Problems solved by technology

Because they are made of granular fully alkalized polyvinyl alcohol, which is heated and dissolved or acetalized, and most of them are heated by coal-fired boiler steam heating, which not only consumes a lot of energy, but also pollutes the atmosphere with smoke and dust emissions. , and its finished products contain free formaldehyde, which will continue to release irritating formaldehyde gas that is poisonous to the human body during its use, causing bad pathogenic effects on people's work and life
And the existing adhesives of this type, because of their poor flexibility and weak impact resistance, cannot meet the needs of the modern construction industry, especially the increasing quality of decoration and decoration projects.

Embodiment Construction

[0023] In the following, the present invention will be further described in detail through specific implementation methods corresponding to the technical solutions described above.

[0024] One of the specific implementation modes is a kind of adhesive with ternary ingredients. A kind of aldehyde-free water-soluble adhesive, it is made up of three kinds of raw materials of partially alkalized polyvinyl alcohol powder, redispersed latex powder and hydroxypropyl methylcellulose; The weight ratio of said three kinds of raw materials is, partially alkalized Type polyvinyl alcohol powder: redispersed latex powder: hydroxypropyl methylcellulose=12:25:2. For its performance characteristics and scope of application, please refer to No. 4 listed in Table 1. After the three raw materials are weighed according to the said ratio, the product is made into a powder formaldehyde-free water-soluble adhesive after compounding and fully mixing, and then it can be put on the market after being ...

Abstract

Disclosed is a watersoluble sticker without aldehyde, belonging to the chemical sticker technical field, comparing of two or three ones from polyvinyl alcohol powder with partial being alkalized, redispersant latex powder and cellulose ether,which are mixed to be the product. The product has the characteristics of being powder watersoluble sticker without aldehyde or sticker. The invention has simple technique,low cost,no biological pollution,convenient usage,high adhering strength and good flexibility, it is a water soluble sticker without aldehyde for building to replace the 107 glue and 801 glue.

Description

technical field [0001] The invention relates to a formaldehyde-free water-soluble adhesive for construction, which belongs to the technical field of chemical adhesives. Background technique [0002] Said existing chemical adhesives are high in bonding strength, good in storage stability and long in pot life, and the raw materials used are continuously desirable, and are adopted by industries, especially building materials and construction industries, especially decoration and decoration projects. [0003] The currently widely used construction adhesives can be mainly divided into water-soluble polyvinyl formal adhesives (JC438-91) and water-soluble acetal adhesives, such as 107 glue and 801 glue. Because they are made of granular fully alkalized polyvinyl alcohol, which is heated and dissolved or acetalized, and most of them are heated by coal-fired boiler steam heating, which not only consumes a lot of energy, but also pollutes the atmosphere with smoke and dust emissions. ...
