Problems solved by technology

Among them, the air permeability refers to the amount of air passing through the material in a certain period of time under a certain pressure and measurement area. Measure the time required for air to pass through the diaphragm, high air permeability indicates long air permeability time, poor permeability

Abstract

The invention relates to an automobile engine room baffle material and a preparation method thereof. According to the automobile engine room baffle material, the mass per unit area is (80-200)g/m<2>, the air permeability is <=400L/m<2> S, the hydrostatic pressure resistance is >=1.6kPa, and the flame retardant property reaches B1 level which is regulated on automobile trim fabrics by GB/T17951-2006 inflaming retarding fabrics. Split superfine fibers are subjected to splitting and reinforced forming in a spunlaced nonwoven mode and then subjected to dyeing, flame retarding and water repellent finish to form the baffle material. The automobile engine room baffle material has good sound insulation, oil repellency and flame retardant property, and is applied to automobile engine room baffles and the like.

Description

technical field [0001] The invention relates to the field of textiles, in particular to an automobile engine cabin partition material and a preparation method thereof. Background technique [0002] Car noise is an important factor affecting car comfort and driving safety. The noise inside the car not only increases the fatigue of drivers and passengers, but also affects the driving safety of the car. Therefore, controlling the noise in the car to the lowest level has always been the goal pursued by car designers. [0003] Engine noise is one of the important sources of car noise. Therefore, the most important measurement index for the partition material of the engine compartment is the effect of blocking noise, and at the same time, the product is required to have anti-fouling, flame-retardant and other effects. [0004] Most of the sound-absorbing materials currently used are porous materials. Porous materials mainly absorb sound energy through the viscous friction of t...
