Description
Technical Field
The application relates to the field of heat preservation and insulation materials, in particular to the technical field of C04B38/08, and more particularly relates to a high-dispersion aerogel fiber master batch and a preparation method and application thereof.
Background
Aerogel is a material with 'infinite' nano-scale holes, and extremely high porosity leads to extremely low density and heat conductivity coefficient, so that the aerogel has great application potential in the field of heat insulation. At present, in the research and development of thermal fibers in the textile field, new paths are explored at home and abroad, namely aerogel and chemical fibers are combined to prepare fibers. The functional master batch is prepared by blending aerogel powder and plastic powder, and the aerogel is too light, so that the dispersion is poor, and various problems such as difficult discharging or uneven granules occur in the granulating process. In addition, along with the increase of people to environmental protection demand, the conventional aerogel powder that adopts directly mixes granulation with the material can cause dust pollution, has various potential risks. Therefore, exploring an aerogel to be mixed with materials uniformly is a current urgent problem to be solved.
Chinese patent application No. CN 112410922A "a preparation method of aerogel-containing polyester fibers", wherein aerogel microspheres are mixed with first polyester resin powder to obtain uniform mixed powder, then uniformly mixed with second polyester resin slices for extrusion granulation, then uniformly mixed with third polyester resin slices for melt spinning, and in some embodiments, dispersing agents and antioxidants are added, but the problem of incompatibility in the direct mixing process of aerogel and plastic powder cannot be solved in practice. Chinese patent application No. CN 111534007A "multifunctional composite antiviral and antibacterial fiber master batch and preparation and application thereof" discloses that aerogel is adopted as various antiviral and antibacterial carriers, and then the aerogel is mixed with various fiber matrixes and spun by various spinning methods to prepare the antiviral and antibacterial fiber with heat-insulating effect. By loading the material in the aerogel structure, the dispersion properties when mixed with the fibrous matrix can be improved, but the insulating properties of the aerogel can be affected by the pore structure as a carrier.
Chinese patent application publication No. CN 110305340A "an aerogel composite plastic master batch, a preparation method and application thereof", wherein an aqueous resin and aerogel are mixed to obtain a mixed solution, and then the mixed solution is dispersed into a plastic matrix for re-granulation after spray drying and granulation, the resin in the heat insulation master batch cannot be removed before granulation, so that the basic performance of the master batch matrix is changed, and the efficiency is reduced due to repeated granulation. Chinese patent application No. CN111533990A "Heat insulation master batch and preparation method thereof", heat first polymer and nano pore material in the cylinder of plunger extruder to partial plasticize, start the plunger, extrude and granulate to get premix, then mix with second polymer and extrude and granulate with twin screw, but according to the patent, "first polymer particle located in Zhou Rongrong state can be coated on the surface of nano pore material", must ensure that there is always first polymer in molten state in the cylinder.
Therefore, there is a need for a method that can effectively mix aerogels with fibrous substrates and that can achieve continuous, efficient production.

TABLE 1
Comparative example 1
This comparative example provides a highly dispersed aerogel fiber masterbatch, the embodiment being the same as example 1; the difference is that the addition amount of the ceramic powder is 0 part; the amount of the surfactant added was 0.65 part.
The density of the aerogel paste obtained was 0.33g/cm 3 The content of aerogel powder is 22.96wt%.

The aerogel master batch was heated to 280℃and cast into a 10cm 2mm sheet with a thermal conductivity of 0.085W/(m K).
Comparative example 2
This comparative example provides a highly dispersed aerogel fiber masterbatch, the embodiment being the same as example 1; except that the aerogel paste was replaced with aerogel powder within the scope of the present application.
The tap density of the aerogel powder is 0.2g/cm 3 。
The aerogel theoretical content of the obtained aerogel master batch is 50wt%, the bleaching powder is serious in the actual mixing process, the mixing weight ratio of the aerogel powder to the resin matrix is far lower than 1:1 through multiple tests, and the problems of difficult discharging, difficult smooth extrusion and the like still exist in granulating, so that the master batch is nonuniform.
The aerogel master batch was heated to 280℃and cast into a 10cm 2mm sheet with a thermal conductivity of 0.12W/(mK).
Comparative example 3
This comparative example provides a highly dispersed aerogel fiber masterbatch, the embodiment being the same as example 9; the difference is that the addition amount of the aerogel powder is 60 parts; the amount of the surfactant added was 1.35 parts.
The density of the aerogel paste obtained was 0.65g/cm 3 The content of aerogel powder is 22.11wt%.
The aerogel content of the obtained aerogel masterbatch was 14.74wt% (aerogel powder accounted for 44.22wt% of the resin matrix).
The aerogel master batch was heated to 280℃and cast into a 10cm 2mm plate with a thermal conductivity of 0.043W/(m K).
Comparative example 4
This comparative example provides a highly dispersed aerogel fiber masterbatch, the embodiment being the same as example 11; the difference is that the addition amount of the aerogel powder is 20 parts; the amount of the surfactant added was 5.15 parts.
The density of the aerogel paste obtained was 1.99g/cm 3 The content of aerogel powder is 1.93wt%.

