The present invention has the following advantages: the composite inner decoration material of preparation has the performances such as lightweight, high strength, fire-retardant, sound insulation, sound-absorbing.And nontoxic, odorless, do not discharge toxic gas and volume of smoke, the compatibility of each fiber is good, improves the functional of vehicle inside decoration material, improves the quality as the automobile-used consumer goods greatly.
Detailed description of the invention:
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only for explaining the present invention, does not form limiting the scope of the present invention.
Invention shows the embodiment of a kind of composite interior material for motor car and preparation method thereof; Prepare composite and select content 60% aramid fiber 1314,20% polyester fire resistant fibre and 20% polyester hot melting fiber, preparation method's operating procedure is as follows:
1), aramid fiber 1314, polyester fire resistant fibre and polyester hot melting fiber open bag through bale opener, then through the pre-shredding of thick opener, then pass through the shredding of refined opener essence again through cotton blender machine mixing, then carry out combing with carding machine;
2), adopt nonwoven needled process technology that fiber lapping machine good for combing is carried out cross lapping, then carry out acupuncture processing with needing machine, then process with gassing frame and calender;
3), through acupuncture, singe, the semi-finished product after calendering are fibrofelt, more finally form composite inner decoration material with thermoplastic resin after fibrofelt is carried out compound hot pressing.
Fanglun l414 is novel high strength fibre, and its intensity can reach 193.6cN/tex, and elongation at break is 4%.Initial modulus, far above other fibers, is 11 times of polyamide fiber, is about 6 times of terylene, and there is high mechanical performance, there is high strength, high elastic modulus, can be high temperature resistant, at high temperature good stability of the dimension, percent thermal shrinkage is very low, and density is low, is conducive to the lightweight of goods, and high temperature resistant, there is corrosion resistance, chemical-resistant and anti-flammable.
Polyester fire resistant fibre and polyester hot melting fiber moisture pick-up properties very poor, the moisture regain under general atmosphere condition is 0.4%-0.5%, and therefore it is dry, fibre property change under wet condition is little.And intensity is high, elastic recovery is good.When percentage elongation is 3%, its elastic recovery rate is 90%-95%.Modulus is also high, and rigidity is large, and the anti-wear performance of goods is good.Self-characteristic can meet the performance requirement of the non-woven interior material high resilience of high-speed train chair, ABRASION RESISTANCE, and polyester doughnut also contributes to the heat-proof quality improving goods, meet security performance requirement, must carry out flame treatment to material.
The present invention has the following advantages: the composite inner decoration material of preparation has the performances such as lightweight, high strength, fire-retardant, sound insulation, sound-absorbing.And nontoxic, odorless, do not discharge toxic gas and volume of smoke, the compatibility of fiber is good, improves the functional of vehicle inside decoration material, improves the quality as the automobile-used consumer goods greatly.
The composite physical and mechanical properties prepared, fire-retardant, burning smoke density, indices such as cigarette poison grading etc. reach same kind of products at abroad level completely.Physical Mechanical embodies by weight loss ratio and ultimate strength, fire-retardantly embodied by fire-retardant index and flame retardant rating, the smoke density that burns, cigarette poison is embodied by smoke toxicity.
This product can reach following standard:
