Problems solved by technology

[0004] For the above-mentioned related technologies, the inventor believes that there are the following defects: since the limiting oxygen index of PLA in the air is only 14%-15%, it is extremely flammable, and when an open flame is caused by a short circuit of an electrical device, its external PLA protective cover is easy to burn. Combustible, easy to expand the fire, a fire safety hazard

Embodiment 1-5

[0034] The following is illustrated by taking Example 1 as an example. The degradable PLA material used for the data line protective sleeve includes the following steps:

[0035] Raw material drying: bake the PLA masterbatch at 70°C for 10 hours, and bake the starch at 50°C for 10 hours to obtain dry PLA masterbatch and starch;

[0036] Melt blending: weigh each raw material according to Table 1, melt and blend each raw material for 15 minutes, and the melting temperature is 170°C to obtain a blend; extrusion granulation: crush the blend and put it into an extruder to melt and extrude out, and then cutting and granulating to obtain a degradable PLA material for the data cable protective cover, with a particle size of 2-4mm; the extruder has 4 temperature ranges from the feed port to the discharge port, and the temperature in each range The temperature from the feed inlet to the discharge outlet is 150°C, 155°C, 160°C, and 170°C respectively, and the temperature near the feed i...

Embodiment 6-11

[0042] As shown in Table 2, compared with Example 5, the main difference of the degradable PLA material used for the data line protective sleeve of Examples 6-11 is that the raw materials have increased resorcinol bis (diphenyl phosphate), At least one of hydroquinone bis(diphenyl phosphate) or hydroquinone bis[bis(1-methyl-2-phenyl phosphate)].

Embodiment 6

[0043] The difference between the preparation method of embodiment 6 and the preparation method of embodiment 5 is that in the melt mixing process, according to the difference between resorcinol bis(diphenyl phosphate) and hydroquinone bis(diphenyl phosphate) And the weight ratio with ammonium polyphosphate is that 1:1 has added resorcinol bis(diphenyl phosphate) and hydroquinone bis(diphenyl phosphate); The preparation method of embodiment 7 is the same as that of embodiment 5 The difference of the preparation method is that during the melt mixing process, the weight ratio of resorcinol bis(diphenyl phosphate) to ammonium polyphosphate is 1:2, adding resorcinol bis(diphenyl phosphate) ); the preparation method of embodiment 8-9 is the same as embodiment 7; the difference between the preparation method of embodiment 10 and the preparation method of embodiment 5 is that in the melt mixing process, press hydroquinone bis[two (1- The weight ratio of methyl-2-phenyl phosphate)] an...

Abstract

The invention relates to the technical field of PLA modified materials, and particularly discloses degradable PLA for a data line protection sleeve and a preparation method of the degradable PLA. The degradable PLA for the data line protection sleeve is prepared from the following raw materials in parts by weight: 800 to 900 parts of PLA master batch, 100 to 200 parts of starch, 50 to 100 parts of a flame retardant, 10 to 20 parts of a silane coupling agent, 10 to 20 parts of a light stabilizer and 10 to 20 parts of a lubricant. The preparation method comprises three steps of raw material baking, melt blending and extrusion granulation. The degradable PLA for the data line protection sleeve prepared by the invention has good flame-retardant and smoke-suppression performance and biodegradation rate.

Description

technical field [0001] The application relates to the field of data line protective sleeves, more specifically, it relates to a degradable PLA material for data line protective sleeves and a preparation method thereof. Background technique [0002] With the development of society and the improvement of people's awareness of environmental protection, people's demand for degradable and environmentally friendly plastics is also increasing. More and more fields have begun to use degradable and environmentally friendly plastics as the first choice for product materials. Commonly used degradable and environmentally friendly plastics include poly-3-hydroxyalkanoate (PHA), polylactic acid (PLA), poly-ε-caprolactone (PCL) and polybutylene succinate (PBS). [0003] Polylactic acid (PLA), also known as polylactide, is a polyester polymer obtained by polymerization of lactic acid as the main raw material. It is a new type of biodegradable material. As one of the environmentally friend...
