Problems solved by technology

At present, there are mainly two types of commonly used engineering enclosures: metal enclosures and plastic enclosures. Although the former is relatively strong, it has high cost, heavy weight, long installation time and is easy to rust
Although the latter has a lower cost, it is prone to aging and deterioration, the application environment is narrow, and it is difficult to degrade, which will generate a lot of plastic waste
And these two fences are not beautiful. In recent years, there have been green fences. It is to paste the artificial turf on the original fence and then reinforce it with screws, so as to achieve the purpose of beautification. sharply increase the cost
At the same time, the main material of artificial green turf is polyethylene or polypropylene, which are easy to age and fade after being exposed to the wind and sun for a long time, and the service life is not long

Embodiment 1

[0053] Method for preparing process PVC enclosures by building discarding PVC, figure 2 As shown, including the following steps:

[0054] (1) Disconnect the discarded sugar canesets and bamboo slag bleach, mixed into the pulverizer into plant waste powder and put it on the sieve plate, and screen the particle diameter plant waste slag powder in 100 megadownload megadownload megadownload megadownload megadownload megadownload megadownload megadownload megadownload megadownload megadownload megadownload megadownload megadownload megadownload megadownload megadownload Plus water dilute the gum and the girder is 25 ° Sr.

[0055] (2) Remove the impurities of impurities, plasticizer, stabilizer, hollow glass micro-balls, etc., plasticizer, stabilizer, hollow glass micro-balls, etc., and in step (1), in the order of the first-solid retrorefluid, the temperature is 140 ° C, Mixing the high-speed mixer of 700R / min, mixed with each raw material, mix well after stirring for 15 min, and so...

Embodiment 2

[0064] As compared with Example 1, the gilt in step (1) was raised from 25 ° SR to 30 ° SR, and the other conditions remain unchanged.

Embodiment 3

[0066] Compared with Example 1, the mixture of the construction of the PVC, stabilizer, plasticizer, and hollow glass microbeads were transferred from 140 ° C to 150 ° C, and the other conditions remain unchanged.

Abstract

The invention relates to a technical PVC enclosure film and method prepared by using construction waste PVC. The technical PVC enclosure film is composed of a technical enclosure film sheet and a UV curable glue covering the surface of the technical enclosure film sheet. ; The technological barrier film sheet includes the following components in parts by weight: 100 parts of construction waste PVC, 3 to 5 parts of plant waste residue, 1 to 2 parts of hollow glass microspheres, 30 to 40 parts of plasticizer, heat stabilizer 1 to 3 parts, light stabilizer 0.2 to 0.4 parts; plant waste residues include discarded sugar cane bagasse and bamboo residue. Compared with the prior art, the technological PVC enclosure film of the present invention is low in cost, not easy to age and fade, easy to recycle, process and reuse, easy to transport, simple and convenient to install, saves manpower and material resources, and is green and environmentally friendly; it can be personalized according to different occasions Customized design, pattern, thickness, length, etc., can meet different needs. The application environment is extremely wide, and it has good development prospects and use space.

Description

Technical field [0001] The present invention relates to the field of recovery treatment of buildings, and more particularly to a process-based PVC peripheral membrane and method prepared by building discarded PVC. Background technique [0002] Since the 21st century, the urbanization process in China has failed, accompanied by the modernization of major cities, in addition to the rapid development of the building industry, there is a large amount of construction waste, which not only seriously affects the city, but also pollutes the environment. health. As common building materials, PVC is widely used in many fields such as doors and windows, pipes, packaging materials, and how to reasonably recycle to use their building waste garbage is also a topic that cannot be ignored. [0003] Of course, urbanization is also within the renewal of major construction sites to continue to build, with various engineering enclosure to isolate protection and reduce safety hazards. At present, the...
