Abstract
The invention relates to polyacrylamide slurry which is characterized by comprising the following components by weight: modified starch 20 to 50, microcrystalline cellulose 5 to 15, acrylamide 20 to 70 and PVA (polyvinyl acetate) 1 to 5. According to the invention, nanometer microcrystalline cellulose and polyacrylamide are combined through electrostatic interaction, which enables glass-transition temperature of the slurry to be changed, thereby effectively improving viscosity of the polyacrylamide slurry after moisture absorption and reducing usage amount of PVA.
Description
Technical field
The present invention relates to a kind of polyacrylamide slurry, viscosity does not have too big change after the moisture absorption, belongs to the textile chemistry field.
Background technology
The polyacrylamide slurry; All there are sticking serious phenomenon in PMA and polyacrylamide again; One of reason be because: contain too much hydrophilic radical in the synthetic slurry, strong absorptive makes the easy moisture absorption of dried serous coat and is partly dissolved, and has certain viscosity; Thereby on loom, occur the sticking again deficiency of moisture absorption easily, thereby influence weave effect.Another reason is to be that the slurry vitrification point of synthesizing is low excessively, demonstrates the high elasticity that is prone to deformation in the serviceability temperature interval, and it is inter-adhesive that the characteristic that is prone to deformation is prone to sizing; Thereby produce again sticking phenomenon; Influence weave effect, present research direction is to change above two specific characters through the appropriate molecular design, reaches the increase consumption; Promote the consumption of converted starch, thereby reduce the consumption of PVA.
Summary of the invention
Technical problem to be solved by this invention provides a kind of polyacrylamide slurry.
For solving the problems of the technologies described above, the present invention realizes like this
A kind of polyacrylamide slurry is characterized in that comprising the following component in weight portion; Converted starch 20-50, microcrystalline cellulose 5-15, acrylic acid amides 20-70, PVA1-5.
The present invention has following positive effect: microcrystalline cellulose is prepared by native cellulose, can be used as drug excipient and disintegrant at medical industry, on coatings industry, utilizes its thixotropy and thickening property thickener and the emulsifying agent as water based paint.Nano micro crystal cellulose has cellulosic basic structure and performance, has biological degradability, recyclability, and have huge specific area, adsorption capacity and high reactivity.The nano-sized crystal cellulose combines through static with polyacrylamide, changes the glass transition temperature of slurry, and the moisture absorption that effectively improves the polyacrylamide slurry is viscosity again, and can reduce the use amount of PVA.
The specific embodiment
Below in conjunction with the specific embodiment the present invention is done further detailed description.
A kind of polyacrylamide slurry is characterized in that comprising the following component in weight portion; Converted starch 20-50, microcrystalline cellulose 5-15, acrylic acid amides 20-70, PVA1-5.
The weight of the component that embodiment 1-4 is adopted such as table 1 (units)
| ? | Embodiment | Embodiment | Embodiment | Embodiment |
| Converted starch | 20.5 | 25.3 | 50.0 | 36.7 |
| Microcrystalline cellulose (500nm) | 5.3 | 7.3 | 10.5 | 15.0 |
| Acrylic acid amides | 20.3 | 40.5 | 53.2 | 70.0 |
| PVA | 1.2 | 3.2 | 5.0 | 4.1 |
The slurry that adopts present embodiment 1 preparation experimentizes on the polyester-cotton blend fine cloth product at T/C, and the rate of sizing is 14.32%, and regain is 3.05%, and the enhancing rate is 11.28%, and subtracting the rate of stretching is 29.08%, and it is all right that filoplume pastes volt.
The above-mentioned specific embodiment does not limit technical scheme of the present invention in any form, and the technical scheme that mode obtained that every employing is equal to replacement or equivalent transformation all drops on protection scope of the present invention.
