The further setting of the present embodiment, wherein finished product preparation step include:
Step 8: squeezing into protecting colloid described in step 7 into a polymeric kettle, while OP-10 and 70% is added
Load weighted potassium peroxydisulfate simultaneously covers, and 20% load weighted vinylacetate is added;
Step 9: stirring 10 minutes, after being warming up to 60 degrees Celsius, stop heating, it is allowed to flow back;
Step 10: remaining vinyl acetate is added dropwise and potassium peroxydisulfate carries out polymerization reaction after reflux;
Step 11: allowing it to be warming up to 85 degrees Celsius after vinyl acetate completion of dropwise addition and keeping the temperature 1 hour;
Step 12: being cooled to 70-75 degrees Celsius after heat preservation, o-2 potassium acid dibutyl ester is added;
Step 13: temperature is down to 60 degrees Celsius, sodium bicarbonate is added, sodium bicarbonate is that the sodium bicarbonate that concentration is 10% is molten
Liquid;
Step 14: stirring 15 minutes, discharge finished product.
Specifically, formaldehyde is added dropwise in the step 3, rate of addition control was dripped off at 40 minutes.
Specifically, the step 4 kind condensation reaction is specifically that occur half milky white for heat preservation to solution after formaldehyde completion of dropwise addition
Color, as condensation terminal.
Specifically, the step 10 is specifically that remaining vinyl acetate is added dropwise, remaining persulfuric acid is added after being added dropwise 2 hours
Potassium, and a potassium peroxydisulfate is added at interval of half an hour, entire polymeric reaction temperature control is at 80-85 degrees Celsius.
Specifically, the step 11 vinyl acetate was completed to be added dropwise within 7 hours.
It in above-mentioned technical proposal, is learnt according to research, hydrogen bond is the root that glue freezes, therefore to solve the problems, such as to freeze
It just needs to reduce the active force of hydrogen bond, that is, reduces the quantity of hydroxyl, therefore use polyvinyl alcohol contracting first under the conditions of certain temperature
The quantity of the method reduction-OH of aldehyde, while it being allowed to form Liu Yuanhuan to greatest extent, increase steric hindrance, while whole chain agent is added and subtracts
Few branch degree.
Specifically, hydrochloric acid is added in step 2 as catalyst, in the condensation reaction, catalyst, which is added, can greatly speed up contracting
The speed of reaction is closed, and hydrochloric acid when concentration is 1, obtains best catalytic effect as catalyst.
Specifically, formaldehyde is added dropwise in step 3, formaldehyde is that reactant plays very big influence to condensation reaction naturally, and concentration is big
Reaction rate is fast, but for the protecting colloid for preparing freeze proof glue after condensation product forms a certain number of hexatomic rings, just
It is unnecessary to prevent going on smoothly for polymerization reaction because of the presence of formaldehyde with the presence of formaldehyde.Also therefore, in aldolisation knot
Shu Hou, it is necessary to dispose formaldehyde, therefore oxidant need to be added in step 6, with oxidation of formaldehyde at carbon dioxide and water.
Specifically, even if controlling temperature well, but also inevitably having many branches due to the complexity of condensation reaction
Structure generates, and branched structure is unfavorable to production glue and frost resistance, therefore uses the whole chain agent of addition and he is organized into straight chain
Or the molecular state that branch is less.
Above the embodiments of the present invention are described in detail, but the present invention is not limited to described embodiments.It is right
It include portion to these embodiments in the case where not departing from the principle of the invention and spirit for those skilled in the art
Part carries out a variety of change, modification, replacement and modification, still falls in protection scope of the present invention.
