Embodiment Construction

[0019] Such as figure 1 Shown, the production technology of nano intelligent type odorless automobile interior material is characterized in that, comprises the following steps:

[0020] Step 1. Weigh the raw materials and set them aside. The raw materials are composed of the following components by weight percentage: 5% to 10% nano-SiO 2 Powder, 55% to 60% of reinforcing fibers and 30% to 40% of odorless polypropylene short fibers;

[0021] Wherein, the reinforcing fiber is one of short glass fiber, hemp fiber or regenerated fiber;

[0022] Step 2: Mix the reinforcing fiber with the odorless polypropylene short fiber according to the ratio described in the step 1 to obtain the mixed fiber, and the mixed fiber passes through the rough opener, the fine opener, the large warehouse mixing box, and the quantitative cotton feeder in sequence , carding machine, and web laying machine to form a uniform fiber web;

[0023] Step 3, the fiber web obtained in step 2 is consolidated and...

Abstract

The invention discloses a production process of an intelligent odorless automotive interior nanomaterial and belongs to the technical field of novel material processing. The process comprises materialpreparation, blending, coarse opening, fine opening, large-bin cotton blending, quantitative cotton feeding, carding, netting, pre-needling, primary needing, trimming and winding, unwinding of bottom-layer needled felt, roll type powder scattering, electronic alignment and unwinding of upper-layer needled felt and 2-3 times of needling and composition to obtain composite needled felt, winding, unwinding of the composite needled felt, far infrared preheating, blowing through heating, multi-roll cold rolling, cutting, obtaining of a finished product, inspection and packaging. By means of the process, nano SiO2 powder is composited between two layers of needled felt, the intelligent odorless automotive interior nanomaterial is obtained, the aldehyde release amount reaches the environmental protection standard, the environmental protection grade reaches the grade E0, the flavor is smaller than the grade 1, the sterilization and disinfection capability reaches 95% or above, the sound absorption coefficient is improved by 30%-40%, noise is reduced by 10-15 db and the weight is reduced by 10%-20%.

Description

technical field [0001] The invention belongs to the technical field of new material processing, and in particular relates to a production process of a nano-intelligent odorless automotive interior material. Background technique [0002] Now my country has become the world's largest automobile production and sales country, and the production and sales of automobiles in 2017 are close to 30 million. The automobile industry has become the pillar industry of my country's national economic development, and its development prospects are in the ascendant. [0003] In recent years, with the popularization of family cars, the air quality inside the car has attracted more and more attention. Especially for new cars, the harmful gas pollution in the car is often serious. It is an indisputable fact that the toxic and harmful gases in many new cars seriously exceed the standard. Most of the new cars in our country have the problem of excessive formaldehyde or benzene content in the air ...
