Embodiment 1

[0029] Raw material formula (percentage by weight):

[0030] Polyolefin (LDPE-N150) 45%

[0031] Sericite (ultrafine treated with titanate activation) 30%

[0032] Light stabilizer (Chimassorb 944) 2%

[0033] Heat stabilizer (Irganox 900) 2%

[0034] Oxidizing agent (Irganox 7072) 2%

[0035] Anti-drip agent (ATF-2) 15%

[0036] Dispersant (WAX-3) 4%

[0037] The method of sericite activation is to pour sericite and titanate (or aluminate) into the high-speed mixer successively, the stirring speed is 900-960rpm, the temperature is 80-100°C, the stirring time is 10min, and then deflate, Just take the material.

[0038] The preparation method of the modified masterbatch of the multi-functional agricultural greenhouse is to pour the raw materials of the above formula into the high-speed mixer one after another, control the stirring speed at 450-480rpm, and stir for 3-5 minutes, then do the shoveling, shoveling and discharge water vapor Wait for the operation, then control...

Embodiment 2

[0040] Raw material formula (percentage by weight):

[0041] Polyolefin (LDPE-N200) 40%

[0042] Sericite (ultrafine treated with aluminate activation) 35%

[0043] Light stabilizer (HA88) 1%

[0044] Heat stabilizer (Irganox 900) 1%

[0045] Antioxidant (Irganox 7072) 2%

[0046] Anti-drip agent (ATF-2) 18%

[0047] Dispersant (WAX-3) 3%

[0048] The manufacturing method is the same as in Example 1.

Embodiment 3

[0050] Raw material formula (weight fraction):

[0051] Polyolefin (LDPE-N200) 50%

Abstract

The invention relates to a modified master batch used in a multifunctional agricultural greenhouse, which is made by activating, stirring, mixing and screening polyolefin, sericite, a light stabilizer, a heat stabilizer, an antioxidant, an anti-flow-dripping agent and a dispersant. The modified master batch of the invention can improve the tensile strength of plastics, strengthen the toughness of products and resist aging and cracking. As to reinforced thermoplasticity plastics, the modified master batch is characterized by high strength, large filling volume, good acid-base corrosion resistance, penetration and dielectric property, low thermal expansion coefficient and flammability, short period of transverse compression, planar enhancement, low abrasion and low wear of processing equipment; as to reinforced thermosetting plastics, the modified master batch has good dielectric property, good size stability, improved hardness and heat distortion temperature as well as good penetration and insulation. In addition, the modified master batch also has good dissolubility and can be compatible with a great deal of fillers such as talcum powder, calcium carbonate, etc.

Description

technical field [0001] The invention relates to polymer material raw materials, in particular to a modified masterbatch for multifunctional agricultural greenhouses and a manufacturing method thereof. Background technique [0002] The existing agricultural greenhouse films are generally made of polyolefin materials. Due to the limitations of the tensile strength, flexibility, high temperature resistance and acid and alkali resistance of this film, as well as the limitations of thermal insulation performance and weather resistance, etc., The variety and quality of horticultural products cannot be used to meet higher requirements. Contents of the invention [0003] The object of the present invention is to provide a modified masterbatch for multifunctional agricultural greenhouses with good thermal insulation and weather resistance and high tensile strength in order to overcome the defects in the prior art. [0004] A modified masterbatch for multifunctional agricultural gr...
