Description

Technical Field

[0001] The invention relates to the technical field of CPVC pipes, and in particular to a preparation process of an antistatic, corrosion-resistant and high-performance CPVC pipe. Background Art

[0002] CPVC is mainly used to produce plates, rods, and pipes to transport hot water and corrosive media. It can maintain sufficient strength when the temperature does not exceed 100°C, and can be used for a long time under high internal pressure. The weight of CPVC is 1 / 6 of brass and 1 / 5 of steel, and it has extremely low thermal conductivity. Therefore, pipes made of CPVC are light in weight, have good thermal insulation performance, and do not require thermal insulation. CPVC pipes can be used as hot sewage pipes in factories, electroplating solution pipes, hot chemical reagent pipes, and wet chlorine gas pipes in chlor-alkali plants.

[0003] In the prior art, the antistatic and corrosion-resistant performance of CPVC pipes is poor during use, which leads to the easy accumulation of static electricity, resulting in the risk of discharge and fire. For this reason, we propose a preparation process for antistatic and corrosion-resistant high-performance CPVC pipes to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art that CPVC pipes have poor anti-static and corrosion resistance during use, which leads to easy accumulation of static electricity and the risk of fire caused by discharge, and to propose a preparation process for anti-static and corrosion-resistant high-performance CPVC pipes.

[0005] The present application provides a preparation process for an antistatic, corrosion-resistant, high-performance CPVC pipe using the following technical solutions:

[0006] A preparation process of an antistatic, corrosion-resistant, high-performance CPVC pipe comprises the following steps:

[0007] S1: Prepare raw materials, which include the following components in parts by weight: 20-35 parts of polyvinyl chloride resin, 65-80 parts of chlorinated polyvinyl chloride resin, 3-10 parts of heat-resistant resin, 4-8 parts of heat stabilizer, 2-8 parts of toughening agent, 1-5 parts of antistatic agent, 3-9 parts of impact modifier, 2-8 parts of colorant, 1-5 parts of chlorinating agent, 15-25 parts of light calcium, 3-9 parts of lubricant, 2-10 parts of flame retardant, 1-5 parts of polyethylene wax, 1-5 parts of monoglyceride, 2-6 parts of brightener, and mix all the raw materials according to the formula ratio;

[0014] Furthermore, in S1, the raw materials include the following components in parts by weight: 25-30 parts of polyvinyl chloride resin, 68-75 parts of chlorinated polyvinyl chloride resin, 5-8 parts of heat-resistant resin, 5-7 parts of heat stabilizer, 4-6 parts of toughening agent, 2-4 parts of antistatic agent, 5-7 parts of impact modifier, 4-6 parts of colorant, 2-4 parts of chlorinating agent, 18-22 parts of light calcium, 5-7 parts of lubricant, 5-7 parts of flame retardant, 2-3 parts of polyethylene wax, 2-3 parts of monoglyceride, and 3-5 parts of whitening agent.

[0015] Furthermore, in S1, the raw materials include the following components in parts by weight: 28 parts of polyvinyl chloride resin, 70 parts of chlorinated polyvinyl chloride resin, 6 parts of heat-resistant resin, 6 parts of heat stabilizer, 5 parts of toughening agent, 3 parts of antistatic agent, 6 parts of impact modifier, 5 parts of colorant, 3 parts of chlorinating agent, 20 parts of light calcium, 6 parts of lubricant, 6 parts of flame retardant, 2 parts of polyethylene wax, 2 parts of monoglyceride, and 4 parts of whitening agent.

[0016] Furthermore, in S1, polyvinyl chloride resin, chlorinated polyvinyl chloride resin, heat-resistant resin, heat stabilizer, toughening agent, antistatic agent, impact modifier, colorant, chlorinating agent, light calcium, lubricant, flame retardant, polyethylene wax, monoglyceride, and whitening agent are proportioned, and the proportioned raw materials are mixed to obtain a mixture.

