  • Patent number: 10494514
    Abstract: The present disclosure involves a preparation method of bio-based silica/poly (itaconate-ter-isoprene-ter-glycidyl methacrylate) nanocomposite. Bio-based silica/poly (itaconate-ter-isoprene-ter-glycidyl methacrylate) nanocomposite is environment-friendly, and silica and poly (itaconate-ter-isoprene-ter-glycidyl methacrylate) are derived from non-petroleum base materials, which do not rely on fossil fuel. Compared with nanocomposite without nanocomposite, nanocomposites with glycidyl methacrylate have better silica diffusion, mechanical properties and wet-skid resistance of rubber product are improved while consuming the same time. Further, rolling resistance is decreased so that using silane coupling agent is avoided. Therefore, the processing technology is simplified, and VOC emission is avoided. It is a kind of “green tire” rubber product.

  • Patent number: 8927628
    Abstract: A method for fabricating energy plastic masterbatches and a plastic product containing energy plastic masterbatches fabricated by the method are provided. The fabrication method includes: oxidizing carbon black with ozone; fully mixing carbon black after treatment and a nano tourmaline powder to form a base; adding ultrafine rutile titanium dioxide to the base, and mixing fully, to form an energy raw material; drying the mixed energy raw material at 100-120° C.

  • Patent number: 8810781
    Abstract: A detection device is described for measuring the vaporization-melt ratio, the device including a light source, a first and second optical lens group, a slit, a first and second steering mirror, a first and second primary mirror, a glass container, a colored blade, and a high-speed recording analyzer. The first primary mirror and the second primary mirror are symmetrically placed at both ends of the glass container. The first optical lens group is located between the light source and the slit. The second optical lens group is located between the colored blade and the high-speed recording analyzer. The first steering mirror is installed behind the slit, passing the light from the slit to the first primary mirror. The light reflected by the second primary mirror is passed to the colored blade from the second steering mirror located between the second primary mirror and the colored blade.

  • Publication number: 20120200848
    Abstract: A detection device for measuring the vaporization-melt ratio, the device including a light source, a first and second optical lens group, a slit, a first and second steering minor, a first and second primary minor, a glass containers, an object, a colored blade, and a high-speed recording analyzer. The first and second primary mirror is symmetrically placed at both ends of the glass container. The first optical lens group is located between the light source and the slit. The second optical lens group is located between the colored blade and the high-speed recording analyzer. The first steering mirror is installed behind the slit, passing the light through the slit to the first primary mirror. The light reflected by the second primary mirror is passed to the colored blade through the second steering minor located between the second primary minor and the colored blade.
