LLDPE modified isotatic polypropylene non-woven fabric and preparation method thereof

Abstract

LLDPE modified isotatic polypropylene non-woven fabric consists of a top layer, a back layer, and a fiber cotton layer disposed between the top layer and the back layer. The top layer and the back layer are made from a non-woven fabric material, and the non-woven fabric material is prepared from the following raw materials in parts by weight by employing a melt blowing method: 100 parts of isotactic polypropylene, 2-3 parts of nanometer-level kaolin, 7-9 parts of montmorillonite, 1-2 parts of sodium hyposulfite, 2-3 parts of alumina silicate, 1-2 parts of citric acid, 1-2 parts of calcium phosphate, 12-15 parts of linear low-density polyethylene (LLDPE), 1-2 parts of an aluminate coupling agent DL-411, 12-15 parts of dioctyl terephthalate, 7-9 parts of silkworm excrement, 1-2 parts of cortex mori, 2-3 parts of ligusticum wallichii, 1-2 parts of angelica dahurica, 2-3 parts of houttuynia cordata and 4-5 parts of an auxiliary agent. The non-woven fabric provided by the invention has the characteristics of being resistant to heat, resistant to corrosion, resistant to tearing and high in strength, has aromatic smell and sterilization effect, and is capable of adsorbing harmful gases and peculiar smells by utilizing silkworm excrement for carbonization processing.

Description

technical field [0001] The invention relates to the technical field of nonwoven fabrics, in particular to an LLDPE modified isotactic polypropylene nonwoven fabric and a preparation method thereof. Background technique [0002] Non-woven fabric, also known as non-woven fabric, has the characteristics of moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, low price, and recyclable. It is widely used in wallpaper, handbags, medical and health, architectural decoration, clothing, Automotive interior decoration and other fields. [0003] The current non-woven fabrics still have some unsatisfactory shortcomings: such as the release of harmful organic substances, endangering human health; insufficient bonding, easy to disperse, poor tensile strength; limited flame retardant effect, etc. Researching non-woven fabrics with different properties for different purposes is the trend of further development of non-woven fabrics.