The aerogel master batch was heated to 280℃and cast into a 10cm 2mm panel, the thermal conductivity of the test panel being 0.078W/(m K), higher than that of example 11.
Compared with example 9, the thermal conductivity of the plate of comparative example 3 is higher, because the density of the paste is too low due to the addition of too much aerogel powder, the adaptation effect with the resin matrix is poor, uneven dispersion occurs when the paste is mixed with the resin matrix, and the masterbatch is uneven in texture, thereby affecting the performance. In addition, although the thermal conductivity of comparative example 3 was lower than that of some examples, 60 parts of aerogel powder was added in comparative example 3, the content of aerogel powder in the paste was 22.11wt% which was far higher than that of the other examples, indicating that the effect of lowering the thermal conductivity could not be obtained by increasing the added amount of aerogel powder at one time, indicating that the added amount of aerogel powder defined in the present application was appropriate.
Compared with the embodiment 1, the comparative example 1 is free from adding titanium dioxide to prepare a paste with lower density, and when the paste is mixed with PET powder, the density difference is large, so that the mixing effect of aerogel powder and a plastic matrix is not ideal, layering phenomenon occurs, the blanking is difficult, the uniformity of the produced aerogel master batch is poor, the heat conductivity coefficient of the aerogel master batch is influenced, and the heat preservation performance of the aerogel master batch is poor. In comparative example 2, aerogel powder and PET powder are directly added for mixing, and the density difference between the aerogel powder and the density of the plastic matrix is very poor, so that the mixing effect of the aerogel powder and the plastic matrix is very poor, the aerogel powder floats on the upper part of the mixture, layering phenomenon occurs, the mixture is difficult to discharge during granulation, and the uniformity of the produced aerogel fiber master batch is very poor. The aerogel paste prepared in comparative example 3 and comparative example 4 respectively use more and less aerogel powder, the density of the prepared aerogel paste is lower and higher, the prepared aerogel paste is mixed with a resin matrix, the prepared aerogel paste is unevenly dispersed, and the prepared aerogel paste has uneven texture, so that the performance is affected.
According to the high-dispersion aerogel fiber master batch, based on excellent granulating formability of a plastic matrix, aerogel is added to enhance heat insulation performance of the high-dispersion aerogel fiber master batch, and a density-matched mixed system is designed, so that the prepared master batch not only has good strength and toughness, but also has high heat insulation performance. In comparative example 1, a low-density paste material was mixed with a resin matrix, and the density was greatly different, so that the mixing was not uniform during actual mixing, the discharging was difficult during granulation, and the master batch was not uniform. It is stated that the density of the paste and the plastic matrix must be adapted within a certain range in order to achieve good granulation. Comparative example 2 the aerogel powder within the limits of the present application was mixed with the resin matrix to be granulated, and the blanking was difficult, so that a high density paste was required to be prepared. Comparative example 3 the aerogel powder used to prepare the paste was added in an amount above the upper limit defined by the present application, and although the aerogel content in the obtained paste was up to 14.74% by weight, the thermal conductivity of the prepared sheet was 0.043W/(m.k), which was higher than that of comparative example 9 (0.03W/(m.k)), indicating that on the basis of the paste formulation defined by the present application, the aerogel powder addition was continued to be increased although the aerogel content in the paste could be increased and the corresponding effect of lowering the thermal conductivity could not be obtained, indicating that the aerogel powder addition defined in the present application was suitable. Comparative example 4 the aerogel powder used to prepare the paste was added in an amount falling outside the lower limit defined by the present application, the density of the prepared paste was increased, the aerogel content was decreased, the dispersibility of the aerogel in the resin matrix was decreased due to the increase in density, the performance was affected, and the decrease in the aerogel content also resulted in an increase in the thermal conductivity. In addition, compared with a resin matrix (such as PET master batch, the heat conductivity coefficient at room temperature is about 0.2W/(m.K)), the aerogel master batch disclosed by the application has better heat insulation performance than a pure resin master batch, and has high practical application value.
