摘要： PURPOSE:To improve the strength and the electrolyte preservative property of a separator for a storage battery, by including a synthetic fiber with the water absorption property to a glass fiber at a specific content, and making the tensil strength and the buckling strength of the fiber at a specific value or above. CONSTITUTION:A separator for a storage battery is formed of a glass fiber including a synthetic fiber with the water absorption property, and the ratio of the content of the synthetic fiber is set 6-18 wt% or above of the whole fibers composing the separator. And, the tensil strength is made at 800g/15mm wideX1mm thick or more, and the buckling strength is made 70g/10mm wideX1 mm thick or more. The glass fiber is formed of mainly fibers of mean diameter 0.7 to 2mum, and furthermore, the electrolyte preservative property of the separator is made 1.2g/cc or more. Therefore, the ratio of the synthetic fiber with the water absorption property is regulated properly, the mechanical strength of the separator is made to be sufficient when an assembling unit is used in the battery assembling, and moreover, the electrolyte preservative property and the electrolyte absorption swelling property can be improved.

摘要： PURPOSE:To increase strength, electrolyte absorbing capacity, electrolyte retention capacity, and heat sealing ability by forming a separator with glass fiber, water absorbing synthetic fiber, and thermoplastic organic fiber. CONSTITUTION:A separator consists of glass fiber, water absorbing fiber, and thermoplastic organic fiber. As the glass fiber, alkali-containing glass fiber having good acid resistance is preferable. As the water absorbing fiber, acrylic fiber in which water absorption treatment is applied on the surface is preferable. As the thermoplastic organic fiber, polyester is suitable from the standpoint of acid resistance and oxidization resistance. Preferable mixing ratio is 30-79wt% glass fiber, 1-20wt% water absorbing fiber, and 20-60wt% thermoplastic organic fiber. The contents of water absorbing fiber and thermoplastic organic fiber are preferable to control to 70wt% or less based on the total fiber weight.

摘要： PURPOSE:To increase mechanical strength, productivity in battery assembly, electrolyte retention capacity, and swelling capacity after electrolyte absorbing by containing glass fiber, synthetic fiber having water absorption property, and acrylic binder which bonds the above fibers. CONSTITUTION:Fibers constituting a separator are glass fiber and synthetic fiber having water absorption property, and these fibers are strongly bonded with acrylic binder. As the glass fiber, alkali-containing glass fiber having good acid resistance is preferable. As the synthetic fiber having water absorption property, acrylic fiber in which water absorption treatment is applied on the surface is preferable. As the acrylic binder, conventional acrylic liquid binder can be used. 1-6wt% synthetic fiber and 0.5-5wt% acrylic binder based on the glass fiber are used.

摘要： PURPOSE:To improve liquid maintainability and liquid absorptivity, by using glass fibers in the main, containing thermoplastic organic fibers, and attaching fibers to themselves with water-glass adhesives. CONSTITUTION:Glass fibets are used in the main, thermoplastic organic fibers are also contained, and the fibers are attached to themselves with water-glass adhesives. Separators in a storage battery, whose main constituents are glass fibers, are preferrably composed of main smalldiameter glass fibers of 2mum or less in average diameter, 0-35 wt % large-diameter glass fibers of 10-30mum in average diameter, and 0-30 wt % middle-diameter glass fibers above 2 mum and below 10 mum in average diameter. The suitable content of the small- diameter glass fibers is 60 wt % or more out of the whole glass fibers, especially 65wt % or more being preferrable. water glass, and besides inorganic adhesives containing water glass are appropriate for the water-glass adhesives. Because the glass fibers hence being in the main, liquid absorptivity and liquid maintainability can be improved, particularly the liquid maintainability becoming excellent under a pressurized atmosphere.

摘要： PURPOSE:To increase electrolyte retention capacity and electrolyte absorbing capacity in addition to high strength and hardness by melt-bonding glass fibers of a separator for storage battery made of glass fiber alone. CONSTITUTION:Glass fibers mainly consist of fine glass fibers having a mean diameter of 2mum or less, and contain 0-35wt% thick glass fibers having a mean diameter of 10-30mum and 0-30wt% medium-fine glass fibers having a mean dismeter exceeding 2mum but less than l0mum. A preferable mean length of the fine glass fibers is 7-50mm and particularly 10-40mm. Alkali-containing silicate glass fiber is preferable. Relatively long fine glass fibers and midium-fine glass fibers are mixed to thick glass fibers having a given length in a proper ratio, and the mixture is dispersed with a pulper, then a glass fiber sheet is formed by a wet-type paper making process. The glass fiber sheet is dried and heated to melt a part of glass fiber. Thereby, glass fiber itself is melt- bonded each other. This heattreatment is performed at 650+ or -50 deg.C for 1-5 minutes, preferably at about 650 deg.C for 2 minutes.

摘要： PURPOSE:To improve the liquid holding and sucking performance by employing synthetic fiber having water absorbing power in a battery separator containing glass fiber and synthetic fiber. CONSTITUTION:Glass fiber and water absorbing synthetic fiber are employed for constituting a separator. Alkali-containing glass fiber is used for this purpose because glass fibers are stuck together without using bonding agent. The content of glass fiber is higher than 60wt% of the total weight of fiber constituting the separator. Water absorbing synthetic fiber is employed by applying water absorbing treatment onto the surface of non-water absorbing synthetic fiber. In such a manner, liquid holding and sucking performance of separator can be improved while mechanical strength can be improved through reinforcing effect of synthetic fiber.
