preparation example Construction

[0044] The preparation method of quick-drying putty paste specifically comprises the steps:

[0045] (1) In a state of stirring, add a thickener to the water and mix well;

[0046] (2) Add dispersant, wetting agent, film-forming aid, preservative, emulsion and thixotropic agent successively to step (1) gained mixture and mix uniformly;

[0047] (3) Add defoamer to the mixture obtained in step (2) and mix evenly without bubbles;

[0048] (4) Add 325 mesh heavy calcium carbonate, 800 mesh heavy calcium carbonate, and 1250 mesh heavy calcium carbonate to the mixture obtained in step (3) and mix evenly to obtain the quick-drying putty paste.

[0049] Performance testing method of quick-drying putty paste

[0050] According to the industry standard "Putty for Building Interior" JG / T 298-2010, determine the drying time, workability and bonding strength of the quick-drying putty paste; according to the industry standard "Putty for Building Exterior Wall" JG / T 157-2009, measure The...

Embodiment 1～5 and comparative example 1～4

[0053] The variables in Examples 1-5 and Comparative Examples 1-4 are the type of emulsion and the ratio relationship between water and emulsion.

[0055]

[0056] Table 1-2 Performance testing results of quick-drying putty pastes of Examples 1-5 and Comparative Examples 1-4

[0057]

[0058] From Table 1-1 and Table 1-2, it can be seen that the quick-drying putty paste of the present application not only has the advantage of short drying time, but also has the advantages of good construction, high bonding strength and good flexibility.

[0059] By comparing Examples 1 to 4 and Comparative Examples 1 to 4, it can be known that increasing the amount of emulsion increases the drying time of the quick-drying putty paste; reducing the amount of emulsion added, the indicators such as the bonding strength and flexibility of the quick-drying putt...

Embodiment 6～7 and comparative example 5～15

[0062] Embodiment 6~7 and comparative example 5~15 change the particle diameter and three kinds of particle sizes of small particle size ground calcium carbonate, medium particle size ground calcium carbonate and large particle size ground calcium carbonate on the basis of embodiment 2. The proportion of heavy calcium carbonate.

Abstract

The application relates to the technical field of decoration materials, and specifically discloses a quick-drying putty paste and a preparation method thereof. The quick-drying putty paste includes water, emulsion, 325 mesh heavy calcium calcium carbonate, 800 mesh heavy calcium calcium carbonate, 1250 mesh heavy calcium calcium carbonate, thixotropic agent, thickener, film-forming aid, dispersant, defoamer Agents, wetting agents, preservatives. The preparation method comprises: (1) adding a thickener to water and mixing uniformly; (2) adding a dispersant, a wetting agent, a film-forming aid, a preservative, an emulsion and a thixotropic agent and mixing uniformly; (3) Add defoamer and mix uniformly; (4) Add 325 mesh heavy calcium calcium carbonate, 800 mesh heavy calcium calcium carbonate, 1250 mesh heavy calcium calcium carbonate and mix uniformly to obtain the quick-drying putty paste. The quick-drying putty paste of the present application has the advantage of short drying time.

Description

technical field [0001] The present application relates to the technical field of decoration materials, more specifically, it relates to a quick-drying putty paste and a preparation method thereof. Background technique [0002] Putty is a decorative material for smoothing the surface of the wall. It is a thick paste paint and is indispensable before the wall paint is painted. Putty is applied on the primer or directly on the object to remove uneven defects on the surface of the object to be coated. [0003] The drying time of the finish putty is usually a few hours. However, when repairing at home, it is necessary to wait for the putty layer to dry before proceeding to the next layer of paint construction, which requires keeping it away from the wall for several hours. In the case of self-repairing walls, it is difficult to ensure that you do not touch the wall. Therefore, it is necessary to develop a putty with a short drying time to meet the needs of self-repairing walls...
