Problems solved by technology

[0005] Another object of the present invention is to provide a dry-mixed mortar preparation process, which can solve the problem that the lightweight aggregate in the dry-mixed mortar is easy to layer and float, the additives with a small amount are not easy to disperse and wrap the aggregate evenly, and the high-modulus fiber is extremely difficult in the dry powder. Easy to form agglomerates and not easy to disperse, so that the material can be mixed evenly and the fibers can be dispersed

Embodiment 1

[0027] by 1m 3 To calculate the finished product, weigh 120 kg of expanded vitrified microbeads, 160 kg of 42.5 grade cement, 3 kg of wood fiber, 1 kg of hydroxypropyl methylcellulose, 6 kg of redispersible rubber powder and 0.5 kg of polypropylene short fiber.

[0028] When mixing with figure 1 For the mixing equipment shown, 160 kg of 42.5 grade cement, 3 kg of wood fiber, 1 kg of hydroxypropyl methyl cellulose, 6 kg of redispersible rubber powder and 0.5 kg of polypropylene short fiber are lifted to the storage through the feeding part 10. In the silo 21, open the outlet of the storage silo 21 so that the material is injected into the closed mixing chamber 22, and the horizontally designed spiral agitator 24 in the closed mixing chamber 22 is rotated and stirred to realize the material in the closed material convection mixing area. Mixing is completed within 5 minutes, and the mixing time is 5 minutes; when other raw materials other than the expanded vitrified microspheres...

Embodiment 2

[0030] by 1m 3 To calculate the finished product, weigh 110kg of expanded vitrified microbeads, 160kg of grade 42.5 cement, 3.5 kg of wood fiber, 1 kg of hydroxypropyl methylcellulose, 5 kg of redispersible rubber powder and 0.5 kg of polypropylene short fiber.

[0031] The mixing process was the same as in Example 1, except that the mixing time for other raw materials other than the expanded vitrified microbeads was 5 minutes, and the continuous mixing time after adding the expanded vitrified microbeads was 50 seconds, and the rest of the work will not be repeated here.

Embodiment 3

[0033] by 1m 3 To calculate the finished product, weigh 115 kg of expanded vitrified microbeads, 150 kg of 42.5 grade cement, 3.5 kg of wood fiber, 1.5 kg of hydroxypropyl methylcellulose, 6 kg of redispersible rubber powder and 0.5 kg of polypropylene short fiber.

[0034] The mixing process was the same as in Example 1, except that the mixing time for other raw materials other than the expanded vitrified microbeads was 4 minutes, and the continuous mixing time after adding the expanded vitrified microbeads was 60 seconds, and the rest of the work will not be repeated here.

Abstract

The invention relates to the technical field of building materials, in particular to dry-mixed mortar with a heat insulation function and a preparation process thereof. The dry-mixed mortar comprises the following components: expanded and vitrified small balls, cement and addictive, wherein the proportion ratio of the components is as follows by finished products / m<3>: 100-120kg of expanded and vitrified small balls, 140-160kg of cement and 10-20kg of addictive. The preparation method comprises the following steps: weighting raw materials; subsequently, mixing in a mixing device by two steps: firstly, mixing the raw materials except the expanded and vitrified small balls, and then adding the expanded and vitrified small balls to continuously mix in a closed material convective mixing region; and finally, measuring and packaging. The process of the invention is simple and can obtain the dry-mixed mortar having obvious heat insulation effect, stable structure and light quality, and the materials are evenly mixed; and the product has small coefficient of heat conductivity, superior combination property and extremely high economic benefit and society benefit, meets the new development requirements of building energy conversation, and is suitable for industrial popularization and application.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a dry-mixed mortar and a preparation process. Background technique [0002] In recent years, with the increase of building requirements from 50% to 65%, most parts of the country have started to implement it, and gradually moved towards 65% energy saving, marking that my country's construction industry has entered a new development period of building energy conservation. Wall energy saving is an important part of building energy saving. The wall has changed from a single main material type to a composite wall type, and the energy-saving wall is the main type, which has been popularized and applied throughout the country. However, the traditional mortar material can no longer meet the performance requirements of the new wall, and it can no longer be matched with the building energy-saving system. High, convenient construction, etc., the factory implements a series of ...
