Problems solved by technology

When producing all-steel anti-static floor and ceramic anti-static floor, the mold must be opened first to extrude the floor according to the size of the mold. When installing the floor, it is necessary to make a steel frame to fix the floor, and then install it on the ground to make the floor. The production and installation are complicated and costly. And heavy, inconvenient to install

Embodiment

[0020] Example: An Electromagnetic Shielding Composite Sheet

[0021] It is made by mixing raw materials in the following weight ratio: polyethylene resin 75kg; PE toughening agent 15kg; nickel-plated, silver-plated conductive graphite powder 20kg; nano-shielding electromagnetic wave conductive heat insulation powder 15kg; tribasic lead sulfate 3kg; PE wax 2.5kg ; PE modifier 2kg; Nali synthetic agent 20kg.

[0022] In the present invention, polyethylene, commercially available, referred to as PE, is a thermoplastic resin obtained by polymerization of ethylene. Odorless, non-toxic, feels like wax, has excellent low temperature resistance, good chemical stability, can withstand most acid and alkali erosion, insoluble in common solvents at room temperature, PE low temperature resistance, minimum operating temperature -70 ~ -100 ° C, Low water absorption, excellent electrical insulation properties. The present invention can use LDPE: ie low density polyethylene, high pressure p...

Abstract

The invention relates to an electromagnetic shielding synthetic board which is mixed by the following raw materials in parts by weight: 70-80 parts of polyvinyl resin, 10-20 parts of PE (poly ethylene) flexibilizer, 15-30 parts of metallic coating graphite powder, 10-20 parts of electromagnetic powder, 2-5 parts of stabilizing agent with an acid absorption effect, 2-3 parts of PE lubricating agent, 1-3 parts of PE modifying agent or elastomer, and 10-30 parts of PE synthesizing agent. The electromagnetic shielding synthetic board has the advantages of multiple purposes, such as electromagnetic interference and external signal shielding, effective dust prevention, static electricity prevention, and effective sound insulation, and is applicable to places where electromagnetic shielding is required.

Description

technical field [0001] The invention relates to an electromagnetic shielding synthetic board. Background technique [0002] Existing decorative boards have a single function. For example, the existing anti-electromagnetic shielding boards used in buildings are mostly made of metal plates or metal wires mixed with other materials to make floors, wall panels, and ceilings. The metal plate needs to consume a lot of expensive copper, and it is bulky and heavy, and the installation work is extremely troublesome; the metal wire mixture made of metal wire and other materials, because the metal wire is woven into a mesh, the shielding effect is the same as that of the metal wire The density of the woven mesh is directly related to the shielding effect. [0003] Existing sound-insulating materials used for buildings mostly use fiber materials as floors, wall panels, and ceilings for sound-insulation. Since fiber is used as a sound-insulating material, it is necessary to complete th...
