Embodiment 1

[0070] Such as figure 1 , figure 2 and image 3 Shown, a kind of production equipment based on CaCO3 nano-SiO2 modified HDPE furniture materials, including banburying device 1, die set 2, cooling tank 3 and screw conveyor 4, said die set 2 is arranged on said close On the refining device 1, and it is located at the feed end of the cooling tank 3, the strip material 5 formed by the die set 2 is conveyed in the cooling tank 3, and the screw conveyor 4 is arranged on the internal mixing One side of the device 1, the discharge end of the screw feeding pipe 51 at the bottom is arranged directly above the feed hopper 11 of the banburying device 1, and also includes:

[0071] The dense cooler 6, the dense cooler 6 is arranged at the feeding end of the cooling tank 3, which includes cooling machines 61 arranged on both sides of the cooling tank 3 and arranged in sequence along the feeding direction of the cooling tank 3 The pre-cooling pipe 62, the dense cooling mechanism 63, and ...

Embodiment 2

[0122] Reference Example 1, a production process based on CaCO3 nano-SiO2 modified HDPE furniture material.

[0123] Such as Figure 17 Shown, a kind of based on CaCO Nano SiO The production technique of the HDPE furniture material of modification, it is characterized in that, comprises the following steps:

[0124] Step 1, the mixing process, the modifier and raw materials are poured into the hopper 42 for mixing, and after mixing evenly, the screw feeding pipe 51 located below the hopper 42 is lifted and transported to the feeder of the banburying device 1 located on the side of the hopper 42. Inside the hopper 11;

[0125] Step 2, banburying process, the mixture of modifier and HDPE input into the feed hopper 11 is smelted by the banburying device 1, and the strip material 5 is formed by the output of the die set 2 after smelting;

[0126] Step 3, pre-cooling process, after the formed strip material 5 is input into the cooling tank 3, it is transported along the length dire...

Abstract

The invention provides production equipment and a process for an HDPE furniture material based on CaCO3 nano SiO2 modification. The equipment comprises a banburying device, a mold head assembly, a cooling trough, a spiral conveyor, a compact cooler and a stirring device. The inflowing speed and the outflowing speed of a cooling agent in a cooling pipe, a first stirring bag and a second stirring bag in the using process are controlled, the cooling pipe is made to expand to extrude and compact a formed material so that the design can be improved, and the first stirring bag and the second stirring bag expand to stir and preheat raw materials. Meanwhile, the process comprises the procedures of mixing, banburying, precooling, cooling, gradual cooling and pelletizing. The raw materials are preheated and stirred through liquidity of the cooling agent before being subjected to banburying, the formed strip-shaped materials are cooled and extruded through the precooling procedure and the extruding and cooling procedure after the forming procedure is carried out, and the technical problem about density and mixing uniformity in the modification process of the HDPE furniture material are solved.

Description

technical field [0001] The invention relates to the technical field of preparation of injection molding and spray molding furniture raw materials, in particular to a production equipment and process of HDPE furniture materials based on CaCO3 nano-SiO2 modification. Background technique [0002] Plastic furniture is a new type of furniture, which has played an important role in people's daily life. Compared with other furniture, plastic furniture has the advantages of 1) brilliant colors and smooth lines; 2) diverse and casual and beautiful shapes; 3) light and compact, easy to take; 4) various varieties and wide application; 5) easy to clean and easy to protect; 6) cheap And so on a series of advantages. Because plastic furniture has such obvious advantages, it has rapidly occupied the market share in the furniture field in recent years. But at present, my country's domestic plastic furniture mainly occupies the middle and low-end market in the mainstream furniture market....
