Embodiment 1

[0011] Example 1 A plasticizer for masonry and plastering mortar. The composition and weight ratio of the plasticizer are rosin: sodium hydroxide: polyvinyl alcohol: water = 10:1: 10:90; said rosin is a first-grade product for industrial use; sodium hydroxide is an industrial grade.

[0012] A kind of masonry provided by the invention, the preparation method of plastering mortar plasticizer is as follows:

[0013] According to the weight ratio of rosin: sodium hydroxide: water is 10:1:10, add water and sodium hydroxide into the water bath and heat to 60°C, then add rosin powder with a particle size of 1mm evenly; according to polyvinyl alcohol: The weight ratio of water is 10:80, add polyvinyl alcohol and water, until the rosin is completely dissolved and become a light yellow thick body, continue to boil for 2 hours, and condense into a dark brown paste.

[0014] Usage: (1) According to the weight ratio of plasticizer and water of 1:10, dilute the plasticizer for masonr...

Embodiment 2

[0015] Example 2 A plasticizer for masonry and plastering mortar. The composition and weight ratio of the plasticizer are rosin: sodium hydroxide: polyvinyl alcohol: water = 8:1: 12:80; said rosin is a first-grade product for industrial use; sodium hydroxide is an industrial grade.

[0016] A kind of masonry provided by the invention, the preparation method of plastering mortar plasticizer is as follows: press rosin: sodium hydroxide: the weight ratio of water is 8:1: 10, water, sodium hydroxide are added in the water-bath pot and heated to 60°C, then add rosin powder with a particle size of 1mm evenly; according to the weight ratio of polyvinyl alcohol:water of 12:70, add polyvinyl alcohol and water, until the rosin is completely dissolved and becomes a light yellow thick body, continue to boil for 2 Hours, condensed into a dark brown paste. The rest are the same as in Example 1

Embodiment 3

[0017] Example 3 A plasticizer for masonry and plastering mortar. The composition and weight ratio of the plasticizer are rosin: sodium hydroxide: polyvinyl alcohol: water = 12:1: 8:120; said rosin is a first-grade product for industrial use; sodium hydroxide is an industrial grade.

[0018] A kind of masonry provided by the invention, the preparation method of plastering mortar plasticizer is as follows: press rosin: sodium hydroxide: the weight ratio of water is 12:1: 15, water, sodium hydroxide are added in the water bath pot and are heated to 60°C, then add rosin powder with a particle size of 1mm evenly; according to the weight ratio of polyvinyl alcohol:water of 8:105, add polyvinyl alcohol and water, until the rosin is completely dissolved and becomes a light yellow thick body, continue to boil for 2 Hours, condensed into a dark brown paste. The rest are the same as in Example 1

Abstract

The invention provides masonry, a plastering mortar plasticizer and a preparation method. The plastering mortar plasticizer comprises the components in the weight ratio of rosin to sodium hydroxide to polyvinyl alcohol to water of (8-12):1:(8-12):(80-120). The formula of the plastering mortar plasticizer is scientific and reasonable, the preparation method is simple, and cost is low. By adopting the plastering mortar plasticizer provided by the invention, numerous small bubbles can be produced in mortar, volume of cement can be increased, a friction force among sand grains is reduced, performance of cement mortar can be improved, peaceability and water-retaining property of mortar are enhanced; meanwhile, construction and plastering effects of the mortar are improved; ash fallen to ground is also reduced; cement is saved, no lime paste is used, and the environment is protected; besides, the effects of diffusing the cement, emulsifying and foaming can be achieved; common problems of flaking and cracking are solved; and good effect also can be achieved when the plastering mortar plasticizer provided by the invention is used for bottoming of bottom surface of aerated concrete and common concrete or is used on the surface layer of the aerated concrete and the common concrete. Detection is carried out on building mortar added with the plastering mortar plasticizer provided by the invention according to the Chinese National Standard, and results show that the plastering mortar plasticizer provided by the invention is completely in conformity with the Chinese National Standard.

Description

technical field [0001] The invention relates to a masonry and plastering mortar plasticizer and a preparation method, belonging to the field of construction. Background technique [0002] Traditional construction mortar is generally mixed on site, and has poor construction workability, low cohesive force, large shrinkage, and poor durability. It is easy to crack, leak, hollow, and fall off when used in the construction of interior and exterior walls. Especially will add a large amount of lime, not only increases labor cost but also pollutes the environment. Later, plasticizers were widely used. But lime paste or lime powder is also used. There is still the problem of polluting the environment, and the cost is relatively high, which is not accepted by the construction unit. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention provides a masonry and plastering mortar plasticizer and a preparation method. Provide a new ...
