Description
Technical Field
The invention relates to a low-temperature-resistant anti-aging material and application thereof in preparation of outdoor letter and newspaper boxes.
Background
The mailbox is one of the matching products of newly-built communities and office buildings, is not only an important carrier for users to receive mails and various bills, but also is new along with the continuous upgrading and updating of products and the promotion of a surface treatment mode, and people are more and more inclined to use the mailbox as a decoration of buildings while meeting the functions. The mailbox is an important carrier for receiving mails and various bills by users, and the requirements on the material and the manufacturing process of the mailbox are higher and higher along with the continuous upgrading and upgrading of products, the difference of residential building styles and the improvement of building quality while the use function of the mailbox is met.
The materials of the letter and newspaper boxes undergo the development process from wood, iron sheet to stainless steel. The conventional letter and newspaper boxes are mostly made of stainless steel, so that the price is high, and the batch manufacturing is complicated. With the popularization of high-performance materials, some American customers put forward requirements, and American household letter and newspaper boxes are prepared by using high polymer materials instead of traditional metal materials. The mailbox made of the modified plastic material has lower price on the basis of meeting the requirements of low temperature resistance and ageing resistance, is directly formed in one step through injection molding, and has simple process. The outdoor mailbox material needs to have the advantages of low temperature resistance, impact resistance and outdoor aging resistance, and simultaneously needs to consider the low cost of the material, but the technical scheme which is thought to be solved is not provided at present.