[0017] Furthermore, in S2, the mixture consisting of polyvinyl chloride resin, chlorinated polyvinyl chloride resin, heat-resistant resin, heat stabilizer, toughening agent, antistatic agent, impact modifier, colorant, chlorinating agent, light calcium, lubricant, flame retardant, polyethylene wax, monoglyceride and whitening agent is preheated by a preheating device, the heating temperature is set to 30-50°C, and premixed by a stirring mechanism.

[0018] Furthermore, in S3, the preheated mixed material is heated by a heating device, the heating temperature is set to 90-105° C., and the heated mixed material is transported by a transport mechanism.

[0019] Furthermore, in S4, the heated mixed material is extruded and molded by a single screw extruder, and the temperature of the single screw extruder is set to 180-230°C.

[0020] Furthermore, in the step S5, the extruded tube is cooled and shaped by a cooling mechanism.

[0021] Furthermore, in S6, the shaped pipe is pulled by a pulling device, and the pipe is cut by a cutting machine.

[0022] Furthermore, in S7, the appearance, length and performance of the pipe are inspected by an inspection device, and the qualified pipe products are packaged by a packaging machine to obtain the CPVC pipe.

[0023] Antistatic agents are additives that are added to plastics or applied to the surface of molded products to reduce static electricity accumulation. Generally, according to different methods of use, antistatic agents can be divided into two categories: internal addition type and external coating type. The antistatic agents used for plastics are mainly internal addition type. Antistatic agents can also be divided into two categories according to their performance: temporary and permanent. Antistatic agents are substances that can increase the conductivity of the surface of the photosensitive film and prevent static electricity accumulation. They can be miscible with gelatin and used as the antistatic layer of the photosensitive film alone, or added to the emulsion protective layer, back layer, or directly added to the emulsion layer. Commonly used ones include phosphoric acid (such as amide phosphate), inorganic semiconductor salts (such as cuprous and silver halides), carbon black, sodium cellulose sulfate, etc. Antistatic agents generally have the characteristics of surfactants, and have both polar and non-polar groups in their structure. Commonly used polar groups (i.e., hydrophilic groups) include: anions of carboxylic acid, sulfonic acid, sulfuric acid, and phosphoric acid, cations of amine salts and quaternary ammonium salts, and groups such as -OH and -O-. Commonly used non-polar groups (i.e., lipophilic or hydrophobic groups) include: alkyl, alkylaryl, etc., thus forming five basic types of ASA commonly used in the fiber industry, namely, amine derivatives, quaternary ammonium salts, sulfates, phosphates, and polyethylene glycol derivatives. When ASA is used as a coating, the hydrophobic group is adsorbed on the surface of the material, and a layer of ASA molecules is formed on the outermost layer; when a copolymerization method is used to form a two-component fiber, the outer ASA molecular layer is destroyed, and the inner ASA can penetrate into the surface of the material; there is a smooth ASA molecular layer on the surface of the material, and the reduction of the surface friction coefficient reduces the probability of static electricity generation, but the external ASA has poor washing fastness, and it can be considered to use reactive compounds to form covalent bonds with the fiber at high temperatures;

