Embodiment 1
[0055] The culture-specific film of the present embodiment is made up of the following components by weight:
[0067] The special film for farming in this embodiment has an optimized component formula, adding an appropriate amount of additives, effectively preventing atomization, and has good mechanical properties. Linear low-density polyethylene (LLDPE) is non-toxic, tasteless, odorless milky white particles with a density of 0.918~0.935g / cm3. Compared with LDPE, it has a higher softening temperature and melting temperature, an...
Embodiment 2
[0080] The main technical solution of this embodiment is basically the same as that of Embodiment 1, and the features not explained in this embodiment are explained in Embodiment 1, and will not be repeated here. The difference between this example and Example 1 is that the parts by weight of LLDPE are 20 parts by weight, the parts by weight of LDPE are 30 parts by weight, and the parts by weight of metallocene polyethylene are 30 parts by weight. The film performance test data of embodiment 2 is as table 2:

Embodiment 3
[0084] The main technical solution of this embodiment is basically the same as that of Embodiment 1, and the features not explained in this embodiment are explained in Embodiment 1, and will not be repeated here. The difference between this example and Example 1 is that the weight part of LLDPE is 40 parts, the weight part of LDPE is 40 parts, and the weight part of metallocene polyethylene is 35 parts. The film property test data of embodiment 3 is as table 3:

Abstract
The invention relates to a special cultivation film and a preparation method thereof. The special cultivation film is prepared from the following components in parts by weight: 20-40 parts of LLDPE, 30-40 parts of LDPE, 30-35 parts of metallocenepolyethylene, 3.5 parts of glycerin monostearate, 1.2 parts of fatty acidamide, 0.3 part of an antifogging agent, 5 parts of a light stabilizer, 10 parts of a PE anti-ageing agent, 3 parts of hydrotalcite, 0.1 part of an antioxidant and 1 part of polyphthalic diamide. By carrying out modified treatment on base materials LLDPE and LDPE by virtue of an optimized constitution formula, the special cultivation film with a good antifogging effect and excellent physical and mechanical properties is obtained. The preparation method of the special cultivation film has the advantages that the steps are simple and reasonable, and the prepared finished product can meet the mechanical strength requirements of antifogging special cultivation films.
Description
technical field [0001] The invention relates to the technical field of plastic films, in particular to a special film for breeding and a preparation method thereof. Background technique [0002] Using greenhouses for off-season aquatic product farming is similar to growing vegetables in greenhouses. They both use sunlight as heat preservation energy to maintain the temperature of the environment and water in the greenhouse. Compared with traditional farming methods, greenhouseaquatic product cultivation has obvious advantages and considerable economic benefits. It is considered to be a new way to develop aquatic product cultivation. However, the current plastic film cannot be well applied to the aquaculture industry, especially the aquaculture industry. [0003] Therefore, in view of the existing problems in the prior art, it is particularly important to urgently provide a breeding-specific membrane technology for the breeding industry. Contents of the invention [0004...
