Abstract
A kind of polymer composite, raw material composition and weight part ratio include：Foaming concentrate 5~8, flame-retardant master batch 10~15, ldpe resin LDPE 50~80, ethylene propylene diene rubber EPDM 10~20, damping fluid 10~15, frictional heat agent 13~18, cross-linking radiation auxiliary agent 6~10, when preparation, mixing machine room temperature first is added in required ratio in all raw materials to mediate, it then drains into extrusion molding in single screw extrusion machine and obtains preformed sheet, cross-linking radiation is carried out to preformed sheet again, cross-linked thermoset polymer sheet material is obtained, is finally foamed to cross-linked thermoset polymer sheet material.The design can not only realize the continuous noise reduction in sustained sound environment, and have good heat preservation and flame retardant property.
Description
Technical field
The invention belongs to polymeric material fields, and in particular to a kind of polymer composite and preparation method thereof, mainly
At high residential building, public place of entertainment, mute place and sound-insulating.
Background technology
Ubiquitous city noise surrounds us, harasses our life.Or so midnight often hears various works
Crash when journey vehicle passes through from cell section, it is particularly ear-piercing, or citizen are waken up or noisy that mood is irritated, is difficult to fall asleep.
Moreover, noise pollution has become the environmental factor of influence health after air pollution, is likely to become the second health and " kills
Hand ".Before this, a report that the World Health Organization announces is for the first time to noise pollution " determining a crime "：Over-exposure in noise pollution,
Mental health can be not only seriously affected, the risk for the diseases such as suffer from a heart complaint can be also increased.Expert claims, such as a long time by noise jamming,
Will neurasthenia, there are dizziness, the symptoms such as visual fatigue.It is built in the high high level of intensive residential quarter, especially residential density
It builds, the noise for generation of normally living, seriously affects neighbourhood's life, produce serious neighbourhood's dispute.If not
It controls to make an uproar and mentions the important schedule of relevant departments, it will influence " Health China " implementation, harm is that the common people are especially old
The physical and mental health of people.In fact, the elderly is also noise deafness group of people at high risk.
Currently, sound insulation and noise reduction material mainly uses expanded material, such interiors of products has continuous fine and closely woven micropore, countless
Micropore and continuous pore, penetrate into surface each other between hole, principle of noise reduction is：When noise is incident on material surface
When, it penetrates into material internal continuation and propagates forward, in communication process, sound wave causes air movement in aperture, and abuts aperture
Air between gap is not easy to move, and the interior friction that this viscosity of air generates can convert acoustic energy to thermal energy, to make
Sound energy attenuation.This noise reduction mode there are problems that realize continuous noise reduction, therefore, noise reduction in lasting noise circumstance
Effect is limited.
Invention content
The purpose of the present invention is overcome the problems, such as existing for current material can not continuous noise reduction, a kind of sustainable noise reduction is provided
Polymer composite and preparation method thereof.
In order to achieve the above object, the present invention provides following technical schemes：
A kind of polymer composite, raw material composition and weight part ratio include：Foaming concentrate 5~8, low density polyethylene (LDPE) tree
Fat LDPE 50~80, ethylene propylene diene rubber EPDM 10~20, damping fluid 10~15, frictional heat agent 13~18, irradiation are handed over
Join auxiliary agent 6~10；
The composite material passes sequentially through cross-linking radiation by above-mentioned raw materials, foaming is prepared.
The raw material of the frictional heat agent forms and weight part ratio is：Ceramic powder 8~10, nanometer glass fiber 5~8.
The raw material of the foaming concentrate forms and weight part ratio is：Ldpe resin LDPE 50~80, foaming agent
20~30, blowing promotor 5~9.
The raw material composition of the composite material further includes flame-retardant master batch, and the weight part ratio with foaming concentrate is 10~15:5
~8；
The raw material of the flame-retardant master batch forms and weight part ratio is：Ethylene-vinyl acetate copolymer resin 50~80, methyl
Vinylsiloxane rubber 20~30, fire retardant 10~20, auxiliary agent 5~9.
The damping fluid is methyl-silicone oil, and the cross-linking radiation auxiliary agent includes crosslinking sensitizer trimethylol propane trimethyl
