Tackifying and water-retaining agent for recycled aggregate mortar and preparation method of tackifying and water-retaining agent
The invention discloses a tackifying and water-retaining agent for recycled aggregate mortar and a preparation method of the tackifying and water-retaining agent, relates to the technical field of preparation of the tackifying and water-retaining agent for the mortar, and solves the problems that the tackifying and water-retaining agent for the recycled aggregate mortar in the prior art is large in dosage and needs to entrain air to influence the strength of the mortar, the tackifying and water-retaining agent comprises welan gum, xanthan gum and polyethylene glycol 400, the mass part of the welan gum is 35 to 40 parts, the mass part of the xanthan gum is 60 to 65 parts, and the mass part of the polyethylene glycol 400 is 1 to 1.5 parts; through an M10 plastering mortar proportioning test, the use amount of the tackifying water-retaining agent is only 0.02%-0.03%, and the water retention rate can reach 90%-96%; compared with a cellulose ether mortar tackifying water-retaining agent, the use amount is reduced by 60%-80%, the tackifier cost is saved, the tackifier can be used trustingly without air entraining, and the mortar strength is not affected.
一种再生骨料砂浆用增粘保水剂及其制备方法，涉及砂浆增粘保水剂制备技术领域，解决了现有技术的再生骨料砂浆用增粘保水剂用量大和需要引气影响砂浆强度的问题，包括：温轮胶、黄原胶和聚乙二醇400，其中，温轮胶、黄原胶和聚乙二醇400三者的质量份数分别为：温轮胶为35‑40，黄原胶为60‑65，聚乙二醇400为1‑1.5；通过M10抹面砂浆配比试验，本发明的增粘保水剂使用量仅为0.02％‑0.03％，就可使保水率可达90％‑96％；与纤维素醚类砂浆增粘保水剂相比减少60％‑80％的用量，节省了增粘剂成本，不引气可以放心使用，不影响砂浆强度。
