Embodiment 1

[0036] EPS foam molding device, such as Figure 1-Figure 7As shown, it includes a material reaction device, and the material reaction device includes a reaction housing 102 with a reaction chamber 101 inside. The middle part of the outer surface of the upper top plate of the reaction housing 102 is fixed with a bottom that communicates with the inside of the reaction chamber 101, and the upper end is open. The first cylindrical connection seat 103, the middle part of the inner surface of the upper top plate of the reaction housing 102 is fixed with the first connection seat 103 opposite to the first connection seat 103 and the upper and lower ends are open cylindrical second connection seat 104, also includes a sliding column 105 arranged in the first connecting seat 103 and can slide down to the second connecting seat 104 along the inner wall of the first connecting seat 103, the upper end of the sliding column 105 is located on the outer side wall of the sliding column 105 A...

Embodiment 2

[0050] EPS foam forming process is characterized in that it adopts the EPS foam forming device in embodiment 1, which comprises the following steps:

[0051] Step 1, polystyrene resin is carried out pretreatment, specifically comprises the following steps:

[0052] Step 1 put polystyrene resin into the reaction chamber 101 of the material reaction device, pass CO2 into the reaction chamber 101 of the material reaction device through the CO2 inlet passage 116 of the air inlet pipe 114 and feed into the reaction chamber 101 through the feed pipe 113 Adding an antistatic agent, wherein the antistatic agent is dodecyl dihydroxypropyl methyl ammonium sulfate, to obtain modified EPS beads;

[0053] Step 2 Add titanate and calcium carbonate powder into a high-mixer at a mass ratio of 1:3 for mixing, keep warm at 100-120°C for 1-2h, then add neodymium oxide, and stir at 80-90°C for 0.5-1h , to obtain a mixed solution; the mixed solution contains calcium carbonate, which can improve t...

Abstract

The present invention relates to an EPS foam material, and discloses an EPS foam material molding device and process, which includes a material reaction device and includes the following steps: step 1, pre-foaming polystyrene resin, and step 2, performing aging treatment , transport the pre-released EPS beads into the curing bin for curing; step 3, forming treatment, extract the matured EPS beads to the molding machine, then fill them into the mold, and inject steam to expand the EPS beads to obtain Shaped products. The present invention performs antistatic treatment on polystyrene resin through a specially designed reaction device, so that the finally prepared EPS foam material has longer-lasting and more efficient antistatic performance than existing products.

Description

technical field [0001] The invention relates to an EPS foam material, in particular to an EPS foam material molding device and process. Background technique [0002] EPS foam material is a kind of dismantling material used to produce EPS foam packaging products. It has the functions of cushioning and shock absorption, and also has the functions of heat preservation and heat insulation. It is currently a high-quality packaging protection material and is widely used in household appliances, Electronics, machinery, handicrafts, medicine, construction and decoration industries. [0003] The whole molding process of EPS foam material generally includes the steps of raw material preparation, pre-foaming treatment, aging treatment and molding treatment. The aging warehouse and the forming machine in the forming stage, etc. [0004] At present, the raw material preparation stage of the existing EPS foam material is generally only a simple treatment. Due to the good electrical insu...
