Dampproof silence pad and preparation process thereof

Abstract

The invention discloses a dampproof silence pad and a preparation process thereof. The preparation process comprises the following steps: mixing low density polyethylene and a hollow material and performing banburying to obtain semi-finished product particles A; mixing low density polyethylene, a foaming agent, an antioxidant and a coupling agent and performing banburying to obtain semi-finished product particles B; mixing low density polyethylene, a toughening agent and a lubricant and performing banburying to obtain semi-finished product particles C; mixing low density polyethylene and a coloring agent and performing banburying to obtain semi-finished product particles D; drying the semi-finished product particles A, B, C and D, stirring and mixing uniformly, and extruding into a sheet E by a single screw extruder; performing radiation crosslinking of the sheet E through a high-frequency high-voltage electron accelerator to obtain a foaming master slice F; preheating the master slice F by a horizontal foaming furnace, performing high-temperature foaming in a vertical foaming furnace, and sequentially performing the processes of calendering setting, corona, punching, trimming and coiling to obtain a coil of the dampproof silence pad; and performing thermal compounding between the coil G and PE films different in thickness on a compound machine with a heating device, and performing online slitting and coiling to obtain the dampproof silence pad.

Description

technical field [0001] The invention relates to a floor mat for laying floors, in particular to a moisture-proof and silent mat and a preparation process thereof. Background technique [0002] When paving various composite and solid wood floors, a layer of floor mat material should be laid on the ground first, so as to play the role of sound attenuation, heat preservation and moisture resistance. With the improvement of living standards, people pay more attention to the living environment and quality of life, especially environmental protection materials have become everyone's first choice. The current floor mat materials have strong smell, poor rebound, large cells, Defects such as poor hand feel and unstable product quality; the preparation process of the moisture-proof and sound-absorbing mat is complicated, and the produced moisture-proof and sound-insulating mat has poor processability. Contents of the invention [0003] In order to overcome the deficiencies of the p...
