AI Technical Summary

Problems solved by technology

Creep resistance, fatigue resistance, good friction resistance, low wear and high hardness, with the greatest toughness among thermoplastics; good electrical insulation performance, little affected by temperature, but poor corona resistance
Non-toxic, weather resistance, good stability against chemicals, low water absorption, resistant to weak acids and organic solvents, but not resistant to hot water soaking, not alkali resistant
[0005] However, the PET masterbatch currently on the market usually only has a single dyeing function, and the PET crystallization speed is slow, which is likely to cause imperfect and uneven crystallization, and it is easy to produce fogging, resulting in opacity. The technology and equipment in the injection molding process put forward higher requirements, which is a burden for some start-up companies

Embodiment 1

[0025] Example 1: Configure 200kg moisture-removing colorless PET masterbatch

[0026] Under normal temperature and pressure, take the following components in mass percentage: 58% carrier, 1% colorant, 1% dispersant, 15% moisture-removing additive, 25% nucleating agent, after proportioning, add to the speed of 1000r / min mixer, mixed for 3 minutes to obtain a mixture, after taking it out, put the mixture into a kneader with a rotation speed of 500r / min, kneaded for 30 minutes, and kneaded to the coated state to obtain a kneaded product, after taking it out, the kneaded product Put it into an extruder with a host temperature of 100°C and extrude to obtain the extrudate, which is passed through special equipment, pelletized, cooled and packaged to make the desired moisture-removing colorless PET masterbatch, that is, this product Invented moisture-removing colorless PET masterbatch.

Embodiment 2

[0027] Example 2: Configure 200kg moisture-removing colorless PET masterbatch

[0028] Under normal temperature and pressure, take the following components in mass percentage: 60% carrier, 3% colorant, 3% dispersant, 15% dehumidification additive, and 19% nucleating agent. In a mixer with a speed of 800r / min, mix for 4 minutes to obtain a mixture. After taking it out, add the mixture to a kneader with a rotation speed of 800r / min, knead for 40 minutes, and knead to a coated state to obtain a kneaded product. After taking it out, the kneaded product Put it into an extruder with a host temperature of 150°C and extrude to obtain the extrudate, which is passed through special equipment, pelletized, cooled and packaged to make the desired moisture-removing colorless PET masterbatch, that is, this product Invented moisture-removing colorless PET masterbatch.

Embodiment 3

[0029] Example 3: Configure 200kg moisture-removing colorless PET masterbatch

[0030] Under normal temperature and pressure, take the following components in mass percentage: 56% carrier, 2% colorant, 2% dispersant, 15% dehumidification additive, 25% nucleating agent. In a mixer with a speed of 1300r / min, mix for 5 minutes to obtain a mixture. After taking it out, add the mixture to a kneader with a rotation speed of 1300r / min, knead for 45 minutes, and knead to a coated state to obtain a kneaded product. After taking it out, the kneaded product Put it into an extruder with a host temperature of 200°C and extrude to obtain the extrudate, which is passed through special equipment, pelletized, cooled and packaged to make the required moisture-removing colorless PET masterbatch, that is, this product Invented moisture-removing colorless PET masterbatch.

Abstract

The invention discloses a dehumidifying colorless PET (polyethylene Terephthalate) color master batch which is prepared from the components in percentage by weight as follows: 40-60% of carrier, 1-3% of coloring agent, 1-3% of dispersant, 5-15% of dehumidifying additive and 15-25% of nucleating agent. The invention further discloses a preparation method of the dehumidifying colorless PET color master batch. According to the dehumidifying colorless PET color master batch provided by the invention compared with color master batches marketed with similar functions, the price is more economical, and the production cost of a plastic process is reduced. With the adoption of an integral production mode, the production process is reduced and the energy resources are saved. According to the invention, the structure of PET grains is further changed, so that the crystallizing efficiency is improved, the mechanical performance is increased, the forming period is shortened and the economic benefit of enterprises is improved. According to the invention, novel components are adopted, and the use level of harmful substances is reduced, so that the harmful substances are substantially not volatilized without affecting the health of a human body. The color master batch is suitable for application and use in the manufacturing industry.

Description

technical field [0001] The invention relates to a color masterbatch, in particular to a moisture-removing colorless PET color masterbatch. Background technique [0002] The molecular structure of PET plastic is highly symmetrical and has a certain crystal orientation ability, so it has high film-forming properties; PET plastic has good optical properties and weather resistance, and amorphous PET plastic has good optical transparency. ; Another PET plastic has excellent wear resistance friction and dimensional stability and electrical insulation. [0003] Bottles made of PET are widely used because of their high strength, good transparency, non-toxicity, impermeability, light weight, and high production efficiency; PBT and PET have similar molecular chain structures, and most of their properties are the same, but the main The chain has changed from two methylene groups to four, so the molecule is more flexible and the processing performance is better. [0004] PET is a milk...
