Problems solved by technology

[0003] Most of the pearl cotton on the market is pearl cotton with added grease. Under high temperature conditions, grease will leak out, which will cause certain pollution to the packaged items. Especially in the electronic field, most of them use foaming materials to replace the original pure plastic Packaging paper, the original plastic packaging paper cannot effectively absorb the grease produced on the surface of electronic products, resulting in a lot of grease and dust remaining on the surface of electronic products, which affects the appearance of electronic products

Embodiment 1

[0034] Embodiment 1: full degreasing pearl cotton, its preparation raw material comprises by weight: 100 parts of polyethylene, 10 parts of titanate modified calcium carbonate, 1 part of talcum powder, 1 part of silane coupling agent; 10 parts of modified VAE emulsion , 3 parts of degreasing masterbatch, 3 parts of antistatic masterbatch, 10 parts of foaming agent.

[0035] In the present invention, in a specific embodiment, polyethylene can be conventional polyethylene pellets used to prepare pearl cotton materials in the art, and the melt index of polyethylene pellets generally used to prepare pearl cotton materials is between 1.8 and 1.8. 7g / 10min; polyethylene pellets can be purchased from Saudi Arabia (Arabia) product FT4119, product 2420E02 from Iran Petrochemical, product 2420 from Yamba, product 2023NN from Sabic or product 450E from Dow.

[0036] The present invention preferably mixes polyethylene particles, degreasing masterbatches, antistatic masterbatches, etc. in ...

Embodiment 2

[0054] Fully defatted pearl cotton, its preparation raw materials include by weight: 155 parts of polyethylene, 19 parts of titanate modified calcium carbonate, 3 parts of talc powder, 3 parts of silane coupling agent; 15 parts of modified VAE emulsion, degreasing masterbatch 10 parts, antistatic masterbatch 10 parts, foaming agent 20 parts.

[0055] The modified VAE emulsion includes the following materials in parts by weight: 59 parts of VAE, 7 parts of polyvinyl alcohol, 20 parts of vinyl acetate, 4 parts of ammonium persulfate, and 3 parts of potassium persulfate.

[0056] A kind of preparation method of full degreasing pearl cotton, comprises the following steps:

[0057] Step (1), batching, dry 3 parts of talcum powder and 19 parts of titanate-modified calcium carbonate, pass through a 100-150 mesh sieve, add to a high-speed mixer, and set the temperature at 110-120°C at a speed of 500-1000rpm Stir and mix for 20-30min, then add 3 parts of silane coupling agent and blen...

Embodiment 3

[0067] The content of this example is basically the same as that of Example 1, and the content of the same part will not be repeated. The difference from Example 1 is that the raw materials for the preparation of fully defatted pearl cotton in this example include: 100 parts of polyethylene, titanic acid 10 parts of ester modified calcium carbonate, 1 part of talcum powder, 1 part of silane coupling agent; 10 parts of modified VAE emulsion, 6 parts of degreasing masterbatch, 5 parts of antistatic masterbatch, and 10 parts of foaming agent.

[0068] The modified VAE emulsion includes the following materials in parts by weight: 59 parts of VAE, 7 parts of polyvinyl alcohol, 20 parts of vinyl acetate, 4 parts of ammonium persulfate, and 3 parts of potassium persulfate.

[0069] Different from Example 1, in this solution, the parts by weight of the degreasing masterbatch are adjusted from 3 parts to 6 parts; the parts by weight of the antistatic masterbatch are adjusted from 3 part...

Abstract

The invention relates to fully-degreased pearl wool and a preparation method thereof. The fully-degreased pearl wool is prepared from the following raw materials in parts by weight: 100-155 parts of polyethylene, 10-19 parts of titanate modified calcium carbonate, 1-3 parts of talcum powder, 1-3 parts of a silane coupling agent, 10 to 15 parts of a modified VAE emulsion, 3 to 10 parts of degreasedmaster batch, 3 to 10 parts of antistatic master batch and 10 to 20 parts of a foaming agent, wherein the foaming agent is butane. According to the invention, polyethylene particles, the degreased master batch, the antistatic master batch and the like are preferably selected and mixed according to a certain ratio, a certain amount of butane gas is introduced to prepare the fully-degreased pearl wool; and compared with common pearl wool directly added with monoglyceride, the phenomenon of grease exosmosis on the surface of the pearl wool is reduced.

Description

technical field [0001] The invention belongs to the technical field of pearl cotton, and in particular relates to a fully defatted pearl cotton and a preparation method thereof. Background technique [0002] EPE pearl cotton has a non-cross-linked closed-cell structure. It is a high-foam polyethylene product extruded from low-density polyethylene (LDPE) as the main raw material. It is also called polyethylene foam cotton. It is a new type of environmentally friendly packaging material. Because it is composed of numerous independent bubbles produced by physical foaming of low-density polyethylene resin, it overcomes the shortcomings of ordinary foam rubber such as fragility, deformation, and poor recovery, and has good water and moisture resistance, shock resistance, sound insulation, heat preservation, and good plasticity. , Strong toughness, recycling, environmental protection, strong impact resistance, etc., also has good chemical resistance. [0003] Most of the pearl co...
