Problems solved by technology

In the case where the polypropylene resin raw material is the main raw material and the filler masterbatch is the auxiliary raw material, its dispersion and plasticizing effects are not stable
In addition, in the printing process, the ink printing process is difficult to achieve the effect of traditional cartons. The resin content of the calcium-plastic box is too high, the ink absorption is poor, the quick-drying time is long, the output is low, and it is easy to fall off. Therefore, although the calcium-plastic box is waterproof and moisture-proof , compression resistance, shock resistance, oil stain resistance, corrosion resistance, etc., but the hand feeling is average, it is not easy to fold the box, the printing tone pattern is single, it is easy to become brittle, the tearing of the corners is poor, the cost is high, and it is uneconomical. With the price of polypropylene resin raw materials fluctuations, cost control is unstable, and the market price is more than 2 times higher than that of traditional cartons

preparation example Construction

[0046] The embodiment of the present invention also provides a method for preparing the modified masterbatch of stone-plastic box according to the above-mentioned embodiment, comprising the following steps:

[0047] Mix nano-calcium carbonate and nano-talcum powder in a high-speed mixer in parts by weight, and fully dry the moisture in the mixed material powder to obtain material 1 when the temperature reaches 105°C;

[0048] Add a coupling agent to material 1, mix and stir for 2-3 minutes, and wait until the temperature reaches 110-115°C to obtain material 2;

[0049] Add toughening agent POE and lubricant to material 2, mix and stir for 1-3 minutes, and wait until the temperature reaches 110-115°C to obtain material 3;

[0050] Add composite modified high fat-soluble polypropylene resin, polypropylene copolymer resin, and polypropylene homopolymer resin to material 3, mix and stir for 5-7min, and wait until the temperature reaches 120-140°C to obtain material 4;

Abstract

The invention provides a modified master batch of stone-plastic box, its preparation method and the obtained product, which belong to the technical field of modified materials. The stone-plastic case modified masterbatch is prepared from the following components by weight: 40-50 parts of nano-calcium carbonate, 20-30 parts of nano-talc powder, 0.5-2 parts of composite modified high-fat-soluble polypropylene resin, polypropylene 10-16 parts of propylene copolymer resin, 3-5 parts of polypropylene homopolymer resin, 0.3-1.5 parts of coupling agent, 5-10 parts of toughening agent POE and 1-3 parts of lubricant. After the stone-plastic box modified masterbatch provided by the invention is added to the stone-plastic box, on the one hand, the strength, toughness, compression resistance, shockproof, tear resistance and easy molding functions of the stone-plastic box are greatly improved. On the one hand, the waterproof, moisture-proof and fresh-locking functions of the stone-plastic box are improved. The stone-plastic box made by using the stone-plastic box modified masterbatch provided by the invention can effectively replace the traditional corrugated box, not only has low economic cost, strong function, but also is environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of modified materials, and in particular relates to a modified masterbatch of stone-plastic box, its preparation method and the obtained product. Background technique [0002] Due to the limited forest resources in our country, the output of pulp cannot meet the needs of use, and when using pulp to produce cardboard, the process is complicated, and the resource and energy consumption is large. Water, electricity, fuel and virgin wood pulp need to be added according to the process requirements. Therefore, The environmental and energy problems in cardboard production have become serious social problems. Traditional cartons are not waterproof, not moisture-proof, have poor compression resistance, poor tearability, and poor freshness locking effect. Therefore, a plan to replace traditional cartons with stone-plastic boxes is proposed. [0003] Stone-plastic boxes can have the advantages of environmental protect...
