Description
Technical field
The present invention relates to a kind of automotive interior material, specifically a kind of non-woven fabrics and the compound automobile interior decoration of woven fabric
Material.
Background technique
The structural material of automobile is mainly metal material, but interior material is mainly high molecular material.Wherein polyurethane
(PU) plate and compound (GMT) plate of glass fiber reinforced thermoplastic polymer are current automotive upholstery common used materials.But PU
Plate poor rigidity, anti-interference Qu Xingneng are weak；GMT plate is producing and is being easy to produce in fibre dust due to using glass fibre,
Directly pollute the respiratory system and skin of human body.Above-mentioned two classes material is difficult to degrade in nature, and obsolete material brings ring
Border pollution problem.
Summary of the invention
The purpose of the present invention is to provide a kind of non-woven fabrics and the compound automotive interior material of woven fabric, by the strong day of rigidity
Right flaxen fiber is produced after being sufficiently mixed with polypropylene fibre with unwoven manner, then passes through the two-sided composite polypropylene braiding of needling process
Cloth is molded as type part, low in cost, durable.
To achieve the above objectives, the technical solution adopted by the present invention are as follows:
Step 1, the staple fiber that natural fiber is cut to 50~70mm, are put into rustless steel container that be blended into sodium bicarbonate molten
Liquid stirs 60~80 minutes, and solution, which is blended into be subject to impregnate, to be flooded and can stir, and sodium bicarbonate solution is by 99% sodium bicarbonate of purity
It is mixed by 10~20% weight point with clear water and constitutes solution；
Step 2 cleans flaxen fiber with clear water, removes the soda solution in natural fiber, is then placed in 20~30 DEG C
Constant temperature bath 60~80 minutes in warm water remove remaining sodium bicarbonate in fine liquid, then vacuum drying treatment；
Step 3, by be added in the natural fiber after drying weight point 0.5~1.2% styrene monomer and 0.8~
0.12% ammonium ceric nitrate is dried after being cleaned after being chemically reacted with clear water；
Natural fiber after drying is placed on to be mixed to prepare on mao machine equipment with polypropylene fibre shredding and mixes fibre by step 4
The proportion parts by weights of dimension, natural fiber and polypropylene fibre matches are as follows: and natural fiber 50~70%, polypropylene fibre 30~
50%；
Step 5 reticulates the composite fibre carding machine combing after shredding；
Step 6, the multilayer for using parallel laid net mode to be paved into weight per square meter as 1500g the composite fibre after networking
Dictyosome；
Step 7 overlays surface layer of the polypropylene woven cloth as two sides on the above-mentioned multilayer dictyosome two sides being paved into, then pierces through needle
Machine reciprocating motion is reinforced；
Step 7 is suppressed into automotive interior material profile using molding apparatus by step 8.
In above-mentioned technical proposal: the natural fiber in step 1 is one of sisal fiber or ramee.
It is shredding twice that shredding, which mixes its shredding, in step 4.
Polypropylene woven cloth is 100~150g/m2 in step 7.
Molding apparatus pressure is 3~5MPa in step 8, and molding temperature is 170~220 DEG C, and clamp time is 5~30 points
Clock.Thus material can be allowed during heating, it can be effective by the flaxen fiber handled well and the polypropylene fibre of molten condition
Combination, surface layer polypropylene woven cloth also can closely and inner layer material combination.Product strength is than untreated after being molded
Product strength improves 3 times.
The present invention has following significant advantage effect compared with prior art products:
First is that raw material easily obtains, and cheap；
Second is that sisal hemp or ramee have good strength and permeability, it is mutual to become advantage after mixing with polypropylene
The chaotic condensating fiber of benefit；
Third is that it is rigidly especially good to use nonwoven production mode to spread the type part constituted for multilayer network structure, tension energy
Power is strong；
Fourth is that without, without any disposal of pollutants, having in any dust phenomenon, especially production process in production and use process
Sharp environmental protection；
Fifth is that process flow is short, it is easily universal to produce and facilitate operational administrative.
Six, since material is combined by non-woven material and Woven, material have dual mechanical property and
The firm feature of lightweight.Surface layer polypropylene cloth, which can completely cut off, simultaneously obtains vapor in air, material is made to have water-proof function.
