Pink light conversion multi-functional heliogreenhouse film

Abstract

The invention discloses a pink light conversion multi-functional heliogreenhouse film, which is prepared from the following raw materials in percentage by weight: for the outer layer, 30-50% of LLDPE, 20-40% of LDPE, 20-30% of mLLDPE and 8-10% of multi-functional master batch; for the middle layer, 10-20% of LLDPE, 20-30% of LDPE, 30-40% of EVA, 13-15% of multi-functional master batch and 4-8% of pink fluorescence conversion master batch; for the inner layer, 25-35% of LDPE, 50-60% of EVA and 10-20% of multi-functional master batch, wherein the multi-functional master batch is prepared from the following raw materials in percentage by weight: 10-20% of LLDPE powder materials, 50-65% of EVA, 3-5% of hindered amine light stabilizer, 1.5-2.5% of anti-oxidant, 1.5-2.5% of ultraviolet absorbent, 10-15% of dripping agent, 3-4% of anti-fogging agent, 2-3% of thermal insulating agent and 1.5-2.5% of organic fluorescence conversion agent, the pink fluorescence conversion master batch is prepared from the following raw materials in percentage by weight: 10-20% of LLDPE power materials, 25-40% of EVA, 10-20% of LDPE, 1.5-2.5% of anti-oxidant, 3-5% of dispersant, 3-5% of lubricant and 30-40% of organic fluorescence conversion agent.

Description

technical field [0001] The invention relates to an agricultural greenhouse film, in particular to a pink light-converting multifunctional sunlight greenhouse film. Background technique [0002] In the plastic film of the prior art, the colorless light-transforming agent has no color specificity to crops and sunlight, and the red-orange light transmittance required for photosynthesis of crops is low; the inorganic light-transforming agent decays quickly and has a short duration , only about 30 days; while the colored organic light-changing agent used in polyester, polyvinyl chloride and other resins has a single-layer blend structure, the product has few functions, and the function has a short duration. It is only used for packaging films and cannot be used for making plastics. Greenhouses and Greenhouses. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pink light conversion multifunctional solar greenhouse fil...
