Description
Technical field
It is specifically a kind of that high viscosity paste is prepared using emulsion method the invention belongs to macromolecule chemical industry technical field
The production method of resin.
Background technology
China is the production base of world's safety and industrial gloves, and the sector is larger to pasting the consumption of resin, and at present only
The P737 for having Sweden can be used alone, but price is higher, and domestic rouge and powder can partly substitute P737, but
There is the lacklustre phenomenon of gloves, thus most producers using more than 3 kinds of paste resin be used in mixed way come
Reach requirement.Annual the sector should be more than 100,000 tons to the consumption of resin, the imitative rubber labour protection of non-liner
More than 20,000 tons, imitative rubber safety and industrial gloves requirement paste resin viscosity is high at present and is easy to deaeration for gloves consumption,
Product is glossy.The sector has new processing producer to go into operation every year, imitates at the demand of rubber safety and industrial gloves
In the trend for rising.
The content of the invention
