Abstract
The invention discloses a flame-retardant sepiolite-based hybrid sol coated polyester-cotton fabric and a preparation method thereof. The sepiolite-based hybrid sol is coated on the surface of the polyester-cotton fabric, and is pre-baked and then baked to obtain the flame-retardant sepiolite-based hybrid sol coated polyester-cotton fabric, and the step can endow the polyester-cotton fabric with water washing resistance and flame retardance. The sepiolite-based hybrid sol prepared by the method overcomes the defects of small molecular weight and large brittleness of the traditional silica sol prepared by taking silicate as a raw material, has a certain molecular network structure, can form a film with certain flexibility on the surface of a textile, and endows the textile material with flame retardance and certain mechanical property.
Description
Technical Field
The invention belongs to the technical field of hybrid sol-coated polyester-cotton fabric and preparation thereof, and particularly relates to a preparation method of a flame-retardant sepiolite-based organic/inorganic hybrid sol-coated polyester-cotton fabric.
Background
With the progress of society, the performance of various materials is gradually developed, however, the flame retardance of flexible materials is still an important proposition. The blended fabric represented by polyester cotton has wide application range due to various excellent performances, but the performance difference among components is large, the combustion condition is complex, and the flame retardation problem of the material is not completely solved. Based on this, how to reduce the loss of lives and properties of people caused by burning textiles has been the focus of various social circles.
The flame retardant of textile materials began in the 19 th century and developed from temporary flame retardant to semi-durable flame retardant, durable flame retardant according to the flame retardant aging. Flame-retardant finishing methods of textiles are also various, and the common methods are mainly padding and baking methods. The traditional flame-retardant after-finishing of textiles has the defects of exceeding formaldehyde release, non-durable flame-retardant effect, rough hand feeling, reduced mechanical property and the like, and the wide application of flame-retardant textiles in the field of materials is limited.
The traditional preparation of the silica sol mainly uses tetraethyl orthosilicate and absolute ethyl alcohol to react under an acidic condition, so that the silica sol is generated, a flexible coating cannot be formed on the surface of a fabric after the generated sol is dried, the mechanical strength is poor, the silica sol is not suitable for preparing film materials, and flame retardant protection cannot be generated on the textile. The modification of the traditional silica sol mainly adopts small molecules or chain chemical reagents such as methyltriethoxysilane, silane coupling agents with different structures, polyethylene glycol and the like, the main aim is to improve the flexibility, mechanical properties and the like of the silica sol, the flame retardance and other functionalities of the silica sol are not obviously affected, and the combination of the silica sol prepared by the traditional method and textiles needs to adopt functional groups to functionally modify the silica sol, so that the silica sol is endowed with certain chemical activity, complex process and more limiting conditions.
Therefore, a preparation method of a flame-retardant polyester-cotton fabric product which is simple in process, good in flame retardance, environment-friendly and durable is needed.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide a flame-retardant sepiolite-based hybrid sol-coated polyester-cotton fabric and a preparation method thereof.
In a first aspect, the invention provides a preparation method of a flame-retardant sepiolite-based hybrid sol-coated polyester-cotton fabric, which comprises the following specific steps:
s1: dispersing sepiolite in water, and stirring to obtain sepiolite dispersion liquid;
s2: mixing the sepiolite dispersion liquid and a bio-based acidic substance and then reacting to prepare sepiolite-based hybrid sol;
s3: and coating the sepiolite-based hybrid sol on the surface of the polyester cotton fabric, and baking after pre-baking to obtain the flame-retardant sepiolite-based hybrid sol coated polyester cotton fabric.
Preferably, the sepiolite is α -sepiolite.
Preferably, the sepiolite dispersion in S1 is obtained by stirring the mixture with a homogenizer at a concentration of 1 to 10g/L.
Preferably, the bio-based acidic substance in S2 is phytic acid or polyaspartic acid.
Preferably, the concentration of the phytic acid solution is 5-15 g/L, and the concentration of the polyaspartic acid solution is 3-10 g/L.
Preferably, the weight ratio of the sepiolite dispersion to the bio-based acidic substance is 0.2 to 1.
Preferably, the sepiolite-based hybrid sol prepared in the step S2 is prepared at a temperature of 25-95 ℃ for 2-24 hours.
Preferably, the weight gain rate of the coating in S3 is 10% to 100%.
Preferably, the pre-baking temperature in the step S3 is 80-100 ℃ and the pre-baking time is 5-10 min; and S3, baking at 130-180 ℃ for 2-10 min.
In a second aspect, the present application provides a flame retardant sepiolite-based hybrid sol coated polyester cotton fabric prepared using the method of the first aspect.
Compared with the prior art, the invention has the following beneficial effects:
(1) The sepiolite is used as a raw material, mg atoms in a magnesium oxide octahedron in a sepiolite three-dimensional framework structure are dissolved out under an acidic condition, the three-dimensional framework structure is converted into an amorphous silica sol material, active groups in an organic acid structure react with Si-OH in the silica sol structure in the conversion process, the sol is modified, the sepiolite-based hybrid sol with certain mechanical properties is prepared, and the sol is applied to the field of flame retardance of polyester cotton fabrics for the first time;
(2) According to the invention, sepiolite is used as a raw material, functional groups in the prepared sepiolite-based hybrid silica sol structure are more, for example, si-OH in the silica sol can generate hydrogen bond action with C-OH on the surface of cotton fiber in polyester cotton fabric, phosphonate in the phytic acid structure can generate hydrogen bond or covalent bond with C-OH on the surface of cotton fiber, and-NH-, -C=O in the polyaspartic acid structure can generate hydrogen bond action with C-OH on the surface of cotton fiber, so that the coating fastness of the silica sol to the textile is improved, the process is simple, the energy consumption is lower, and the method can be used for industrial production;
(3) The sepiolite-based hybrid sol prepared by taking sepiolite as a raw material and phytic acid and polyaspartic acid as acid auxiliary agents is coated on the surface of polyester-cotton fabric in a coating mode, the main component of the sol is silica sol, other auxiliary agents are biological-based environment-friendly materials, and the problem of formaldehyde release is avoided; the sepiolite-based hybrid sol has certain flexibility, and the coated textile has soft hand feeling and does not influence usability; as different functional groups interact with the groups on the surface of the cotton fiber, and the material still has flame retardance after being washed by flame retardance test verification, the surface of the flame-retardant sepiolite-based hybrid sol-coated polyester-cotton fabric has washability.
