Embodiment Construction

[0020] A plastic bag prepared from modified waste tire rubber powder, which is made of the following components in parts by weight: linear low density polyethylene 84, ABS resin 18, modified waste tire rubber powder 7, α-methylstyrene ring two Polymer 1, polyacrylamide 0.4, starch 6, rosin 3, acrylamide 2, C9 petroleum resin 1, bisphenol monoacrylate 0.8, polyvinyl alcohol 0.5;

[0021] The waste tire rubber powder is made of the following components in parts by weight: waste tire 20, bentonite 0.5, urea-formaldehyde resin 1, polylactic acid 0.8, calcium stearate 0.5, glycerin 3; the preparation of the modified waste tire rubber powder The method is:

[0022] 1) The bentonite is calcined at 486°C for 15 minutes, and the waste tires are crushed. After the crushed waste tires are mixed with bentonite and calcium hardate, they are put into a ball mill and ground for 30 minutes. The temperature is kept at 55- 57°C, mixture 1 was obtained;

[0023] 2) After mixing the urea-formal...

Abstract

The invention discloses a plastic bag prepared from modified waste tire rubber powder. The plastic bag is prepared from linear low density polyethylene, the modified waste tire rubber powder, alpha-methylstyrene cyclic dimer, polyacrylamide, starch, rosin, acrylamide, C9 petroleum resin, biphenol acrylate and polyvinyl alcohol. According to the plastic bag prepared from the modified waste tire rubber powder, the waste tire resources can be well utilized, the natural environment is protected, the resource utilization rate is increased, and the plastic bag has the advantages of being low in energy consumption, small in pollution and low in protection cost. The longitudinal tensile strength of the plastic bag can reach 17.1 MPa, and the transverse tensile strength of the plastic bag can reach 16.2 MPa. The plastic bag is bright in gloss, good in transparency, high in bearing capability and capable of meeting the requirements of consumers for containing more articles and using repeatedly.

Description

technical field [0001] The invention relates to the field of plastic production, in particular to a plastic bag prepared from modified waste tire rubber powder. Background technique [0002] With the gradual improvement of people's living standards and the rapid development of the logistics industry, the number of private cars and trucks in my country has increased year by year. The increase in the number of vehicles has driven the development of the economy, and the consumption and wear of automobile tires has also produced a lot of garbage - waste tires. A few years ago, waste tires were thrown away as garbage, which greatly polluted the environment we depend on for survival. The waste tires produced in China are increasing at a rate of 8% to 10% every year. In 2010, China produced about 250 million waste tires, and the recycling rate was only about 15%, less than 50% of that in Western developed countries, resulting in a huge waste of resources.
