Abstract

The invention discloses a fiber reinforced foamed plastic preparation process, the fiber reinforced foamed plastic preparation process adopts a preparation device for preparation, the preparation device comprises a preparation box, and the top of the preparation box is provided with a raw material inlet and a short fiber particle inlet. According to the foamed plastic preparation process, air purification equipment is arranged on the preparation device, peculiar smell gas left in a box body is introduced into a filter box for purification treatment, the peculiar smell gas is effectively purified through three filtering modes, the foamed plastic is more environmentally friendly, meanwhile, a pushing discharging mode is adopted for foamed plastic subjected to foaming forming, the discharging speed is increased, and discharging automation is realized; and according to the foamed plastic preparation process, cooling equipment is arranged on the preparation device, flowing water transfers heat in a heat transfer mode, the cooling rate is effectively increased, and the whole preparation process is shortened.

Description

technical field [0001] The invention relates to the technical field of foamed plastics preparation, in particular to a fiber-reinforced foamed plastics preparation process. Background technique [0002] Foam plastic is a polymer material with plastic as the basic component and contains a large number of bubbles. It belongs to the composite plastic filled with gas. Compared with pure plastic, it has many excellent properties, such as light weight, high specific strength, and absorbability. Impact load, heat insulation and sound insulation are good, so it has been widely used in industry, agriculture, construction, transportation and other fields. [0003] The current production of foam plastics is mainly divided into two types, one is solution foaming molding, and the other is crystal foaming molding. The solution foaming is carried out by placing the plastic solution and related auxiliary materials in a foaming tank or a foaming box. Fusion, steam foaming, cooling and disch...
