に剥離が進み、強度がかなり低下した。<Conventional technology> Conventionally, a compressed fiber base material formed into a hollow shape is impregnated with a thermosetting resin, and then hardened at room temperature or under heating.The outer surface of the lightweight structure is coated with liquid thermosetting resin and cement. It was created by coating and surrounding a nonflammable material obtained by kneading mortar, glass fiber, and hydrophilic resin (for example, polyvinyl alcohol). (Utility Model Publication No. 63-4721) The above structure has a hollow compressed fiber base material and the outside is made of fire-resistant material, so it has been evaluated as a lightweight and fire-resistant roofing material, but the surface coating Because the material contains cement mortar, its moisture has a negative effect on the adhesion with the thermosetting resin impregnated into the internal compressed fiber base material, and although the hydrophilic resin is present, the surface adhesion is It was not sufficient and peeling progressed over time, resulting in a considerable decrease in strength.

かできた。<Means for Solving the Problems> The present invention has been made in view of the above-mentioned problems, and solves the main cause of inhibiting the adhesion between the hollow compressed fiber base material and the fire-resistant material applied thereto. Moisture in cement mortar,
Considering that even the presence of a hydrophilic resin does not strengthen the adhesive strength, we stopped mixing the hydrophilic resin and stopped using the conventional method of cement mortar. A suitable amount of a liquid thermosetting resin and a curing agent are added and mixed into a mixture with gravel, and the fire-resistant material obtained by kneading these is mixed around a hollow compressed fiber base material impregnated with a liquid thermosetting resin. The scales were bonded and cured using a liquid thermosetting resin, making it possible to create a durable fire-resistant building material with extremely high adhesion.

、耐火性建築材を得る。As a result of repeated experiments, it was found that the manufacturing conditions described below are more suitable. When the cement is 100 parts by weight, the aggregate is 100 to 300 parts by weight, the liquid thermosetting resin (for example, polyester resin or epoxy resin) is 10 to 30 parts by weight, and 0.5 parts by weight of a hardening agent are added. 1~0
．． It is necessary to be within the range of 3 parts by weight 2. Experiments have shown that if the aggregate exceeds 300 parts by weight of cement and 100 parts by weight, the connection is weak, and if it is less than 100 parts by weight, the cost is high. Moreover, if the thermosetting resin is less than 10 parts by weight, a fire-resistant material as a fluid mixture cannot be obtained.
If it exceeds 30 parts, admixtures will be present, and the fire resistance and deformability of the resulting building material will become a problem, and from the standpoint of curing properties and economy, a suitable amount of curing agent is 0.1 to 0.3 parts by weight. be. As the curing agent for the curable resin = 3-, Permec N (manufactured by Showa Kobunshi Co., Ltd.) is used, and cobalt naphthenate is preferably added as a curing accelerator, with an appropriate amount of 0.05 to 0. .1 part by weight. To 100 parts by weight of the cement h described above, 100 to 300 parts by weight of sand, aggregate, and if necessary gravel aggregate, and further 10 to 30 parts by weight of liquid thermosetting resin are added to add a curing agent and, if necessary, is kneaded with a curing accelerator to obtain a fire-resistant building material.
以上の耐火性建築材を後記するように、相互連結、係合

。<Function> The fire-resistant building material obtained by the above manufacturing method is obtained by impregnating and curing the compressed fiber base material serving as the core material with a liquid thermosetting resin,
Since this is surrounded and hardened with fireproof materials such as cement 1~, thermosetting resin, and hardening agent without the presence of water, the adhesion between the core material and the fireproof material as the outer circumferential material is completely achieved, unlike conventional No peeling was observed at all as in the case of adhesion using water-based resins, and the cement I~ was cured and hardened in the outer enclosure.
