Abstract
The invention discloses a kind of preparation method of high strength acrylic acid amides glue, comprise the steps of：1）Pre-cast polyacrylamide；2）Polyethylene dissolving alcohol；3）Add acrylamide；4）Add ammoniacal liquor：Temperature in reactor is down to 60 DEG C, 80 ~ 90g ammoniacal liquor is then added；5）Add water retention enhancing agents：2.5g water retention enhancing agents are melted with clear water first, are then added to reactor；6）Add ammonium persulfate：50g ammonium persulfates are added into reactor, 30min is reacted；7）Add sodium hydrogensulfite；8）Colloid is mixed：By step 7）In obtain special thick shape colloid and step 1）In obtained polyacrylamide solution mix, then plus clear water is to 1000kg, produce acrylamide glue.Rate of drying when acrylamide glue produced by the present invention has very high intensity and substantially reduces construction, prevents the situation of plucking peeling from occurring.
Description
Technical field
The present invention relates to a kind of preparation method of high strength acrylic acid amides glue, applied to glue processing technique field.
Background technology
Acrylamide glue is usually used in building trade, and putty is generally mixed into powder and then is applied and is scraped on wall, but city
The acrylamide glue commonly used on field, intensity is relatively low and rate of drying is too fast in construction, and water retention property is poor, holds in construction
Easily there is plucking peeling, difficult batch of situation about scraping, while the cost of in the market production acrylamide glue is higher, directly affects enterprise
The economic benefit of industry.
The content of the invention
The problem of to solve above-mentioned, the invention discloses a kind of preparation method of high strength acrylic acid amides glue, comprising with
Lower step：
1）Pre-cast polyacrylamide：Carrying the previous day is placed in 100kg clear water in container, adds polyacrylamide 0.4kg, stirring is extremely
Polyacrylamide is completely dissolved standby；
2）Polyethylene dissolving alcohol：Plus 100kg clear water is added in reactor, 70 DEG C are warming up to, mixer is opened and adds the poly- second of 7kg
Enol, then proceedes to be uniformly heating to after 95 DEG C, 25 ~ 30min of insulated and stirred；
3）Add acrylamide：7kg acrylamides are added into reactor, acrylamide is melted with clear water first, acrylamide
Mass ratio with clear water is 1:3, then together added together with clear water to reactor；
4）Add ammoniacal liquor：Temperature in reactor is down to 60 DEG C, 80 ~ 90g ammoniacal liquor is then added；
5）Add water retention enhancing agents：2.5g water retention enhancing agents are melted with clear water first, are then added to reactor；
6）Add ammonium persulfate：50g ammonium persulfates are added into reactor, 30min is reacted；
7）Add sodium hydrogensulfite：45g sodium hydrogensulfites are melted with clear water first, are then added to by step 6）It is reacted
In reactor, stirring 2min after, close mixer, stand reaction, to reactor in liquid be in special thick shape；
8）Colloid is mixed：By step 7）In obtain special thick shape colloid and step 1）In obtained polyacrylamide solution be blended in one
Rise, then add clear water to 1000kg, produce acrylamide glue.
Above-mentioned ammonium persulfate and sodium hydrogensulfite is technical grade.
Using the technical program, the beneficial effects of the invention are as follows：Obtained acrylamide glue has very high intensity, glues
Performance is tied good, while adding water retention enhancing agents, the rate of drying of acrylamide glue when can reduce construction, it is to avoid plucking occur
The generation of a problem that peeling, while production cost is reduced, improves the economic benefit of enterprise.
Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, tie below
Specific embodiment is closed, the present invention is expanded on further.
The invention discloses a kind of preparation method of high strength acrylic acid amides glue, comprise the steps of：
