Problems solved by technology

When the putty is used on the exterior wall of a building, due to the changing outdoor environment, the putty used on the exterior wall needs strong cohesive force and water resistance, which requires the putty layer itself to have a certain degree of elasticity or plasticity, so that the base layer can There will be no cracks on the building surface when there are microcracks. The main components of the existing putty powder are heavy calcium (or talcum powder), gray calcium, etc., and its anti-crack performance is not very ideal. Cracking, generally increase the amount of adhesives such as cement or rubber powder, but the effect is not ideal

Embodiment 2

[0043] Embodiment 2: The preparation method of the putty and the preparation method of the masterbatch are the same as in Example 1, but the components of the putty raw materials are respectively in parts by weight: 550 parts of base material, 230 parts of vitrified microbeads, and 50 parts of masterbatch , 550 parts of cement; the masterbatch is composed of the following raw materials in parts by weight: 25 parts of redispersible latex powder, 7 parts of hydroxypropyl methylcellulose, 0.7 part of starch ether, 1.2 parts of hydrophobic agent, and 0.7 part of water reducing agent , 2.3 parts of polypropylene staple fiber, 2.5 parts of palm fiber.

[0044] Preferably, the palm fiber is arc-shaped.

Embodiment 3

[0045] Embodiment 3: The preparation method of the putty and the preparation method of the masterbatch are the same as in Example 1, but the components of the putty raw materials are respectively in parts by weight: 400 parts of base material, 200 parts of vitrified microbeads, and 30 parts of masterbatch , 400 parts of cement; the masterbatch is made up of the following raw materials in parts by weight: each component of the masterbatch is in parts by weight: 20 parts of redispersible latex powder, 4 parts of hydroxypropyl methylcellulose, 0.5 parts of starch ether, 1 part of hydrophobic agent, 0.5 parts of water reducing agent, 2 parts of polypropylene short fiber, 2 parts of palm fiber.

[0046] Preferably, the palm fiber is arc-shaped.

[0047] In order to shape the palm fiber into an arc, a method such as Figure 2-Figure 5 A kind of external wall thermal insulation putty powder preparation equipment is shown, it comprises frame, and described frame comprises the side pl...

Abstract

The invention discloses a preparation method of exterior wall thermal insulation putty powder, which is prepared by stirring and mixing preparation raw materials consisting of base material, cement, vitrified microbeads and masterbatch. The present invention also provides a preparation equipment for external wall thermal insulation putty powder, which includes a frame, and the frame includes side plates arranged at intervals, a top plate is arranged on the top of the side plate, and the inside of the side plate is provided with a A side conveyor belt, a winding frame is placed on the side conveyor belt, and a baking area, a shaping area and a separation area are sequentially arranged on the frame along the conveying direction of the side conveyor belt from front to back; the baking area is provided with an electric heating A support is provided on the outer side of the side plate at the separation area, and a pushing device is provided on the support, and a magnetic device matching the clamping plate on the winding frame is provided on the piston rod of the pushing device. The purpose of the present invention is to improve the anti-crack property of the strong surface and at the same time improve the preparation efficiency of the putty.

Description

technical field [0001] The invention relates to the field of putty powder, in particular to a preparation method and equipment for exterior wall thermal insulation putty powder. Background technique [0002] Putty powder is a commonly used building decoration material. When the putty is used on the exterior wall of a building, due to the changing outdoor environment, the putty used on the exterior wall needs strong cohesive force and water resistance, which requires the putty layer itself to have a certain degree of elasticity or plasticity, so that the base layer can There will be no cracks on the building surface when there are micro-cracks. The main components of the existing putty powder are heavy calcium (or talcum powder), gray calcium, etc., and its anti-crack performance is not very ideal. For cracking, it is generally used to increase the amount of adhesives such as cement or rubber powder, but the effect is not ideal. [0003] At the same time, if the putty after...
