Embodiment 1

[0022] (1) Mix 20 parts of No. 425 cement, 58.8 parts of 40-mesh quartz sand, 20 parts of low-temperature elastic VAE emulsion, 0.5 part of hydroxypropyl methylcellulose, 0.2 part of early strength agent, and 0.5 part of 1mm polypropylene bundle fiber Evenly, add 24 parts of water to adjust to a slurry suitable for batch scraping.

[0023] (2) Lay a layer of mortar cloth, lay a layer of glass fiber mesh cloth of the same size on the back of the mortar cloth, apply 0.6kg / ㎡ composite slurry, and press or roll the glass fiber mesh cloth until it sinks into the composite In the slurry, the bottom tire composed of mortar cloth and glass fiber mesh can be obtained after natural curing for 3-7 days.

Embodiment 2

[0025] (1) Mix 25 parts of No. 325 cement, 70 parts of 40-mesh quartz sand, 5 parts of alkali-resistant acrylic emulsion, 0.1 part of hydroxypropyl methylcellulose, 0.05 part of early strength agent, and 0.3 part of wood fiber. Mix one portion to a slurry suitable for batch scraping for later use.

[0026] (2) Lay a layer of mortar cloth, lay a layer of synthetic fiber non-woven fabric of the same size on the back of the mortar cloth, apply 0.6kg / ㎡ composite slurry, and rub or roll the synthetic fiber non-woven fabric until it sinks into the composite In the slurry, apply a layer of composite slurry, the dosage is 1.0kg / ㎡, and press or roll until the synthetic fiber non-woven fabric is soaked and covered by the composite slurry, and the mortar cloth and synthetic fiber can be obtained after natural curing for 3-7 days. Fiber non-woven composite bottom tire.

Embodiment 3

[0028] (1) 30 parts of No. 425 cement, 60 parts of 40-mesh quartz sand, 9 parts of alkali-resistant acrylic emulsion, 0.4 part of hydroxypropyl methylcellulose, 0.1 part of early strength agent, 0.2 part of 10mm polypropylene bundle fiber, wood 0.3 parts of fiber are mixed and stirred evenly, and 18 parts of water are added to adjust to a slurry suitable for batch scraping.

[0029] (2) Lay a layer of mortar cloth, lay a layer of glass fiber mesh cloth of the same size on the back of the mortar cloth, apply 0.6kg / ㎡ composite slurry, and press or roll the glass fiber mesh cloth until it sinks into the composite In the slurry, repeat this step on this basis, and then add 1-2 pieces of glass fiber mesh cloth, the amount of composite mortar for each piece of glass fiber mesh cloth is 1.2kg / ㎡, natural curing for 3-7 days That is to obtain the base tire compounded with mortar cloth and glass fiber mesh.

Abstract

The invention discloses a bottom tire composed of mortar cloth and anti-cracking fiber net. The preparation method is: (1) mix the raw materials that make up the composite slurry according to the proportion, stir evenly, and obtain the composite slurry for use; (2) apply a layer of composite slurry on a layer of mortar cloth, and spread a layer of anti-corrosion mortar of the same size. Crack fiber mesh, press or roll until the anti-crack fiber mesh is immersed in the composite slurry, and then apply a layer of composite slurry and press or roll until the anti-crack fiber mesh is soaked and covered by the composite slurry, or On this basis, repeat the above steps, add 1-2 sheets of anti-cracking fiber mesh cloth, and naturally maintain for 3-7 days to obtain the base tire composited with mortar cloth and anti-cracking fiber mesh; in the (2) step, Each layer of anti-cracking fiber net is bonded and covered with 0.5-1.5kg / ㎡ composite slurry and mortar cloth. The invention has the advantages of softness, lightness, crack resistance, bending resistance, aging resistance, environmental protection, durability, etc., and is soft but not rigid, and the manufacturing procedure is simplified, the manufacturing cost is reduced, and the construction is simple.

Description

technical field [0001] The invention relates to a base tire compounded with mortar cloth and crack-resistant fiber net, which belongs to the field of new building decoration materials. Background technique [0002] With the country's increasing enforcement of building energy conservation, and the safety requirements for high-rise buildings with more than 20 floors, or public facilities with a height of more than 60 meters near streets, roads, schools, hospitals, large shops, cultural and sports venues, etc. With the improvement of strength, traditional exterior wall bricks are no longer commonly used. With the development of social economy, rising prices, and rising construction costs, various technicians in the construction industry have been researching building decoration materials with lower production costs, lower construction costs, higher performance, and safer. Therefore, exterior walls Decorative panels emerged as the times require, and are highly recognized by the...
