Abstract
The invention relates to a sound and heat insulating material and a manufacturing method thereof and relates to the sound and heat insulating material for making an automobile engine hood and the manufacturing method thereof. The invention is mainly invented to solve problems that the traditional sound and heat insulating material is easy to degrade, age and so on. Glass fiber and nylon short fiber 6 or nylon short fiber 66 are used as raw materials according to a weight percentage of 45-65%:55-35%. The manufacturing method comprises the following steps: respectively feeding two raw materials to a bale opener and opening the two raw materials in the bale opener according to the raw material weight ratio; roughly opening the raw materials; mixing the raw materials in a bin cotton feeding machine; finely opening the raw materials in a fine opener; feeding the raw materials to an airflow lapper through an airflow lapping cotton feeding machine; carrying out airflow lapping on the raw materials; and then needling the raw materials by using a needling machine; needling the upper surfaces and the lower surfaces of the raw materials; and finally, slitting the raw materials and packaging the raw materials in rolls. The sound and heat insulating material provided by the invention has the advantages of aging resistance and non-degradability.
Description
Technical field;
The present invention relates to a kind of sound and thermal insulating material and production method thereof that automotive hood is used of making.
Background technology:
The sound and thermal insulating material of existing making automotive hood adopts the hard polyurethane foam material to make more, and its weak point is the long-time easily degraded, aging of using, and affect the sound-insulating and heat-insulating effect, and elasticity is relatively poor, and elastic recovery is bad.
Summary of the invention:
Technical problem to be solved by this invention provides a kind of long-time use and is difficult for degraded, aging, and sound-insulating and heat-insulating is effective, the sound and thermal insulating material of good springiness and production method thereof.
Above-mentioned purpose is achieved in that described sound and thermal insulating material take glass fibre and nylon short fibre 6 or nylon short fibre 66 as raw material, and the percentage by weight of glass fibre and nylon short fibre 6 or nylon short fibre 66 is 45%-65%:55%-35%.
The specification of described glass fibre is: fibre diameter 7-11 μ m, length 55-70mm; The fibre number of described nylon short fibre 6 or nylon short fibre 66 is that 3.33-9.0dtex, length are 55-70mm.
Production method is: according to described raw material weight percentage, glass fibre and nylon short fibre 6 or nylon short fibre 66 are fed to respectively the bale opener shredding, thick shredding, mix to large storehouse cotton feeder, carry out smart shredding to refined opener again, behind the air lay cotton feeder, carry out air lay to random web-laying equipment, then carry out acupuncture with needing machine, upper and lower faces acupuncture is cut at last again, baling.
The pricker model of described needing machine is 15*18*32*3.5R222F32301, described upper and lower faces acupuncture, and a needling density is 10-30 pins/cm
2, depth of needling 8-15mm; The another side needling density is 8-20 pins/cm
2, depth of needling 5-10mm.
Product grammes per square metre 300-1200 gram/m
2, product thickness 3-15mm.
Advantage of the present invention is: ageing-resistant with the sound and thermal insulating material good springiness that this method is produced, do not degrade weak acid resistant weak base, long service life; The Nomex porosity that adopts air lay acupuncture to make is large, good product performance, the intensity of glass mat can improve about 2 times behind the adding nylon fiber, and heat resistance is good, can also satisfy the requirement of later process drawing and forming, can be made into difform sound-insulating and heat-insulating product.
