Abstract

[목적][purpose]

본 발명은 사출기 등의 사출성형기에 의해 소요제품을 제조하는 사출성형원료를, 펄프섬유를 주성분으로 하고 여기에 열가소성 수지를 혼합하여 거친 분말 또는 펠릿화하므로서 사출성형물의 경량화, 폐품의 소각 처리가능화, 원료의 염가화 등을 구현할 수 있는 합성수지가 결합된 섬유질 사츨성형재 및 그 제조방법을 제공하기 위한 것이다.The present invention is an injection molding raw material for producing a required product by an injection molding machine such as an injection molding machine, the pulp fiber as a main component and the thermoplastic resin is mixed with the coarse powder or pelletized to reduce the weight of the injection molding, and to enable the incineration treatment of waste products In order to provide a fibrous bushing molding material and a method for manufacturing the same, in which a synthetic resin capable of realizing a low cost of a raw material is combined.

[구성][Configuration]

열가소성 수지를 전체량의 10~49중량%, 고지류를 풀어서 얻은 펄프섬유를 전체량의 90~51중량%로 배합한 원료로 하고, 이 원료를 5㎜ 정도 크기의 거친 분말 또는 펠릿화하며, 이것을 열가소성 수지의 1차 전이점 온도이상에서 발생하는 가열면에 접촉시키면서 굴려서 펠릿의 외주면으로 돌출되는 섬유단말지를 해소하는 것을 특징으로 한다.　10 to 49% by weight of the total amount of thermoplastic resin and pulp fibers obtained by loosening the high paper are blended into 90 to 51% by weight of the total amount, and the raw material is coarse powder or pelletized about 5 mm in size. It is characterized in that the fiber terminal is rolled out while contacting the heating surface generated above the primary transition point temperature of the thermoplastic resin to protrude to the outer peripheral surface of the pellet.
