The chelate type high molecular copolymer wetting dispersant selected by the invention is a high molecular weight block copolymer with inorganic powder affinity groups, and has high-efficiency wetting dispersibility. The hydrophobic aerogel powder has the advantages of effectively reducing the surface tension and interfacial tension of materials, reducing the contact angle of the hydrophobic aerogel powder, enabling the hydrophobic aerogel powder to be wetted by water, high-efficiency dispersibility, viscosity reduction and sedimentation resistance, enabling the hydrophobic aerogel to be wetted, dispersed and unfolded in water, and forming stable aerogel/water dispersion under the cooperation of polyethylene glycol mono-octyl ether.
The hydrophobic silica aerogel powder selected by the invention is a porous material with a porous internal network structure filled with gas and a solid appearance with low density. The porous ceramic material has high porosity, long heat conduction path and excellent heat insulation property. The pores with the aperture of 20-70nm can prevent air from flowing freely, thereby playing the roles of heat insulation and warmth retention. The hydrophobic surface of the aerogel has waterproof and antifouling properties, various substances are reduced from being stuck on the surface of the aerogel, and the hydrophobic property of the aerogel can keep the structure and the heat insulation effect of the aerogel in a humid environment. Its hydrophobicity may also increase the resistance to washing.
The silica aerogel dispersion liquid prepared by the invention has the advantages that the dosage of the surfactant and the wetting dispersant is extremely small, the dispersion liquid accounts for less than 2 percent, more than 98 percent of the dispersion liquid is the mixture of water and aerogel, and after the water volatilizes, the aerogel can completely recover the original characteristics, such as high porosity, hydrophobicity, high heat insulation property and the like. The prepared dispersion is placed for at least 1 hour, so that the occupation of water in the aerogel pores is fully ensured, polyurethane is prevented from entering the aerogel pores when being mixed with the polyurethane, and the polyurethane is reserved in the aerogel pores after film formation, so that the pores are blocked.
The invention controls the foaming ratio of the foam coating glue to be 1:2.2-2.5 or the weight foaming ratio to be 1:0.4-0.45. When the silica aerogel foam coating is added to a foam generator for foaming, a large amount of air is introduced into the system, so that the volume is increased, the weight is reduced, and a foam body is formed. The more the air is introduced, the larger the volume foaming ratio is, the larger the air volume in the polyurethane foam coating is, which is favorable for heat preservation and insulation, but the too much air volume can influence the polyurethane film forming fastness and the bonding fastness with the base cloth, conversely, the smaller the air is, the smaller the volume foaming ratio is, the smaller the air volume in the polyurethane foam coating is, which is favorable for the polyurethane film forming fastness, but the too little air volume is, and the heat preservation and insulation effect is not ideal. The foaming ratio controlled by the invention balances the contradiction between the two, and achieves the purposes of warmth retention, heat insulation, wear resistance, scratch resistance and washing resistance and excellent fastness. On the other hand, the proper control of the foaming ratio is also related to ventilation and windproof performance, the proper foaming ratio can enable micropores in the foam body to be staggered and overlapped, the channels are zigzag and roundabout, the air can be decelerated and turned when passing through, the windproof purpose is achieved, the humidity is driven by the concentration gradient, the zigzag channels can not influence the volatilization of the humidity, and the effect of high moisture permeability is achieved. The volume foaming ratio is too large, the ventilation quantity is larger, but the wind resistance is poor, the winter cold prevention and heat preservation are not facilitated, the volume foaming ratio is too small, the ventilation quantity is small, the wind resistance is good, but the ventilation quantity is too small, and the wearing is stuffy. The foaming ratio control of the invention can lead the ventilation amount to be 3mm/s-10mm/s, and achieve the excellent windproof ventilation effect with the windproof performance of 3 levels.
The invention controls the dry weight of the coating to be 20-50g/m 2. The larger the coating weight is, the better the thermal insulation effect is, but the heavy feel is brought to the fabric, and the smaller the coating weight is, the poor thermal insulation effect is. The dry weight is increased by the control of the invention, and the effects of soft and fluffy hand feeling, hydrophobic and breathable coating surface, warm keeping and heat insulation of the fabric, washing resistance and cold resistance of the light coating are achieved.
In summary, the preparation of the silica aerogel dispersion liquid, the selection of the silica aerogel foam coating adhesive, the water-proof finishing, the calendaring and the coating process treatment are carried out once, the foaming ratio of the foam coating adhesive is controlled to be 1:2.2-2.5 or the foaming ratio of the foam coating adhesive is controlled to be 1:0.4-0.45, so that the selected foam coating adhesive is firmly combined with the fabric under the conditions of 80-90-110-110 ℃, under the action of a blocked isocyanate crosslinking agent and a cerium isooctanoate drier, the silica aerogel, an organosilicon anti-adhesive agent and an 18-thirty-pentalone slip agent are effectively bonded on a polyurethane chain segment to form an overlapped and closely-connected polyurethane foam structure, and under the high temperature condition of 150-160-165-165 ℃, aliphatic polyurethane is further reacted and crosslinked, and simultaneously reacts and is crosslinked with an amido and an ester group on the fabric to form a polyurethane foam net structure, and all raw materials are synergistic, so that the film is fluffy and tough, the coating film with excellent combination is firm, the fabric has the effects of heat preservation, wind resistance, good fastness, soft scratch resistance, low-scratch resistance and wear resistance, and low hand feeling.

After the tatting fabric is treated by the provided glue solution, the obtained fabric keeps lower weight increase, is obviously superior to untreated fabric with the same gram weight in the aspects of wind resistance, ventilation, heat preservation and temperature locking, achieves the effects of wind resistance, ventilation, heat preservation and heat preservation by lower weight increase, has good fastness, is wash-resistant and durable, is scratch-resistant and wear-resistant, keeps soft in hand feeling at low temperature, and has good application prospects in the aspects of winter outdoor down jackets, cotton jackets and other cold-proof jackets.
