[Industrial Field of Application] The present invention relates to the composition of a sizing agent used in manufacturing glass fibers, and an object of the present invention is to provide a sizing agent that exhibits an antistatic effect and exhibits less migration. [Prior Art] A sizing agent used in producing glass fibers usually contains a film forming agent and a lubricant as main components, and a silane coupling agent is added as necessary. In addition, the frizz caused by static electricity that is often observed during glass fiber manufacturing, and the chopped strands that adhere to the cutter during cutting become lumps and fall onto the belt conveyor, resulting in chopped strands of uniform thickness. An antistatic agent is added to the sizing agent in order to prevent problems caused by static electricity generation, such as failure to obtain strand mats.
Currently, ammonium chloride, lithium chloride, lithium nitrate, potassium chloride, sodium acetate, etc. are widely used as antistatic agents, but even if these antistatic agents are added, migration cannot be prevented and the thickness of the cake may be reduced. There was a drawback that the amount of antistatic agent deposited and the coloration after drying of the cake were uneven depending on the inside and outside sides of the cake, and the antistatic effect inevitably varied depending on the inside and outside of the cake. Furthermore, the migration part has the disadvantage of deteriorating the performance of the molded article, particularly the boiling resistance and transparency. [Problem to be solved by the invention] When a glass fiber bundle wound to a considerable thickness, such as a current cake or direct-wound roving, is dried, moisture evaporates from the surface of the cake, and as a result, moisture inside the cake evaporates. The glass fiber bundle gradually moves to the surface, and the solid components in the sizing agent also move together with the moving water, so that the closer the glass fiber bundle is to the surface, the higher the solid content becomes. This phenomenon is called migration, and when migration occurs, the following drawbacks occur. That is, the adhesion of the sizing agent to the glass fiber bundle becomes uneven between the inner and outer layers of the cake, etc., causing uneven quality. The amount of sizing agent deposited is particularly large on the exposed surface of the cake, etc., and sometimes coloring occurs after heating and drying. Therefore, the migration part is currently 200 to 400 g.
Approximately 100g of the inner layer and 300g of the outer layer were removed to produce roving or chopped strands.
This results in a large loss in product yield.
On the other hand, if the migration area is reduced, it will be very advantageous in terms of cost, and since there will be no areas where the antistatic agent in the intermediate layer is insufficient, it will be possible to suppress the generation of static electricity locally. From this point of view, Special Publication No. 42870 was proposed. It is true that when the sizing agent of this publication is used, migration is greatly improved and the above-mentioned drawbacks are eliminated. However, the strands obtained using this sizing agent are soft, and therefore, when cut with a cutter, the chopped strands get entangled with each other, resulting in poor dispersibility, and as a result, the glass fibers in the chopped strands become tangled. Dispersion was non-uniform, resulting in uneven strength of the glass fiber-reinforced molded product.Furthermore, the strands were soft, reducing workability during cutting.Additionally, the dried cake was slightly colored. . Further, there was a problem in that even though the material had a fairly high boiling resistance, it was desired to further improve the boiling resistance depending on the application. [Means for Solving the Problems] The present inventors have conducted various studies in order to obtain a sizing agent with less migration and a uniform antistatic effect, and as a result, a sizing agent containing octyldimethylammonium ethosulfate has been developed. This method was found to give extremely good results and was proposed as the present invention. In other words, the cake spun using the sizing agent of the present invention has less migration than conventional products, so the roving obtained from the cake has less fluff, and the generation of static electricity during the production of chopped strands is significantly reduced. As a result, uniformly dispersed chopped strands with no uneven product quality can be obtained, and as a result, the distribution of glass fibers in the reinforced plastic (FRP) is also uniform, improving transparency, and improving the appearance of the molded product. improves. Furthermore, the boiling resistance of FRP has also been improved. Thus, according to the present invention, octyldimethylammonium ethosulfate is included as an antistatic agent, and in addition, if necessary, a film forming agent,
Sizing formulations are provided that may include lubricants, silane coupling agents, and the like. The amount of octyldimethylammonium ethosulfate added to the sizing agent is preferably 0.1 to 1.0% by weight. If the amount of octyldimethylammonium ethosulfate added is less than 0.1% by weight, the antistatic effect will be extremely small, and the antistatic effect will be the same as that of currently used ammonium chloride, potassium chloride, etc. Further, even if 1.0% by weight or more is added, the increase in effectiveness is small compared to the increase in cost, and it can be said to be inefficient. The components other than the antistatic agent in the sizing agent of the present invention can be appropriately selected from those known in the art, and the amount added can be appropriately selected from well-known amounts. The method used for manufacturing can be applied as is. The rovings and chopped strands obtained using the sizing agent of the present invention are extremely useful and effective as reinforcing materials for not only unsaturated polyester resins but also epoxy resins and phenolic resins. [Example] Examples of the present invention are shown below, but the present invention is not limited thereto. Example 1 A sizing agent with the following composition was applied to glass fibers with a fiber diameter of 13 μm pulled out from a bushing so that the adhesion rate to the glass fibers was approximately 1.0% by weight, 800 fibers were bundled into a strand, and wound for 30 minutes. I took it and made it into a cake. Vinegar emulsion (solid content 50%) 10.0% by weight Octyldimethylammonium ethosulfate (solid content 50%) 0.6% by weight γ-methacryloxypropyltrimethoxysilane 0.3% by weight Stearic acid/tetraethylenepentamine condensate (solid content 30%) %) 0.1% by weight Glacial acetic acid 0.1% by weight Water Remaining amount When this cake was heated, almost no coloring occurred as a whole, and a uniform and sufficient antistatic effect was exhibited. On the other hand, when conventionally used ammonium chloride or lithium chloride is used instead of octyldimethylammonium ethosulfate, the former results in coloring of the migration area and uneven adhesion, and has a small antistatic effect and dries out. When cutting a cake, for example, if you try to cut the chopped strands with a fiber length of 1 inch, you will not be able to cut the fibers to the desired length, and the chopped strands will spread into the cutter. The disadvantage is that it scatters and adheres, and a certain amount falls as a lump, making it difficult to form a sheet of a certain thickness.Although the latter does not have the above disadvantages,
When made into an FRP molded product, the transparency and boiling resistance are significantly deteriorated, and the high cost increases the cost of glass fiber products. Example 2 The same results as in Example 1 were obtained under the same conditions as in Example 1 except that a sizing agent having the following composition was used. Urethane emulsion (30% solids)
10.0% by weight Octyldimethylammonium ethosulfate (solid content 50%) 0.6% by weight γ-methacryloxypropyltrimethoxysilane 0.3% by weight Stearic acid/tetraethylenepentamine condensate (solid content 30%) 0.1% by weight Glacial acetic acid 0.1 Weight % Water Residual Amount Examples 3 to 5 The same results as in Example 1 were obtained under the same conditions as in Example 1, except that a sizing agent having the following composition was used.
