyester polyurethane, 2 parts of hydroxypropyl methylcellulose ether, and 2 parts of acrylonitrile-butadiene-styrene polymer, and dissolve them in warm water with a temperature of 30°C. In the reaction vessel, stir for 15 minutes, keep stirring, add 68 parts of machine-made sand, 12 parts of molybdenum tailings sand, 25 parts of 150-mesh waste glass fine powder, stir evenly for 25 minutes, then add 80 parts of cement with a molecular weight of 40000 and vinyl The APEG-MAA shrinkage-reducing polycarboxylate superplasticizer with a block ratio of propyl polyoxyethylene ether to methacrylic acid of 5:1 was stirred for 15 minutes to obtain the dry powder grouting material for the prefabricated component steel sleeve.

Embodiment 3

[0035] In parts by weight, weigh 2 parts of water-soluble polyester polyurethane, 2 parts of hydroxypropyl methylcellulose ether, and 2 parts of acrylonitrile-butadiene-styrene polymer, and dissolve them in warm water with a temperature of 25°C. In the reaction vessel, stir for 20 minutes, keep stirring, add 68 parts of machine-made sand, 12 parts of molybdenum tailings sand, 25 parts of 150 mesh waste glass ground powder in a small amount and multiple times, stir evenly for 20 minutes, then add 80 parts of cement, the molecular weight is 50000 and Allyl polyoxyethylene ether and methacrylamide block ratio of TPEG-MA shrinkage polycarboxylate superplasticizer of 5:1, stirred for 20 minutes, to obtain the prefabricated component steel sleeve dry powder grouting material.

Abstract

The invention belongs to the field of prefabricated component building materials, and in particular relates to a steel bar sleeve grouting material for prefabricated components and a preparation method thereof. The steel sleeve grouting material for prefabricated components includes the following components: 70-100 parts by weight of cement, 75-100 parts by weight of mixed sand, 20-30 parts by weight of glass powder, 1-3 parts by weight of expansion agent, and 1-3 parts by weight of thickener. 3 parts by weight, 1-5 parts by weight of polycarboxylate water-reducer, and 1-3 parts by weight of toughening agent; the polycarboxylate water-reducer is a modified polyether polymer; the expansion agent is water-soluble polyurethane. The invention adopts water-soluble polyurethane as the expansion agent, which has dual performances of elastic water stop and water stop, and can change the expansion rate by adjusting the water consumption to meet the different requirements of early expansion and later expansion; Carboxylic acid superplasticizer can achieve the purpose of reducing shrinkage in the presence of cement, mixed sand and glass powder; adding toughening agent can be used to deal with existing expansion joints and live joints, and the construction performance is good.

Description

technical field [0001] The invention belongs to the field of prefabricated component building materials, and in particular relates to a reinforcement sleeve grouting material for prefabricated components and a preparation method thereof. Background technique [0002] As the concept of green environmental protection is becoming more and more popular, for the construction industry, the application of green building materials and green buildings is becoming more and more extensive. As the main means of building green development, the steel sleeve grouting connection technology is involved in various fields such as industrial and civil construction, road bridges, underground engineering, ocean engineering, and nuclear power engineering. The grouting connection technology adopts the method of factory prefabricated components and on-site connection, which not only reduces the cumbersome construction procedures, but also saves energy, reduces emissions, and protects the environment...
