A production process of permanent antistatic synthetic paper additive

Abstract

The invention belongs to the technical field of antistatic additives, and specifically relates to a production process of a permanent antistatic synthetic paper additive, comprising the following steps: S1: dissolving lithium carbonate in deionized water to form a saturated solution; S2: in the S1 step On the basis of step S2, put the accelerator into the lithium carbonate solution for soaking, and heat the solution to dry the solution; S3: on the basis of step S2, put the accelerator, polypropylene and thermoplastic polyurethane elastomer into the mixture Mixing in the mill to obtain semi-finished products; S4: Based on the step S3, put the semi-finished products into the twin-screw extruder for extrusion, and the extruded products are sent to the plastic granulator to obtain finished products Granular additive; the antistatic additive prepared by the invention has good antistatic effect, and at the same time, the performance of the product can be improved to a certain extent after the additive is used, and the additive is easy to use and easy to disperse in the product raw materials.

Description

technical field [0001] The invention belongs to the technical field of antistatic additives, in particular to a production process of permanent antistatic synthetic paper additives. Background technique [0002] Synthetic paper, also known as chemical film paper, plastic paper, polymer paper, imitation paper film, pearlescent paper, etc., is mainly made of high molecular compounds, such as polyethylene, polypropylene, polystyrene, polyvinyl chloride instead of plant fibers. Raw materials, after "paper-like" treatment, are made into a new type of paper that is similar in appearance to ordinary plant fiber paper but has superior performance. At the same time, since the main component of synthetic paper is insulating plastic, the charge generated on the surface of the plastic will not leak and accumulate during use, and then the charge accumulated on the surface will cause dust to adhere, adhere, and repel. , Electric shock, discharge and other phenomena will affect the normal...

Problems solved by technology

However, common antistatic additives do not have other effects. At the same time, powdery additives are prone to agglomeration during the addition process, or the mixing time needs to be prolonged after addition to ensure that the additives are mixed evenly, resulting in slower production speed and increased production costs.

[0003] There are also some technical solutions about antistatic additives in the prior art. For example, the Chinese patent whose application number is CN201010550482.X discloses a kind of antibacterial antiaging antistatic plastic masterbatch and its preparation method, including the following components and parts by weight: poly 100 parts of ethylene, 25-40 parts of antibacterial agent, 1-3 parts of dispersant, 0-1 part of lubricant, 8-14 parts of antioxidant, 5-10 parts of light stabilizer, 40-60 parts of antistatic agent, 0.3-0.6 parts of joint agent, 0-20 parts of metal particles, 50-80 parts of composite inorganic flame retardant; however, the preparation cost of the antistatic plastic masterbatch is relatively high, and the cost performance is not high. It is easy to affect the color of the masterbatch, so that the prepared masterbatch cannot be applied to the preparation of synthetic paper
