Plastic foamed sheet with antistatic and flame-retardant functions and manufacturing technique thereof

Abstract

The invention relates to an environment-friendly plastic foamed sheet with antistatic and flame-retardant functions and a manufacturing technique thereof. The manufacturing technique comprises the following steps: preparing bamboo carbon powder, kaolin, plastic, antistatic agent, flame retardant and other chemical assistants, banburying, mixing, discharging from a guillotine to obtain a sheet semi-finished product, and foaming to form with a foaming machine. The plastic foamed sheet is prepared from the following raw materials in parts by mass: 5.5-6 parts of plastic, 1.0-1.5 parts of bamboo carbon powder, 1.5-3.5 parts of kaolin, 1.0-2.5 parts of antistatic agent, 1.5-3.5 parts of flame retardant and 0.5-1.0 part of chemical assistants. The manufacturing technique produces the plastic foamed sheet with high-standard antistatic and flame-retardant functions, overcomes the defects and shortcomings in the prior art, has important and profound significance for solving the problems above, and has very wide market potential.

Description

Technical field: [0001] The invention relates to a plastic foamed board, in particular to an environmentally friendly plastic foamed board with antistatic and flame-retardant functions and a manufacturing process thereof. Background technique: [0002] Existing plastic foam sheet materials include: ethylene-vinyl acetate copolymer, POE elastomer plastic, high-pressure low-density polyethylene, low-pressure high-density polyethylene, high-low pressure composite polyethylene and other plastics, as well as antistatic agents, flame retardants, etc. Agents, chemical additives, calcium carbonate fillers, etc., the use of the above materials to produce plastic foam sheets with two high-efficiency antistatic and flame retardant effects is not ideal. There are four main defects: First, the material is difficult to decompose, because in order to achieve good antistatic and flame retardant effects, the amount of antistatic agent and flame retardant must be increased, resulting in diffi...

AI Technical Summary

Problems solved by technology

[0002] Existing plastic foam board materials include: ethylene-vinyl acetate copolymer, POE elastomer plastic, high-pressure low-density polyethylene, low-pressure high-density polyethylene, high-low-voltage composite polyethylene and other plastics, as well as antistatic agents, flame retardants, etc. Agents, chemical additives, calcium carbonate fillers, etc., the use of the above materials to produce plastic foam sheets with two high-performance antistatic and flame retardant effects is not ideal

There are four main defects: First, the material is difficult to decompose, because in order to achieve good antistatic and flame retardant effects, the amount of antistatic agent and flame retardant must be increased, resulting in difficult decomposition of the material during production and poor compatibility

The boards produced often have egg or peanut-sized bubbles, which are uneven and seriously affect product quality; second, the environmental protection effect of the materials is average, and cannot meet the highest standards in the industry; third, the original formula and production process are no longer suitable Development needs; Fourth, in practical applications, fire and explosion accidents occur from time to time due to the lack of anti-static function of plastic foam boards, or fire accidents also occur because the flame retardant effect of plastic foam boards does not meet the relevant standards

That is to say, for a long time, the plastic foam board has anti-static function but no flame-retardant function, or has flame-retardant function but no anti-static function, or even if it has two functions at the same time, the effect is not ideal and the function is unstable.

The anti-static and flame-retardant functions are not ideal, and because the production process is rough and outdated, and the details are not well grasped, the material is poorly decomposed, the foamed plastic sheet is foamed, the density is not enough, and it is not neat and beautiful; at the same time, in the development of environmentally friendly new materials The development and utilization and production technology are conservative and innovative, which also restricts a wider range of applications, especially in the fields of security and protection, which are difficult to meet the particularity and high requirements. Therefore, the fire and explosion accidents caused great harm to the country and people's life and property. damage
