Description

Technical Field

[0001] The invention discloses a lightweight anti-cracking plastering mortar for interior and exterior walls and a preparation method thereof, belonging to the field of anti-cracking plastering mortar preparation. Background Art

[0002] All mortars applied to the surface of buildings or building components are collectively referred to as plastering mortars. Depending on their functions, plastering mortars can be divided into ordinary plastering mortars, decorative mortars, and plastering mortars with certain special functions (such as waterproof mortars, thermal insulation mortars, sound-absorbing mortars, and acid-resistant mortars).

[0003] The existing plastering mortar with anti-cracking function requires the addition of an anti-cracking agent during the preparation process. The main component of the anti-cracking agent is an organic polymer mixed emulsion. The organic polymer mixed emulsion is easily affected by the environment and solidifies into blocks. When it is directly introduced into the plastering mortar raw materials in the mixing process, it is easy to fail to fully mix with the plastering mortar raw materials, thereby affecting the anti-cracking effect. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a lightweight anti-cracking plastering mortar for interior and exterior walls and a preparation method thereof, so as to solve the problem that the existing plastering mortar with anti-cracking function needs to add an anti-cracking agent during the preparation process, and the main component of the anti-cracking agent is an organic polymer mixed emulsion. The organic polymer mixed emulsion is easily affected by the environment and solidified into blocks. When it is directly introduced into the plastering mortar raw materials in the mixing process, it is easy to fail to fully mix with the plastering mortar raw materials, thereby affecting the anti-cracking effect.

[0005] In order to achieve the above-mentioned object, the present invention is realized through the following technical solutions: a method for preparing lightweight anti-cracking plastering mortar for interior and exterior walls, in which a special fully mixed material guiding structure is adopted for mixing work. The special fully mixed material guiding structure comprises a frame, a hopper is provided on the inner side of the top of the frame, a positioning seat is provided at the discharge port of the bottom of the hopper, an outer wall of one side of the hopper is provided with a driving seat connected with the positioning seat, a pushing channel is horizontally provided in the middle of the driving seat, the pushing channel passes through the positioning seat and communicates with the hopper, the inner side of the positioning seat is inclined downward and is provided with a guiding plate covering the outlet of the pushing channel, a charging trough connected with the pushing channel is provided on the top of the driving seat, a heating plate is provided on the inner wall of the pushing channel, a heater connected with the heating plate is provided in the bottom of the driving seat, an electric pushing cylinder is provided on the outer side of the driving seat, the output end of the electric pushing cylinder is movably fitted into the pushing channel, and a control panel for controlling the operation of the heater and the electric pushing cylinder is provided on the bottom surface of the driving seat;

[0006] A method for preparing lightweight anti-cracking plastering mortar for interior and exterior walls using a dedicated fully mixed material guiding structure comprises the following steps:

[0007] Step S1, introducing the raw material of lightweight anti-cracking plaster mortar particles for interior and exterior walls into a stirring and mixing device through a hopper, and stirring and mixing;

[0008] Step S2 also includes 100-120 mesh quartz sand blocks. During the stirring and mixing process, ten portions of 100-120 mesh quartz sand blocks pressed into blocks are placed into the pushing channel through the loading trough. The heater outputs heat to the heating plate. The heating plate heats the 100-120 mesh quartz sand blocks. An assembly groove is provided on the top of the 100-120 mesh quartz sand block. A 100-120 mesh quartz sand cover is embedded in the assembly groove. A spherical fiber membrane is provided in the assembly groove. The spherical fiber membrane is filled with an organic polymer mixed emulsion. Heat is transferred to the assembly groove, and the spherical fiber membrane and the organic polymer mixed emulsion are heated, effectively preventing agglomeration.

[0009] Step S3, after heating for ten seconds, the electric pushing cylinder pushes the 100-120 mesh quartz sand block out of the pushing channel, and it falls into the stirring and mixing equipment from the bottom of the hopper. The organic polymer mixed emulsion in the spherical fiber membrane passes through this process to break the spherical fiber membrane. With the action of the stirring and mixing equipment, the 100-120 mesh quartz sand block is crushed and quickly mixed with the spherical fiber membrane and the organic polymer mixed emulsion in the lightweight anti-cracking plaster mortar particle raw material for the interior and exterior walls, thereby improving the anti-cracking agent formed by the organic polymer mixed emulsion and fully mixing with the raw materials.

[0010] Furthermore, the raw materials for lightweight anti-cracking plaster mortar particles for interior and exterior walls are mixed according to the weight ratio: 1 to 2 parts of cellulose fiber, 100 to 105 parts of 100-120 mesh quartz sand, 8 to 9 parts of thickening powder, 26 to 30 parts of redispersible latex powder, 400 to 420 parts of cement, and 20 to 30 parts of lime.

[0011] Furthermore, the length, width and height of the assembly groove are 5-10 cm, 5-10 cm and 10-15 cm respectively.

[0012] Furthermore, the positioning seat and the hopper are an integrated structure.

[0013] Furthermore, the outlet of the pushing channel has a slope.

[0014] The beneficial effects of the present invention are as follows: a portion of sand is pressed into blocks in advance, and an organic polymer mixed emulsion wrapped by a spherical fiber membrane is placed in the sand blocks, which are then introduced into a stirring device through a heated hopper. The sand blocks with residual temperature will not cause the organic polymer mixed emulsion to form agglomerates, and under the action of the stirring device, the sand blocks are crushed, and the organic polymer mixed emulsion is directly mixed into the raw materials, enabling sufficient mixing.