[0024] Toughener refers to a substance that can increase the flexibility of the adhesive film layer. Some thermosetting resin adhesives, such as epoxy resin, phenolic resin and unsaturated polyester resin adhesives, have low elongation and high brittleness after curing. When the bonding part is subjected to external force, cracks are easily generated and rapidly expand, resulting in cracking of the adhesive layer. It is not fatigue-resistant and cannot be used for structural bonding. Therefore, it is necessary to find ways to reduce brittleness, increase toughness, and improve bearing strength. Any substance that can reduce brittleness, increase toughness, and does not affect the other main properties of the adhesive is called a toughener. Tougheners generally contain active groups and can react chemically with the resin. They are not completely compatible after curing and sometimes have to separate into phases. This will obtain a more ideal toughening effect, keep the heat deformation temperature unchanged or drop very little, and significantly improve the impact resistance. Some low molecular liquids or plasticizers added to the resin can also reduce brittleness, but the rigidity, strength, and heat deformation temperature are greatly reduced, which cannot meet the requirements of structural bonding. Therefore, plasticizers and toughening agents are completely different. Some linear polymer compounds are miscible with resins and contain active groups. They can participate in the curing reaction of resins, increase elongation at break and impact strength, but the heat deformation temperature is reduced. This substance is called a softener. Commonly used ones are liquid polysulfide rubber and liquid nitrile rubber. Since they can be made into structural adhesives when combined with resins in appropriate amounts, softeners are also classified as toughening agents. Although flexibility and toughening are interrelated and different concepts, it is actually difficult to strictly distinguish them. Theoretically, toughening is different from flexibility. Toughening does not soften the material as a whole, but rather changes the epoxy resin cured homogeneous system into a multiphase system, that is, the toughening agent aggregates into spherical particles to form a dispersed phase in the continuous phase composed of the cross-linked network of the epoxy resin. The crack resistance changes suddenly, and the fracture toughness is significantly improved, but the mechanical properties and heat resistance are less lost.

[0025] Polyethylene wax (ti ssuemat E) is a chemical material, in which the color of polyethylene wax is white small micro beads / flakes, formed by ethylene polymerization rubber processing agent, which has the characteristics of high melting point, high hardness, high gloss, snow-white color, etc. Polyethylene wax is a low molecular weight polyethylene homopolymer or copolymer widely used in coatings. The so-called wax means that this polymer finally floats in the surface of the coating in the form of microcrystals, playing a role similar to paraffin wax but more diverse and practical than paraffin wax. The main functions of polyethylene wax in solvent-based coatings are: matting, anti-scratch, anti-wear, anti-polishing, anti-imprinting, anti-adhesion, anti-precipitation, thixotropy; good lubricity and processability; metal pigment positioning. The working principle of polyethylene wax is as follows: polyethylene wax dissolves in the solvent at high temperature (about 100-140℃), and precipitates when cooled to room temperature, and exists in the coating in the form of microcrystals. Its thixotropy is conducive to the storage of the coating. After the coating is applied, it can migrate to the surface of the coating during the evaporation of the solvent, and finally form a "waxed" surface with other components of the coating. The role of polyethylene wax depends on the following factors: the variety and specification of polyethylene wax, the final particle size, the ability to migrate to the surface of the coating, the composition of the coating, the nature of the coated substrate, the construction and application method, etc.

[0026] Flame retardants are functional additives that make flammable polymers flame retardant. They are mainly designed for the flame retardancy of polymer materials. There are many types of flame retardants, which are divided into additive flame retardants and reactive flame retardants according to the method of use. Additive flame retardants are added to polymers by mechanical mixing to make polymers flame retardant. Additive flame retardants mainly include organic flame retardants and inorganic flame retardants, halogen flame retardants (organic chlorides and organic bromides) and non-halogen. Organic flame retardants are represented by bromine, phosphorus-nitrogen, nitrogen, red phosphorus and compounds. Inorganic flame retardants are mainly flame retardant systems such as antimony trioxide, magnesium hydroxide, aluminum hydroxide, and silicon. Reactive flame retardants participate in the polymerization reaction as a monomer, so that the polymer itself contains flame retardant ingredients. Its advantages are that it has little effect on the performance of polymer materials and has long-lasting flame retardancy.

[0027] In summary, this application includes the following beneficial technical effects:

[0028] The present invention uses polyvinyl chloride resin, chlorinated polyvinyl chloride resin, heat-resistant resin, heat stabilizer, toughening agent, antistatic agent, impact modifier, colorant, chlorinating agent, light calcium, lubricant, flame retardant, polyethylene wax, monoglyceride and brightener to obtain a CPVC pipe that not only has antistatic performance, but also effectively improves corrosion resistance and reduces the risk of fire caused by discharge due to static electricity accumulation.
