Examples include aminovinyltriethoxysilane, 3-aminocyclohexylethyltriethoxysilane, p-aminophenyltriethoxysilane, and N-(β-aminoethyl)-γ-aminopropyltrimethoxysilane. Among these, ethoxysilane is preferable to methoxysilane in terms of compatibility with glass fibers. In addition, carboxylated styrene-butadiene latex (hereinafter referred to as C-
(called SBR) has a carboxylation rate of 0.1~
Although products with a concentration of 3.5% are commercially available, a high carboxylation rate is required in order to improve affinity and adhesion with glass fibers and improve the reinforcing effect of rubber, and a range of 2.5 to 3.5% is required. This will be based on the following. In addition, the styrene content of C-SBR is
The content should be in the range of 20% to 30%; if it is less than this range, the glass fiber after treatment will be too soft, and if it exceeds this range, it will become too hard, which is inappropriate. It is preferably in the range of 20% to 25%.

In addition to SBR, it is preferable to use various auxiliary materials such as surfactants and lubricants that are normally used in sizing agents. Specifically, various nonionic and cationic surfactants can be used as the surfactant. However, from the viewpoint of liquid stability, nonionic ones are preferred. Furthermore, the use of a lubricant improves processability, and various lubricants such as animal, plant, mineral, etc. can be used. Among these, mineral-based materials are most preferred in terms of liquid stability and the like.
