Putty powder preparation method

Abstract

The invention belongs to the technical field of building materials, and particularly relates to a putty powder preparation method. The putty powder preparation method comprises the following steps that S1, raw materials are crushed, specifically, a base material, filler and an auxiliary are mixed and then crushed, so that the raw materials are in a small block shape; S2, the raw materials are ground, specifically, the small-block-shaped raw materials prepared in step 1 are ground, and thus the powdery raw materials are obtained; and S3, the raw materials are screened, specifically, the powderyraw materials prepared in step 2 are screened and then subpackaged, and the process of screening the powdery raw materials in step 3 is completed through the cooperation of a putty powder preparationmachine. According to the putty powder preparation method, fine materials and coarse materials are collected synchronously while the powdery raw materials are screened, the processing efficiency is improved, a screen plate does not need to be dismounted during collection, and the operation is convenient; and when the raw material powder particles of putty powder are screened, the fine materials clamped in screen holes of the strip-shaped screen plate can be vibrated off, and thus the blockage of the screen holes is avoided.

Description

technical field [0001] The invention belongs to the technical field of putty powder, and in particular relates to a preparation method of putty powder. Background technique [0002] Putty powder is a kind of building decoration material. Putty powder is composed of base material, filler and auxiliary agent. The base material, also known as the binder, is the most critical component of the putty powder. It mainly plays various roles such as bonding. The most commonly used binders are cement and organic polymers. Fillers mainly play a filling role, commonly used are calcium carbonate, talcum powder and quartz sand. Auxiliaries include thickeners, water retaining agents and antifreeze agents. Thickener and water retaining agent play the role of water retention, improving storage and construction performance; antifreeze mainly improves the storage stability of putty powder at low temperature. Putty powder needs to be prepared by first breaking the raw materials into small pie...

Problems solved by technology

[0004] The invention provides a method for preparing putty powder, and the purpose is to solve the following problems existing in the preparation of putty powder at present: (1) when sieving raw material powder particles, it is impossible to screen the fine material and The coarse material on the sieve plate is collected synchronously, and the sieve plate can only be removed for collection after the sieving is completed, the processing efficiency is low and the operation is inconvenient; (2) when the raw material powder is sieved through the sieve plate, the In the process of passing through the sieve holes on the sieve plate, it is easy to get stuck inside the sieve holes and form a blockage, which reduces the efficiency of screening
