Problems solved by technology

[0006] But the tableware that existing plastic material is made is difficult to clean the oil stain on the surface of the tableware because of its lipophilicity, and in order to remove the oil stain on the surface of the tableware more conveniently and quickly, generally a large amount of tableware cleaning agent can be used. Extensive use will leave a lot of cleaning agent on the surface of the tableware, and long-term accumulation will affect people's health. In addition, because the cleaning agent contains many chemical compounds, the cleaning agent wastewater after tableware cleaning will cause great damage to the environment. harm

Abstract

The invention provides a modified polyester material and a preparation method thereof. The modified polyester material of the present invention comprises the following raw materials in parts by weight: 60-80 parts of copolyester, 5-15 parts of gas-phase SiO 2 , 2 to 5 parts of calcium carbonate, 0 to 2 parts of antibacterial agent, 5 to 15 parts of antistatic agent, 0 to 1 part of heat stabilizer, 5 to 10 parts of impact modifier, 0 to 1 part Antioxidant and 0-3 parts of pigment. The modified polyester material of the present invention has good oleophobic and hydrophilic properties, anti-skid properties, toughness, hydrolysis stability, and has the special functions of antibacterial, antistatic and excellent water contact angle. The preparation method of the present invention is simple, and the prepared modified polyester material can be used in the preparation of tableware. The tableware does not need to add cleaning agent when cleaning, and the tableware can be cleaned by washing with hot water at 80-90°C for 1-3 minutes, and the tableware The surface has no water beads hanging on the wall, especially suitable for applications in the food field.

Description

technical field [0001] The invention belongs to the technical field of polyester materials, and relates to a modified polyester material and a preparation method thereof. Background technique [0002] With the acceleration of people's life rhythm and the improvement of consumption level, fast food is closely related to people's life. Therefore, the problem of cleaning tableware for eating and drinking and tableware after meals cannot be ignored. Common tableware includes bowls, plates, lunch boxes, etc., mostly made of ceramics, and some made of plastic. Ceramic tableware needs to be fired at high temperature, consumes a lot of energy, and is not friendly to the environment. It belongs to the three high industries of "high energy consumption, high pollution, and high emissions". At present, plastic tableware on the market dominates the tableware market due to its light weight, low price and good mechanical properties. However, there are many defects and inconveniences in ...
