Problems solved by technology

[0003] 1. It is not easy to control the operation of adding glue to the putty powder during the construction process. When the glue is mixed for a long time, it is laborious to scrape; when the glue is mixed less, it is easy to remove the powder after forming
[0004] 2. Adding glue to putty powder during construction is prone to excessive harmful volatile substances such as formaldehyde, and its slow release will cause diseases

Abstract

The invention relates to talcum powder glue-free putty and a preparation method thereof. The talcum powder glue-free putty is prepared from the following raw materials in parts by weight: 960 to 1000 parts of talcum powder, 3 to 7 parts of hydroxypropyl methyl cellulose, 3 to 7 parts of polyvinyl alcohol, 5 to 15 parts of sodium bentonite, 0.5 to 1.5 parts of alkylamine and 3 to 7 parts of natural incense powder. According to the talcum powder glue-free putty, through scientific proportioning of various components, the talcum powder glue-free putty is barrier-free in blade coating during use, and indexes such as alkali resistance, water resistance, sanding property, drying time and bonding strength all reach a relatively high level. In addition, the raw materials do not contain components harmful to the environment, and contain a certain amount of natural incense powder, so that the environment can be kept fresh; and the preparation method is simple, easy to control and beneficial to large-scale production.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a talcum powder glue-free putty and a preparation method thereof. Background technique [0002] Putty powder is one of the essential raw materials in the construction process, but the existing putty powder has the following problems: [0003] 1. It is not easy to control the operation of adding glue to the putty powder during the construction process. When the glue is mixed for a long time, it is laborious to scrape; when the glue is mixed less, it is easy to remove the powder after forming. [0004] 2. Adding glue to putty powder during construction is prone to excessive harmful volatile substances such as formaldehyde, and its slow release will lead to diseases. [0005] Therefore based on this, propose the technical scheme of the present invention. Contents of the invention [0006] In order to solve the problems in the prior art, the invention provides a t...
