This paper relates to a method for making glass and glass delicates hydrophilic. Therefore, one of the zero-asbestos substitutes for which legal regulations require alternatives is glass*. However, fine glass lacks the characteristics that asbestos possesses, such as water resistance, water retention, and prevention of solid matter from flowing out. The present inventors glass acid JI! As a result of intensive research on 5 different treatment methods that have properties similar to those of asbestos, we discovered a hydrophilic agent that turns glass into water.
In other words, the present inventors have succeeded in providing a glass ##l that makes it easy for G2x fibers to get wet with water, has good dispersibility, and has excellent water retention properties.

@ is a hydrogen atom or a methyl group, X beam, *NaaK. It has been found that the desired objective can be achieved by treating glass and glass*aiv with NH4 or 1% adducts of organic amines, where 1% represents any integer. Furthermore, after shocking the glass or lath delicate with a water-soluble polymer containing an alkali metal salt and a sodium carboxylic acid group (hereinafter a mixed system of the two is referred to as a composite hydrophilic agent) among the hydrophilic agents, It has been found that further hydrophilicity can be obtained by treatment with an aqueous solution containing metal ions with a valence of two or more. The hydrophilizing agent represented by the general formula (1) used in this study is a new compound, and is synthesized by the following 5K process. That is, a silane compound (seal) in which one organic group containing one alkoxy group and one mercapto group represented by the following general formula is bonded, and (meth)acrylic acid or a derivative thereof.

It can be obtained by neutralizing each with a primary amine, a tertiary amine, and a tertiary amine.The alkyl group (R1) of compound (1) is preferably a lower alkyl group, such as a methyl group, an ethyl group, a propyl group, etc. The alkylene group (Rf) of the compound (1) is preferably a lower alkylene group, such as an ethylene group, a propylene group, a butylene group, a pentamethylene group, or a pentamethylene group. The amine used in the synthesis of the salt is preferably a lower amine, such as methylamine, dimethylamine, trimethylamine, ethylamine, diethylamine, triethylamine, ethanolamine, diethanolamine, triethanolamine, etc. Addition reaction The reaction is carried out in water, an organic solvent, or a water-containing organic solvent.When adding (meth)acrylic acid, any of the above solvents can be used.The solvents used in this case include methyl alcohol,

In addition, when using an alkali metal salt of addition reaction EC meth)acrylic acid, it is of course possible to use an organic solvent that simultaneously reacts with these compounds and the compound (1). A person who is strict is #Ii more beautiful. When the addition reaction is carried out in an aS medium, the initiator used in the addition reaction is preferably an organic peroxide that is usually used as an initiator for radical polymerization, such as cumene peroxide, tsuku ζ ruberoxide, peroxide, etc. Examples include benzoyl and azobisisobutyronitrile. When the addition reaction is carried out in water or a water-containing organic solvent, 1
Redox initiators that are usually used as radical polymerization initiators are preferred, such as hydrogen peroxide-ferrous sulfate, ammonium persulfate-sodium bisulfite, calcium persulfate-sodium bisulfite, potassium persulfate-(β-dimethylaminopolymer). The temperature and time of the addition reaction vary depending on the type of initiator, and generally organic peroxides require a higher temperature, but for example, in the case of benzoyl peroxide, the temperature and time of the addition reaction differs depending on the type of initiator. The addition reaction was completed in 8 hours. Further, in the case of a redox initiator, the addition reaction can be carried out in several hours at a temperature of room temperature to 50°C.

In the case of hydration, a solution of the above composite hydrophilic agent is coated or impregnated with glass fiber laK to a bath liquid containing at least the hydrophilic agent represented by the formula (1). In the sizing agent application device used in the glass fiber spinning process, a large amount of sizing agent rcil water-improving agent or composite hydrophilic agent is added, and these hydrophilic agents or composite water-breaking agents are impregnated together with the sizing agent. Process heating IIE
The amount of the hydrophilic agent or composite hydrophilic agent applied during printing in the image process is 101 to 1 ◎ by weight relative to the glass fiber, and preferably 11 to 1 ◎ by weight from the viewpoint of performance and economy. The hydrophilization mechanism of the hydrophilic agent is that the hydrophilic agent is hydrolyzed in an aqueous solution, the alkoxy group becomes a silanol, and the 81-〇H group of the glass fiber is dehydrated and condensed to heat-dried W#, resulting in a delicate glass fiber. While forming a covalent bond with the surface, the poly2 residue of the (meth)acrylic acid derivative has hydrophilicity, which is thought to improve the hydrophilic dispersibility and water retention of the glass fiber. In addition, the hydrophilizing mechanism of the composite hydrophilizing agent is the same as that of the above-mentioned hydrophilizing mechanism of the hydrophilizing agent contained therein.
Although they are considered to be the same, ++ ++ ←→ metal ions with a valence of more than 2 (e.g. C@all, A
When treated with an aqueous solution of zF, etc.), for example, if the metal ion is Ca, it is thought that a reaction of, for example, a spring water-forming agent will occur. This means that the water-soluble polymer is grafted onto the glass am via the hydrophilic agent, and furthermore, the COONa groups in the Kll hydrating agent and the Coo)% in the water bathing polymer, Motooka Shi It is thought that a cross-linking reaction occurs in s'1lic due to the ion exchange reaction with CaL ions.As a result, the gel-structured hydrophilic membrane forms an ionic bond with the hydrophilic agent and the bond between the hydrophilic agent and the glass surface. It is thought that it is strongly bonded to glass fibers through covalent bonds, and that the hydrophilicity 1 dispersibility and water retention of %Glass III #I are further improved.
When glass fiber treated with a hydrophilic agent is used as a (partial) substitute for asbestos in the production of asbestos-cement boards, Ca derived from cement is already contained in the system, so it is There is no need for pretreatment with an aqueous solution containing Kaede ions. Therefore, glass fibers treated with a hydrophilic agent or a composite hydrophilic agent can be advantageously applied to the field of paper making such as glass paper, and as an alternative to asbestos in the production of asbestos cement boards, gypsum slag boards, pulp cement boards, etc. I can do it. Furthermore, the present invention can be applied not only to glass fibers but also to glass plates. When a drop of water is dropped on a glass plate treated with the hydrophilizing agent of the present invention or on a glass plate treated with an aqueous solution of divalent or higher metal ions after coating, the water droplet disappears at once. As expected from the above mechanism of hydrophilicity, the glass treated with the hydrophilic agent and composite hydrophilic agent of the present invention has the following properties:
Semi-permanent in water. The effect of the hydrophilic agent of the present invention is demonstrated by a glass fiber sedimentation rate test and a droplet of water falling on glass 111, and the contact angle thereof is small. The sedimentation rate test was carried out by placing water or an aqueous solution system, such as a polyethylene oxide (PIO) aqueous solution or carboxymethylcellulose ((1 part MO) aqueous solution, etc., in a 500cc measuring cylinder [500 (le) and trapping a hydrophilic agent in it. Glass treated with tax
Insert the glass wire* that is not treated with a spring water agent, and add 100a from AQ96G in a 5oocc graduated cylinder! Measure the settling time. In this case, the glass HI koji treated with a hydrophilic agent is well adapted to water, and its precipitation time is longer than that of fibers that are not treated with a hydrophilic agent. On the other hand, the effect of the hydrophilicity of the glass ms to which the composite hydrophilizing agent is attached can be confirmed by the same sedimentation rate test as above, except that the cement supernatant liquid, which already contains Ca++ ions, is used as the test solution. The following is about the F example.
