Description
Technical Field
The invention relates to the technical field of antistatic agents, in particular to a liquid antistatic agent containing inorganic salt ions and used for PVC.
Background
PVC is used as general plastic, and has the advantages of low price, good flame retardance, acid and alkali corrosion resistance, wear resistance and the like, so the PVC has wide application. However, since PVC has high surface resistance and poor conductivity, static electricity is generated on the surface due to friction during use, and further dangerous accidents such as fire or explosion occur, so that the application of antistatic unmodified PVC in coal mine and electronic industry is limited.
The surface resistance of the material is reduced by two methods, one method is an external coating surface treatment type antistatic agent, most of the antistatic agents are anionic and cationic surfactants, the antistatic effect of the antistatic agents is good in a short time, the performance of the material is not influenced, the duration time of the antistatic performance is short, and the antistatic performance can be failed after washing or rubbing. The other is an internal addition type antistatic agent, which is a polyurethane antistatic material prepared by taking inorganic materials such as carbon black, graphite, carbon nano tubes, metal oxides, metals and the like as antistatic components, and has the advantages that the added polyurethane material has good antistatic property and low cost, but has the defects that the addition amount of the antistatic agent is large, the expected effect can be achieved only when the addition amount reaches about 30 percent, and the mechanical property of the material is greatly influenced. To reduce the surface resistance of PVC, antistatic agents are typically added to PVC.
Patent CN 104672715 discloses an environment-friendly antistatic agent, which is a mixture of anionic sodium dodecyl benzene sulfonate, quaternary ammonium salt (sodium octadecyl dimethyl hydroxyethyl quaternary ammonium nitrate) and the like, the antistatic effect is general, and the surface resistivity of the blended PVC resin is 10 8 -10 10 . Patent CN 104962011A uses fatty acid monoglyceride and inorganic metal salt mixed as an antistatic agent, but the compatibility of fatty acid monoglyceride and PVC is poor, especially in an environment with a high temperature, precipitation is fast, and the fatty acid monoglyceride cannot dissolve the inorganic salt to form an ionic liquid. Patent CN106117887A discloses a compounding scheme of fatty acid PEG monoester, ionic compound and mineral oil, where the ionic compound is lithium perchlorate, sodium perchlorate and other substances, and the ionic compound is a key substance with an antistatic effect, and the ionic compound has poor solubility in fatty acid PEG monoester and mineral oil, and cannot achieve a good antistatic effect, and cannot achieve good dispersion in the processing process, so that the ionic compound cannot perform an optimal effect.
Disclosure of Invention
Based on the defects of the prior art, the invention provides a liquid antistatic agent containing inorganic salt ions for PVC, which belongs to a compound liquid antistatic agent containing inorganic salt ions, has good antistatic property, good processing property, high heat-resistant stability, good compatibility with PVC and low cost, and can be used for PVC products with high requirements on antistatic property.
The invention adopts the following technical scheme:
on one hand, the invention provides a liquid antistatic agent containing inorganic salt ions for PVC, which is prepared from the following raw materials in parts by weight:
30-70 parts of coconut oil diethanolamide, 5-30 parts of polyethylene glycol monooleate, 10-30 parts of ionic compound and 10-30 parts of solubilizer.
Wherein the coconut oil diethyl pure amide has a molecular formula of C 11 H 23 CON(CH 2 CH 2 OH) 2 And C 11 H 21 CON(CH 2 CH 2 OH) 2 A mixture of (a);
the molecular formula of the polyethylene glycol monooleate is C 17 H 33 COO(CH 2 CH 2 O) n-H, which is polyethylene glycol 400 monooleate or polyethylene glycol 600 monooleate.
Further, the liquid antistatic agent is prepared from the following raw materials in parts by weight:
45-70 parts of coconut oil diethanolamide, 5-30 parts of polyethylene glycol monooleate, 10-25 parts of ionic compound and 10-30 parts of solubilizer.
Further, the solubilizing agent is selected from: one or more of diethylene glycol monobutyl ether, diethylene glycol, triethylene glycol, dipropylene glycol, tripropylene glycol, polyethylene glycol 200, polyethylene glycol 400 and polyethylene glycol 600.
Further, the ionic compound is selected from one or more of sodium acetate, lithium acetate, sodium perchlorate, lithium perchlorate, potassium thiocyanate, sodium thiocyanate and potassium chloride. Further, the ionic compound is nanoscale.
Further, the liquid antistatic agent is prepared from the following raw materials in parts by weight:
45-70 parts of coconut oil diethanolamide, 5-30 parts of polyethylene glycol monooleate, 10-25 parts of sodium perchlorate and 10-30 parts of diethylene glycol monobutyl ether.
In one aspect, the present invention provides a method for preparing a liquid antistatic agent containing inorganic salt ions for PVC, comprising the steps of:
mixing and stirring the coconut oil diethanolamide and the solubilizer uniformly, heating to 70-120 ℃, adding the ionic compound under the condition of stirring until the ionic compound is completely dissolved, cooling to 60 ℃, adding the polyethylene glycol monooleate, stirring to be clear, and cooling to obtain the liquid antistatic agent.

Compared with the prior art, the technical scheme provided by the invention has the following beneficial effects:
an ionic compound is a relatively high-efficiency antistatic agent, a sodium perchlorate plasma compound is used as a PVC antistatic agent in the prior art, but the problem of solubility of the ionic compound cannot be solved, the ionic compound is relatively high in polarity and can be dissolved only by using a relatively high-polarity polyhydroxy solvent, and in the prior art, the ionic compound is generally mixed with fatty acid monoglyceride, fatty acid polyoxyethylene ester and the like and cannot be completely dissolved to play a role. The invention uses the high temperature resistant solubilizer to fully dissolve the inorganic salt ionic compound to play a larger effect, can effectively solve the problem of the solubility of the inorganic salt ionic compound, forms a complete ionic liquid solution system, improves the antistatic effect of PVC products, has good processing performance, easy addition and dispersion, high utilization efficiency of raw materials, more durable antistatic performance and lower cost, and can be widely applied to products such as PVC conveyor belts, PVC wind cylinders and the like in mines.
The coconut oil diethanolamide and the solubilizer are added into the antistatic agent, so that the coconut oil diethanolamide and the solubilizer are good in intersolubility after heating, the cohesion of a system is enhanced, and good adhesion is given; the inorganic salt ionic compound is completely dissolved and dispersed after being added and generates a complex reaction with the system, so that the ionic compound is stably dispersed in the system, a good synergistic effect is achieved, layering is avoided, and a long-acting antistatic effect is achieved; and polyethylene glycol monooleate is added for dispersion, so that the viscosity of the antistatic agent is reduced, the low-temperature fluidity is ensured, the stable dispersion of inorganic salt is promoted, and the prepared antistatic agent is liquid after being cooled, has stable property and good intersolubility of components and is not layered.
