摘要： In accordance with the present invention, there is provided a light diffusion sheet provided with a light diffusion layer formed in a same sheet, comprising a light diffusion sheet made of a light transmitting material and including a plurality of layers; a light diffusion layer to constitute at least one layer among the plurality of layers of the light diffusion sheet in which a plurality of pores are distributed by foaming; and a light transmitting layer as a layer different from the light diffusion layer of the plurality of layers of the light diffusion sheet in which any pore is not distributed, wherein each of the plurality of layers of the light diffusion sheet is discriminated from each other in the same sheet by foaming and when the light diffusion layer is plural, the average size of pores in the light diffusion layers disposed close to a light source is equal to or larger than the average size of pores in the light diffusion layers disposed far from the light source and the average density of the pores in the light diffusion layers disposed close to the light source is equal to or lower than the average density of the pores in the light diffusion layers disposed far from the light source.

摘要： The present invention relates to a production method for a splash shield using a continuous extrusion-injection-foaming moulding process, and more specifically relates to a method for producing a splash shield, in which method a base-portion raw material comprising a plastic, glass fibres, a compatibilizer and rubber is subjected to melt extrusion while at the same time injection moulding is carried out, and then, without removing the injection-moulded article from the injection mould, the injection mould is rotated in the open state, and the injection-moulded article is conveyed to a foaming mould and subsequently undergoes a flame treatment and a polyurethane foam moulding step. In the production method for a splash shield according to the present invention, a single process is used for the procedure in which the materials are separately compounded and pelletized and the procedure in which the injection-moulded article is moulded and a foamed body is moulded, and thus it is possible to curtail the conveying of materials and various component parts and to reduce the risk of moulding dimension errors and of denaturing and contamination in the conveying procedure.
摘要翻译：本发明涉及一种使用连续挤压注射发泡成型工艺的防溅罩的制造方法，更具体地说涉及一种防溅罩的制造方法，其中，将包含塑料，玻璃纤维，增容剂和橡胶进行熔融挤出，同时进行注射成型，然后，在不从注射模具中取出注射成型制品的情况下，注射模具在打开状态下旋转，并且注射模塑制品被输送到发泡模具中，随后进行火焰处理和聚氨酯泡沫模制步骤。在根据本发明的防溅罩的制造方法中，使用单一方法，其中将材料分别复合并造粒，并且注塑模制品被模制的步骤和模制泡沫体，因此可以减少材料和各种部件的输送并降低成型尺寸误差和输送过程中变性和污染的风险。
