Problems solved by technology

Polyamide has excellent properties such as toughness, wear resistance, impact resistance, fatigue resistance, corrosion resistance, oil resistance, solvent resistance, non-toxicity, good self-extinguishing property, and good electronic insulation. , engineering plastics with good self-lubricating properties are widely used in industries such as automobiles, electronics, and mechanical equipment, and are currently research hotspots; however, nylon has poor toughness due to its high polarity and high crystallinity, especially Nylon 6 has low impact resistance in dry state and low temperature, and has obvious notch sensitivity

Abstract

The present invention discloses a high tough resin and its preparation methods; its steps include: (2‑ methyl oxyl oxygen) ‑ acetic acid, 3‑ protected amino acid ‑ cytane carboxylic acid and organic alkali reactionReform 3‑ Protective amino acid ‑ cytane carboxylic acid; modify 3‑ protected amino acid ‑ cycol carboxylic acid, mix of mixture of mixture of amino -containing amino groups to obtain a mixture A; put mixed A in the reactor, Seal, nitrogen replacement, discharge air in the kettle, nitrogen filling at 180 ~ 250 ℃, the pressure is 0.6 to 1.5MPa, and the mixture B will be obtained.The material outlet valve, the material is leading, the cold water tank, the granular cutter cut the granules, and dry it to obtain high tough resin; the high tough resin has excellent light transmission and lower fog, that is, it has better transparencyAs well as excellent solvents, at the same time, it has high toughness.

Description

Technical field [0001] The invention is a high -molecular material technology field, which specializes in a high tough resin and its preparation methods. Background technique [0002] The transparent resin occupies an important position in the plastic industry, and is widely used in the fields of decorative sheets, plates, twisted films, and alien profiles. Therefore, people are committed to studying the toughness of plastic and maintaining its highly transparentness. Polyvinyl chloride (PVC) is the second plastic variety of global production second only to polyethylene. In order to further expand its application field, a variety of PVC transparent modified agents have been developed. The polyamide has excellent characteristics such as strong abrasion and abrasion, impact resistance, fatigue resistance, corrosion resistance, oil resistance, solvent resistance, non -toxic, good self -extinguishing, good electronic insulation, etc. It is a kind of high mechanical strength, good for...
