Problems solved by technology
Since PVC materials are commonly used to make gloves on cotton liners at present, and PVC materials are poisonous and pollute the environment, and the gloves produced are prone to problems such as adhesion, discoloration, and deformation. The country has banned the use of PVC materials to make gloves
Although nitrile latex has many advantages, due to its low solid content (generally about 45%), poor viscosity and strong permeability, it is easy to produce glove liner penetration problems when making gloves, which greatly limits the use of nitrile latex.

Embodiment Construction
[0015] Embodiments of the present invention are described in further detail below:
[0016] First, prepare the nitrile latex mixed solution in the nitrile latex mixing tank, which is a mixed solution of nitrile latex and thickener, wherein nitrile latex is a coating latex, which has oil resistance, waterproof, environmental protection, etc., and is widely used For oil-resistant products. Thickener comprises cellulose acetate or sodium polyacrylate or polyvinyl alcohol and similar compounds, and is commercially available chemical product, and the weight proportion of the two is nitrile latex: thickener=100: 0.01-0.10, mixing Liquid concentration is 45%.
[0017] What the coagulant in the coagulant pool adopts is that concentration is the calcium salt methanol solution of 1-5%, and this calcium salt methanol solution comprises calcium chloride methanol solution, calcium nitrate methanol solution etc., the calcium salt methanol solution in the present embodiment adopts It is ca...

The invention belongs to a film-forming process of nitrile latex on cotton liner. Its main technical feature is that the cotton liner is dipped in the coagulant pool before dipping the nitrile latex, and then dipped in the nitrile latex mixed solution pool added with an appropriate amount of thickener—sodium polyacrylate, and then dried to complete the finished product. The overall process of the invention is simple, scientific and reasonable, and has no harm to the environment; the produced cotton liner products such as gloves not only fully reflect the advantages of nitrile latex, but also completely overcome many shortcomings of PVC gloves. , Wear-resistant, waterproof gloves.
Description
technical field [0001] The invention belongs to the technical field of latex film formation, in particular to a film formation process of nitrile latex on cotton liner. Background technique [0002] Nitrile latex belongs to a kind of artificial synthetic latex, with small molecular weight, oil resistance, wear resistance, waterproof, non-toxic, and no pollution to the environment. Since PVC materials are commonly used to make gloves on cotton liners at present, and PVC materials are poisonous and pollute the environment, and the gloves produced are prone to problems such as adhesion, discoloration, and deformation. The country has banned the use of PVC materials to make gloves. Although nitrile latex has many advantages, due to its low solid content (generally about 45%), poor viscosity and strong permeability, it is easy to produce glove liner penetration problems when making gloves, which greatly limits the use of nitrile latex. Application of nitrile latex in film-formin...
