Abstract

The invention discloses a preparation method of a shopping bag handheld bag carrying device with better elasticity and comfort. The preparation method comprises the steps of weighing butadiene styrenerubber and a compounding agent, wherein according to the mass fraction, 55.5 parts of compounding agent is added during rubber refining; then drying, cutting, plastifying and mixing the butadiene styrene rubber; and finally putting an obtained rubber compound into an injection-compression molding machine, injecting the rubber compound into runners on the left side and the right side of a mold, and curing for molding at the temperature being 180 DEG C and the pressure being 5 to 8 MPa for 8 to 10 minutes. The preparation method provided by the invention is simple in process and high in production efficiency; and the prepared elastic handheld bag carrying device is good in elasticity, good in comfort, long in service life, light in weight and easy to carry. The elastic handheld bag carryingdevice is cured into a comfortable shape. The tensile strength of the elastic handheld bag carrying device reaches to 25.4MPa minimally, the wear resistance reaches to 0.16cm<3> / 1.61km maximally, theshape of the elastic handheld bag carrying device provided by the invention conforms to ergonomics, and the elastic handheld bag carrying device is comfortable to use.

Description

technical field [0001] The invention relates to the field of shopping bag bag carriers, and relates to a preparation method of an elastic hand-held bag carrier. Background technique [0002] Plastic bag is the most used packaging item in the shopping process. It is a portable daily necessities. It is widely used because of its convenient use, light weight and low price, allowing people to carry more items at one time when shopping. But when the article in the plastic bag is heavy, use for a long time can cause strangulation to make the blood unimpeded difficulty. In order to solve this problem, bag carriers began to appear. Most of the bag carriers in the domestic market are made of metal and are not convenient to carry. This kind of bag carrier is not easy to bend when in use, and it is easy to scratch shopping bags or hands. After being bent, it cannot be easily restored to the state before use. Once the shopping bag is under heavy load, it will strangle hands and prevent...
