Preferably, the emulsifier in the step S1 is sodium dodecyl benzene sulfonate.
Preferably, the curing agent in the step S1 is m-xylylenediamine as an amine curing agent.
Preferably, the stabilizer in the step S1 is a zinc-calcium stabilizer.
Preferably, the solidifying agent in the step S3 is methanol solution containing 1-5% of glacial acetic acid or 1-2% of calcium chloride by mass, and the soaking and homogenizing time is 60-90S.
Preferably, the soaking and spin-coating time in the step S4 is 15-25S.
Preferably, the temperature of the drying in the step S5 is 80-110 ℃ and the time is 1-2h.
In summary, the invention has the following beneficial effects:
Firstly, for the self-reduction performance against long-time pressure, the reaction mechanism is mainly based on the molecular structure and interaction of polyether sulfone (PES) and nitrile rubber (NBR), the polyether sulfone is a linear polymer, has higher mechanical strength, good thermal stability and chemical stability, the molecular chain of the polyether sulfone contains ether bonds and sulfonyl groups, the groups endow the polyether sulfone with excellent hydrolysis resistance and oxidation resistance, so that the coating can resist the physical and chemical attack of the outside, the nitrile rubber is a polar amorphous rubber, has excellent oil resistance, wear resistance and ageing resistance, the acrylonitrile groups in the molecular chain of the nitrile rubber provide good polarity, so that the nitrile rubber can form good compatibility and adhesiveness with other polar materials, the durability of the coating is enhanced, and when the polyether sulfone and the nitrile rubber are mixed, the interaction between the two is mainly expressed in the following aspects:
hydrogen bonding: the ether bond in the polyethersulfone and the polar group in the nitrile rubber can form a hydrogen bond, so that the binding force between the ether bond and the polar group is enhanced;
physical crosslinking: in the mixed latex, the linear molecular chain of polyethersulfone and the structure of nitrile rubber can form physical crosslinking points, so that the overall strength of the coating is improved;
Stress dispersion: the elastomer structure of the nitrile rubber can disperse stress when the coating is subjected to pressure, so that the coating is prevented from cracking or damaging;
The interaction between polyethersulfone and nitrile rubber allows the coating to deform to some extent without cracking when the coating is subjected to prolonged pressure. When the pressure is lost, the coating can quickly return to the original state due to hydrogen bonding and physical crosslinking, and the pressure-resistant property is exhibited.
The molecular chain of the polyphenylene benzodioxazole nano-cellulose has a benzene ring with stable structure, and has excellent wrinkle resistance and dimensional stability. The molecular chains of the selected polyphenylene benzodioxazole nano-cellulose are oriented along the radial direction, and the molecular chains on the longitudinal section are oriented along the fiber axis, so that the polyphenylene benzodioxazole nano-cellulose has the characteristics of high orientation, high strength and high modulus.
On the other hand, the nano-scale polyphenylene benzodioxazole cellulose is selected, because the nano-scale polyphenylene benzodioxazole cellulose has great advantages:
the specific surface area is increased, the volume is reduced, the reactivity is obviously improved, the low consumption is realized by functional implementation, and the cost is effectively reduced;
The molecular arrangement of the nanofiber is more regular, and the nanofiber can be self-organized;
in the mixing process with latex, benzene heterocycle and ether bond on the molecular chain of the polyphenylene benzodioxazole nano-cellulose and the molecular chain of the polyethersulfone are opened under the action of intermolecular hydrogen bond and amine curing agent, and nitrogen atoms on the molecular chain of the cellulose and unsaturated hydrogen atoms on the molecular chain of the butyronitrile are combined with an NH bond under the action of stabilizing agent; meanwhile, hydrogen atoms on cellulose molecular chains and unsaturated oxygen atoms on polyether sulfone molecular chains are combined with-OH bonds, the polyphenylene benzodioxazole nano-cellulose can be effectively attached to latex molecular chains, and the regularity and high modulus of the nano-cellulose are also endowed on the latex molecular chains to a great extent;
The high alignment characteristic of the polyphenylene benzodioxazole nanocellulose and the alignment of molecular chains which are mutually attached to the polyphenylene benzodioxazole nanocellulose are similar to the alignment characteristic of the polyphenylene benzodioxazole nanocellulose, and a multi-pivot bendable keel is added on one compliant chain, so that the flexible characteristic is ensured to be used when the latex coating is worn, and the state of the coating can be completely restored to a shaping state according to the high alignment and self-organization of the nanofibers when no pressure exists.
3. The composite latex disclosed by the invention is processed according to the shape self-reduction mechanism, so that the glove coating has the capability of reducing the initial shape, and even though the composite latex is subjected to product packaging, transportation and long-time storage in a warehouse or other deformation-causing processes, the composite latex still can keep and recover the original appearance shape to the greatest extent, and the performance of resisting long-time compression self-reduction is obtained, so that the glove coating has the capability of keeping the appearance for a long time.
