Dry-mixed mortar admixture containing industrial protein powder and dry-mixed mortar
The invention provides a dry-mixed mortar admixture containing industrial protein powder and dry-mixed mortar, and belongs to the technical field of dry-mixed mortar admixtures. The dry-mixed mortar admixture comprises 5-10% of an air entraining agent, 0-3% of a thixotropic agent, 2-6% of a thickening agent, 6-14% of a water-retaining agent, 10-20% of modified industrial protein powder, 5-16% of a retarder and the balance of filler. The modified industrial protein powder is introduced into a common dry-mixed mortar admixture and is mixed with a small amount of the water-retaining agent according to a certain proportion, so that the dry-mixed mortar admixture is obtained, and the water retention requirement of the dry-mixed mortar can be met; meanwhile, the addition amount of the air entraining agent in the dry-mixed mortar admixture can be reduced, the production cost is reduced, the state of the dry-mixed mortar is improved, and the wrapping property and softness of the dry-mixed mortar are improved.
本发明提供了一种含有工业蛋白粉的干粉砂浆外加剂及干粉砂浆，属于干粉砂浆外加剂技术领域。本发明所述干粉砂浆外加剂包含引气剂5‑10％、触变剂0‑3％、增稠剂2‑6％、保水剂6‑14％、改性工业蛋白粉10‑20％、缓凝剂5‑16％、余量为填料。本发明通过在普通干粉砂浆外加剂中引入改性的工业蛋白粉，使其与少量保水剂按一定比例混合配置得到的干粉砂浆外加剂，不但可以满足干粉砂浆对保水的需求，同时还可以减少干粉砂浆外加剂中引气剂的添加量、降低生产成本、改善干粉砂浆的状态、提高干粉砂浆的包裹性和柔和度。
