Abstract
The invention discloses a kind of adhesive with anti-freezing property, it the advantage is that：Conventional several acid catalysts are hydrochloric acid, sulfuric acid, phosphoric acid in the condensation reaction, the acid of the amount concentration of same substance is so that the catalytic activity of hydrochloric acid is big, consumption is few, therefore generally condensation catalyst is made with hydrochloric acid, glue made from other acid catalysis, its viscosity and anti-freezing property are not so good as hydrochloric acid.
Description
Technical field
The present invention relates to a kind of adhesive area, more particularly to a kind of adhesive with anti-freezing property.
Background technology
Prepared using polyvinyl alcohol and there is condensation reaction in adhesive, acid has been catalytic action in the condensation reaction.
Several acid catalysts commonly used in condensation reaction are hydrochloric acid, sulfuric acid, phosphoric acid etc., and the sour catalysis of the amount concentration of same substance is lived
Property, consumption are all different.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of adhesive with anti-freezing property.
In order to solve the above technical problems, the technical scheme is that：A kind of adhesive with anti-freezing property, it is innovated
Point is：It is prepared into by the component of following portions by weight：70-90 parts of polyvinyl alcohol, 30-35 parts of formaldehyde, 4-6 parts of catalyst, hydrogen
1-2.5 parts of sodium oxide molybdena, 4-6 parts of sodium sulfite, wherein catalyst are one kind in phosphoric acid, hydrochloric acid, oxalic acid.
Further, the catalyst is hydrochloric acid.
The advantage of the invention is that：Conventional several acid catalysts are hydrochloric acid, sulfuric acid, phosphoric acid in the condensation reaction, identical
The acid of substance withdrawl syndrome generally makees condensation catalyst so that the catalytic activity of hydrochloric acid is big, consumption is few with hydrochloric acid, and other acid are urged
Change obtained glue, its viscosity and anti-freezing property are not so good as hydrochloric acid.
Embodiment
The invention discloses a kind of adhesive with anti-freezing property, it is prepared into by the component of following portions by weight：Poly- second
70-90 parts of enol, 30-35 parts of formaldehyde, 4-6 parts of catalyst, 1-2.5 parts of sodium hydroxide, wherein 4-6 parts of sodium sulfite, catalyst
For phosphoric acid.
The laboratory preparation step for preparing adhesive by above-mentioned formula is as follows：
（1）Charging dissolving：The polyvinyl alcohol of tested number and the deionized water of tested number are added into 250mL four-hole bottle, is started
Stirring, is gradually heated up being warming up to 85 DEG C, until polyvinyl alcohol is completely dissolved；
（2）Acidity adjustment：It is lower with dropper dropwise addition concentrated phosphoric acid being stirred continuously, adjust pH=2.0 ~ 2.5；
（3）Aldolisation：With the 10mL formaldehyde for measuring tested number, it is slowly added drop-wise to four-hole bottle with constant pressure funnel
It is interior, control rate of addition；
（4）Reaction is maintained：Maintenance reaction system reacts 45min at 80 ~ 90 DEG C or so, until reaction is complete；
（5）Terminating reaction：Stop heating.The sodium hydroxide solution prepared is added dropwise（Concentration is 10%, can also be intended as needed
It is fixed）, adjust pH=7.0 ~ 7.5；
（6）Collect product：Being cooled to 45 DEG C or so can discharge.
Embodiment 2
On the basis of embodiment 1, catalyst chooses hydrochloric acid.
Embodiment 3
On the basis of embodiment 1 or 2, catalyst chooses oxalic acid.
The viscosity and frost resistance for the sample produced in detection embodiment 1,2,3, comparing result such as following table,
| Glue viscosity（mPa.s） | Anti-freezing property（0-2°） | |
| Embodiment 1 | 1030 | It is poor |
| Embodiment 2 | 3421 | Very well |
| Embodiment 3 | 1188 | Typically |
It can be seen that, when other experiment conditions are constant, glue made from phosphoric acid, Catalyzed by Oxalic Acid, its viscosity and anti-freezing property are not so good as salt
Acid, the effect of oxalic acid is better than phosphoric acid.
The general principle and principal character of the present invention has been shown and described above.It should be understood by those skilled in the art that,
The present invention is not limited to the above embodiments, merely illustrating the principles of the invention described in above-described embodiment and specification,
Without departing from the spirit and scope, various changes and modifications of the present invention are possible, and these changes and improvements all fall
Enter in scope of the claimed invention.The scope of the present invention is defined by the appended claims and its equivalents.
