Photodiffusion film with blue light shielding function

The invention relates to a photodiffusion film with a blue light shielding function. The photodiffusion film is composed of a base material layer, a photodiffusion layer and a blue light shielding layer, wherein the two surfaces of the base material layer are provided with the photodiffusion layer and the blue light shielding layer respectively. According to the photodiffusion layer, organic silicon resin spherical micro-powder is evenly dispersed in base materials, the thickness of the organic silicon resin spherical micro-powder is 5% - 20% of the thickness of the whole film, and the weight of the organic silicon resin spherical micro-powder is 0.5% - 2% of the total weight of the photodiffusion layer. According to the blue light shielding layer, blue light shielding particles are evenly dispersed in the base materials, the thickness of the blue light shielding particles is 5% - 20% of the thickness of the whole film, and the weight of the blue light shielding particles is 0.5% - 2% of the total weight of the blue light shielding layer. The photodiffusion film has the advantages of being high in haze, moderate in light transmittance, and good in stability of haze and light transmittance and has a blue light shielding function. Solutions are not used during photodiffusion film manufacturing, and therefore environmental friendliness is realized. Meanwhile, manufacturing technology is simple, price is low, application prospects are good, and market value is high.

Highly transparent polyethylene shrink film and film blowing technology thereof

The invention relates to the technical field of shrink films, in particular to a highly transparent polyethylene shrink film and a film blowing technology. The highly transparent polyethylene shrink film consists of three films, namely an outer layer, a middle layer and an inner layer; the outer layer comprises 0%-20% of LDPF, 79%-99% of MPE, and 1%-5% of a nucleating agent in percentage by weight; the melt index of LDPE in the outer layer is greater than or equal to 2g/10min, and the melt index of MPE is greater than or equal to 1g/10min; the middle layer comprises 60%-80% of MDPE, 10%-20% of LDPE and 10%-20% of HDPE in percentage by weight; the melt index of MDPE in the middle layer is smaller than or equal to 0.5g/10min, the melt index of LDPE is smaller than or equal to 0.5g/10min, and the density of HDPE is greater than or equal to 0.960g/cm<3>; and the composition of the raw material of the inner layer and the composition of the raw material of the outer layer are the same. The highly transparent polyethylene shrink film has the haze of 7%, the light transmittance of greater than or equal to 92%, and the glossiness of 75%, so that the haze is good, the glossiness is good, and a printed pattern is more attractive and clearer when the highly transparent polyethylene shrink film is used for printing. The film blowing technology is stable in condition, precise in temperature and high in production efficiency.

InactiveCN107022041AIncrease the degree of acetalizationStable structurePolyvinyl butyralPolymer science
The invention discloses high-viscosity polyvinyl butyral. The high-viscosity polyvinyl butyral is prepared from the following raw materials in parts by weight: high-polymeric polyvinyl alcohol, low-polymeric polyvinyl alcohol, pure water, ammonium sulfate, n-butanal and concentrated hydrochloric acid. The invention also discloses a preparation method of the high-viscosity polyvinyl butyral. The preparation method comprises the following steps: preparing a polyvinyl alcohol solution; adding n-butanal and concentrated hydrocholoric acid into the polyvinyl alcohol solution, thus obtaining primary high-viscosity polyvinyl butyral; and washing the primary high-viscosity polyvinyl butyral with pure water until the pH of the washing solution is 7, and then drying to obtain the high-viscosity polyvinyl butyral finished product. The high-polymeric polyvinyl alcohol and the low-polymeric polyvinyl alcohol of different polymerization degrees are adopted to prepare the high-viscosity polyvinyl butyral together with the pure water, the ammonium sulfate, the n-butanal and the concentrated hydrochloric acid, so that not only is the obtained product stable in structure and high in degree of acetalization, good in transparency and haze, but also the process is simple, easy in preparation and suitable for being popularized.
