Embodiment 2

[0032] The steps of this embodiment are as follows:

[0033] S1: Disperse nano-zinc stannate in ethyl acetate solvent, configure a mixed dispersion with a mass fraction of 20%, then add 5% dispersant BYK110, put it into a grinder, and grind it through a high-speed grinder until the particle size is at 50nm, stop grinding, and discharge to obtain a nano-slurry with a solid content of 20%.

[0034] S2: Disperse nano-indium tin oxide in ethyl acetate solvent, configure a mixed dispersion with a mass fraction of 20%, then add 5% dispersant BYK110, put it into a grinder, and grind it through a high-speed grinder until the particle size is 50nm, stop grinding, and discharge to obtain a nano-slurry with a solid content of 20%.

[0035] S3: 15 parts of nano-zinc stannate slurry obtained from S1 and S2, 15 parts of nano-tungsten indium tin oxide, 50 parts of polyethylene terephthalate, 18 parts of PEN resin, 2 parts of phosphate flame retardant Parts were mixed in a high-speed mixer ...

Abstract

The invention discloses a hardened flame-retardant heat-insulating master batch and a production method therefor. The hardened flame-retardant heat-insulating master batch is prepared from the following raw materials in parts by weight: 50-70 parts of support resin polyethylene terephthalate (PET), 20-30 parts of polyethylene naphthalate (PEN), 5-10 parts of flame retardant, 5-10 parts of heat-insulating auxiliaries and 5-10 parts of dispersant. According to the hardened flame-retardant heat-insulating master batch and the production method therefor, after the PET master batch is added into aPET material product, a flame retardant rating of an obtained PET product can reach a level V0 (UL94), meanwhile, the infrared ray barrier rate reaches 60% to 99% (changing along with an addition level), and the influence on light transmittance of the product is relatively low. The PET master batch disclosed by the invention is prepared through subjecting various additives and the PET resin to mixing granulation, the preparation process is simple, and the cost is relatively low. The PEN resin is added into a formula of the PET master batch, so that mechanical properties and barrier performanceof the product can be improved, and thus, the field of application of the PET product is enlarged.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a hardened flame-retardant and heat-insulating masterbatch and a manufacturing method thereof. Background technique [0002] With the upgrading of people's consumption, many people will stick films on the glass of cars and buildings to achieve the purpose of heat insulation and sun protection. Existing heat-insulating films are generally composed of multi-layer films with different functions, and their effects are not satisfactory. In case of a fire hazard, the heat-insulating films will burn immediately at first and bring great losses to people's lives and property. At present, the existing patents are all realized by multi-layer coating or co-extrusion. This method has the problems of easy peeling off of the coating, high production cost, and large pollution. [0003] Prepare flame retardant and heat insulation masterbatch first, which can better solve the problems e...
