[0045] The present invention also provides a method for preparing the slurry for thermal fabric described in the above technical solution, comprising the following steps:
[0046] a) mixing polyimide and a solvent to obtain a first mixture;
[0047] b) mixing the first mixture obtained in step a) with an adhesive, a crosslinking agent, and an accelerator, and then stirring to obtain a slurry for thermal fabrics.
[0048] In the present invention, the polyimide and the solvent are firstly mixed to obtain the first mixture. In the present invention, the polyimide and the solvent are the same as those in the above technical solution, and will not be repeated here.
[0049] In the present invention, there is no special limitation on the mixing method, and the technical scheme of simple stirring well known to those skilled in the art can be adopted, and the purpose is to mix the raw materials evenly.
[0050] After the first mixture is obtained, the present invention mixes the obta...
Embodiment 1
[0067] (1) Mix 5 parts by weight of polyimide powder and 30 parts by weight of DMF, and simply stir evenly to obtain the first mixture.
[0068] (2) The first mixture obtained in step (1) is mixed with 100 parts by weight of solvent-based polyurethane, 5 parts by weight of crosslinking agent, and 3 parts by weight of accelerator, and stirred for 5 minutes at a speed of 1000 r / min by an electric stirrer to obtain Polyimidecoating paste, that is, paste for thermal fabrics.

Abstract
The invention provides a sizing agent for thermal fabric and a preparation method and application of the sizing agent. The sizing agent for the thermal fabric is prepared from the following raw materials in parts by weight: 2-10 parts of polyimide; 25-35 parts of a solvent; 80-120 parts of an adhesive; 5-10 parts of a cross-linking agent; and 2-5 parts of an accelerant, wherein the cross-linking agent is blocked isocyanate. Compared with the prior art, the sizing agent for the thermal fabric provided by the invention utilizes the characteristic of low thermal conductivity of a polyimide material, adopts specific content components, realizes relatively good overall interaction, can endow the fabric with excellent thermal insulation performance, is good in stability, does not cause any influence on the structure and performance due to dyeing and finishing procedures, and is suitable for preparing the thermal fabric.
Description
technical field [0001] The invention relates to the technical field of functional fabrics, and more specifically relates to a slurry for thermal fabrics and a preparation method and application thereof. Background technique [0002] With the development of the economy and the progress of the society, people have gradually increased their functional requirements for clothing, and thermal fabrics have become a hot spot in the research and development of clothing. In recent years, the existing technology mainly improves the thermal performance of fabrics through functional chemicals. For example, the Chinese patent whose publication number is CN107447536A discloses a kind of warm-keeping fabric and its preparation process, and ceramicpowder is added in the spinning solution or coatingslurry to realize the far-infrared warming function of the fabric; The patent discloses a grapheneslurry, fabric and its preparation method and clothing, and the grapheneraw material is added ...
