Embodiment 1

[0039] The preparation method of composite material nonwoven fabric is as follows:

[0040] 15kg of diatomite, 20kg of polypropylene, and 0.5kg of lubricant are used as raw materials. First, the polypropylene is heated and melted to form a melt, and then diatomite and lubricant are added to the melt. After mixing, the melt is sprayed out from the spinneret Fine flow, then condensed into fibers, the fibers are made into fiber suspension slurry, the suspension slurry is transported to the web forming mechanism, the fibers are formed into a web in a wet state and then reinforced into cloth to obtain the final product composite material non-woven fabric, the hardness of the prepared product is 460HV.

Embodiment 2

[0042] The preparation method of composite material nonwoven fabric is as follows:

[0043] (A) Weigh 48 kg of diatomite, wherein the mass percentage of diatomite with a particle size below 5 μm in the total mass is 60%, and the particle size of the remaining diatomite is all at 6-13 μm. SiO in diatomite 2 The mass percentage content is 86%, then diatomite is roasted at 400 ℃, then acidic treatment is carried out with the sulfuric acid that is 65% with mass concentration;

[0044] (B) take by weighing polyvinyl formal 85kg, fluorescent whitening agent and reductive agent total 3kg, (A) step processed diatomite, fluorescent whitening agent and reductive agent are added to polyvinyl formal to form In the spinning solution, after mixing, a fine stream is sprayed out through the spinneret, and solidified in the liquid coagulation medium to form fibers;

[0045] (C) The fibers are opened, carded, and laid into a fiber web, and then the fiber web is reinforced into a cloth by needl...

Embodiment 3

[0047] The preparation method of composite material nonwoven fabric is as follows:

[0048] (A) Weigh 35kg of diatomite, wherein the mass percentage of diatomite with a particle size below 5 μm is 70% of the total mass, and the particle size of the remaining diatomite is all at 6-13 μm. SiO in diatomite 2 The mass percentage content is 86%, then diatomite is roasted at 600 ℃, then acidic treatment is carried out with the sulfuric acid that mass concentration is 60%;

[0049] (B) Take polyethylene terephthalate and polypropylene total 70kg, wetting agent 2kg, wetting agent is added in the spinning solution that polyethylene terephthalate and polypropylene form, after mixing The spinneret ejects a thin stream, which is solidified in the liquid coagulation medium to form fibers;

[0050] (C) The fibers are opened, carded, and laid into a fiber web, and then the fiber web is reinforced into a cloth by needle punching, and the diatomite treated in step (A) is sandwiched between tw...

Abstract

The invention relates to the field of non-woven fabric, in particular to a composite non-woven fabric and a production method thereof. The composite non-woven fabric comprises, by weight, 15-48 parts of diatomite, 20-85 parts of fiber superpolymers and 0.5-3 parts of textile assistant. According to the composite non-woven fabric, inorganic powder of the diatomite is added into textile-fiber non-woven fabric to produce the non-woven fabric with a diatomite function, namely diatomite cloth, so that a part of textile fibers are replaced to reduce cost, and the objectives of saving oil resources and energy and reducing carbon dioxide emission are achieved; hydroxide radicals of the fibers are increased, so that the problems that a non-woven fabric body is hydrophobic and airtight and does not have a heat insulation function are solved.

Description

technical field [0001] The invention relates to the field of non-woven fabric manufacturing, in particular to a composite material non-woven fabric and a preparation method thereof. Background technique [0002] Diatomaceous earth has the advantages of extensibility, strong impact strength, tear strength, light weight, soft body, good wear resistance, and superior compressive strength. At the same time, it can improve the heat resistance, wear resistance, heat preservation, and Anti-aging and other chemical effects. Diatomaceous earth is the best raw material for non-metal heat insulation, sound insulation and heat preservation, and its refractoriness can reach 1380 degrees Celsius. It can play the role of thermal insulation and sound insulation, smooth and soft, with high compressive strength. It has strong plasticity and cohesiveness, and diatomite also has adsorption, dispersion, suspension and fluidity. Diatomite has a unique structure. There are many holes on the dia...
