The present invention relates to a glue material for fiber walls. Compared to traditional earth and sand walls, fiber wall materials (1) have a wider variety of types, (2) have a softer feel on the coated surface, and (3)
It has the following advantages: it is easy to handle and does not require skilled application techniques; and (4) performance can be imparted according to the purpose by appropriately selecting aggregates, colorants, and adhesives. Therefore, demand is currently increasing rapidly, mainly for general housing. Fiber wall materials generally consist of aggregate, coloring material, and glue, and the following materials are used for each. Aggregates: Silica sand, cold water sand, wood flour, pulp, cotton flour, charcoal karoo, clay, gypsum, etc. Gluing materials: Carboxymethyl cellulose sodium salt (Na-CMC), hydroxypropyl methyl cellulose (HPMC), polyvinyl alcohol (PVC) and Mixture thereof Coloring agent: pigment, clay Na- used as glue for the fiber wall
CMC, HPMC, PVA and their mixtures are
Several drawbacks have been pointed out in actual use. For example, Na-CMC has disadvantages such as becoming insoluble in water, gelling, and deteriorating when acidic substances or substances containing polyvalent metal ions coexist.
Therefore, when Na-CMC is used as a glue material,
If the base is mortar or gypsum plaster,
Base substitution occurs between Na−CMC and metal ions (mainly Ca 2+ ions), causing poor adhesion.
Furthermore, when the aggregate contains acidic substances, alkaline substances, or polyvalent metal ions, poor adhesion and a decrease in the strength of the wall itself occur for the same reasons as above. Even when HPMC and PVA are used, there is stickiness during application, large sag, and air bubbles generated during kneading remain on the applied surface, which causes a decrease in the surface strength of the wall after drying. The present inventors conducted various studies to solve these problems, and found that sulfoethyl cellulose sodium salt (Na-SEC) is 1) soluble in water with a low degree of substitution, 2) has a high surface tension, and is foamable. Although it has the same basic physical properties as Na-CMC, such as no oxidation and thixotropic aqueous solution, it has better stability against acids, alkalis, and polyvalent metal ions than Na-CMC. The present invention was completed by paying attention to this and successfully obtaining a glue material for fiber walls that does not have the conventional drawbacks. The present invention uses 100 parts by weight of aggregate and Na-SEC1 to 30 parts by weight.
The gist is a glue material for fiber walls consisting of parts by weight. Na-CMC changes to water-insoluble acid form H-CMC under strongly acidic conditions of PH3 or higher, and its water-soluble viscosity rapidly decreases, whereas Na-SEC changes to water-soluble acid form H-CMC. It changes to SEC and does not cause clay deterioration even under strongly acidic conditions of PH3 or higher. Also,
In an aqueous solution containing polyvalent metal ions, Na-CMC becomes water-insoluble or gels due to a type of cation exchange, whereas Na-SEC is stable against most polyvalent metal ions. It has excellent properties. When the degree of etherification of Na−SEC is less than 0.2, the solubility in water decreases, and when the degree of etherification is 1.2, the solubility of Na−SEC in water decreases.
The degree of etherification is preferably from 0.2 to 1.2 as a paste material for fiber walls, since the thixotropy, which is a solution physical property unique to SEC, is reduced. The amount of Na-SEC added in the present invention is 100% of aggregate
The amount is 1 to 30 parts by weight, and if it is less than 1 part by weight, the fluidity and adhesion of the adhesive will be poor, and if it is more than 30 parts by weight, it will be sticky and workability will be reduced.
No particular effect can be expected. As the aggregate, conventionally used aggregates can be used. The Na-SEC glue material of the present invention has good adhesion, abrasion resistance, and sticking resistance even when the aggregate or coloring material contains acidic substances or polyvalent metal ions, or even when the base is mortar or gypsum plaster. In addition to exhibiting excellent properties in terms of hardness and application workability, it also does not generate air bubbles when mixed with water.
Unlike HPMC and PVA, it does not reduce the surface strength of the wall due to air bubbles, providing superior effects not seen with conventional adhesives. Next, examples of the present invention will be given. Example 1 Synthesis of Na-SEC-A: 10.4 g of powder pulp (ER-4500) and 15.4 g of 44% NaOH aqueous solution (NaOH/C1 CH 2 CH 2 SO 3 Na molar ratio
2.6, water/cell weight ratio 0.83) was stirred with 100 g of isopropyl alcohol (isopropyl alcohol/cell weight ratio 9.6) at 5°C for 1 hour to make alkali cellulose, and then 5.5 g of β-chloroethanesulfonic acid sodium salt ( C1
