Problems solved by technology

[0004] The purpose of the present invention is to solve the problem in the prior art that polyester resins are used in a large amount and in a wide range, and after they are scrapped, they are extremely cumbersome to handle and difficult to degrade, so they are often buried deep in the soil, causing environmental problems. Deterioration, affecting the health of nearby organisms, causing irreversible losses, and a biodegradable polyester resin composition with antistatic ability is proposed

Embodiment 1

[0041] Embodiment 1: On the basis of percentage content 100%, wherein each raw material is polyester resin 60%, polylactide 5%, polybutylene succinate 15%, halogen reagent 1%, polycarbonate 8%, 8% polyethylene terephthalate, and 1% additive, the antistatic and biodegradable capabilities of the polyester resin composition are the same.

Embodiment 2

[0042] Embodiment 2: On the basis of percentage content 100%, wherein each raw material is polyester resin 60%, polylactide 1%, polybutylene succinate 9%, halogen reagent 1%, polycarbonate 8%, 20% polyethylene terephthalate, and 1% additive, the antistatic ability of the polyester resin composition is stronger, and it is more durable when its biodegradability becomes weaker.

Embodiment 3

[0043] Embodiment 3: On the basis of percentage content 100%, wherein each raw material is polyester resin 60%, polylactide 10%, polybutylene succinate 15%, halogen reagent 1%, polycarbonate In the case of 5%, polyethylene terephthalate 8%, and 1% additive, the biodegradability of the polyester resin composition is stronger, and its service life is reduced to a certain extent.

[0044] Working principle: Polyester resin is produced by reacting polyester resin, polylactide, polybutylene succinate, polycarbonate, and polyethylene terephthalate with halogen-based reagents and additives, among which Polylactide and polybutylene succinate have excellent biodegradability, through dissolution, enzymolysis, phagocytosis, etc. in the organism, they are continuously excreted from the body during the process of tissue growth, and repaired accordingly Thereby completely replacing the position of the implanted material, so that the material does not remain in the body, so when the composit...

Abstract

The invention relates to the technical field of polyester resin, in particular to a biodegradable polyester resin composition with antistatic capacity. The high-elasticity polyester resin is prepared from the following components in percentage by mass: 60% of polyester resin, 1%-10% of polylactide, 1%-15% of poly (butylene succinate), 1% of a halogen-based reagent, 2%-8% of polycarbonate, 5%-20% of polyethylene terephthalate and 1% of an additive, the elastic modulus of the polylactide is 3300-3500 MPa, and the bending modulus of the polylactide is 110-120 MPa; the polylactide is small in selection range of elastic modulus and flexural modulus, so that the polylactide is more sufficient in reaction, the poly (butylene succinate) is a white semi-crystalline polymer, and the water content is 0.15%. The problems that in the prior art, due to the fact that the use amount of polyester resin is large, the range is wide, and the polyester resin is extremely troublesome to treat and difficult to degrade after being scrapped, the polyester resin is often deeply buried in soil, the environment is deteriorated, the health state of nearby organisms is affected, and irreversible loss is caused are solved.

Description

technical field [0001] The invention relates to the technical field of polyester resins, in particular to a biodegradable polyester resin composition with antistatic capability. Background technique [0002] Polyester resin is a general term for polymer compounds formed by polycondensation of diols or dibasic acids or polyols and polybasic acids. Polyester resins are divided into saturated polyester resins and unsaturated polyester resins. Unsaturated polyester adhesives are mainly composed of unsaturated polyester resins, pigments and fillers, initiators and other additives. The adhesive has low viscosity, easy wetting, and good manufacturability. After curing, the adhesive layer has high hardness, good transparency, high brightness, can be quickly cured under pressure at room temperature, has good heat resistance, and good electrical properties. The disadvantages are large shrinkage, low adhesive toughness, poor chemical medium resistance and water resistance, and are us...
