随着我国汽车工业的飞速发展，废旧轮胎的合理处置成为极受社会关注的一大环境问题。据不完全统计，仅2006年一年我国汽车轮胎的废弃量就超过1亿条，而在这些废旧轮胎中，只有50％左右得到了合理的回收和利用。废旧轮胎的出现不仅严重污染了我们生活的环境，而且也是一种极大的资源浪费，如果堆积在一起还极易引起火灾，其不完全燃烧会放出碳氢化合物和有毒气体，火焰也很难扑灭。With the rapid development of my country's automobile industry, the reasonable disposal of waste tires has become a major environmental issue that has attracted the attention of the society. According to incomplete statistics, in 2006 alone, the amount of discarded automobile tires in my country exceeded 100 million pieces, and among these waste tires, only about 50% were properly recycled and utilized. The appearance of waste tires not only seriously pollutes our living environment, but also is a great waste of resources. If they are piled up together, they can easily cause fires. Their incomplete combustion will release hydrocarbons and toxic gases, and the flames are also very difficult. put out.
当前政府提出了建筑工程的节能号召，原有建筑工程中用于保温功能的聚氨脂等原料来源于石油，而将废旧轮胎机械粉碎后，取代砂来制备水泥砂浆，使得这种水泥砂浆具有轻质，保温等独特的优点，不仅能满足当前建筑工程对保温的要求，而且处理掉大量的废旧轮胎，起到利废为宝的作用。都来源于目前国内外还没有关于这方面的报道。The current government has put forward the call for energy saving in construction projects. The raw materials such as polyurethane used for heat preservation in the original construction projects come from petroleum, and the waste tires are mechanically crushed to replace sand to prepare cement mortar, which makes this cement mortar have The unique advantages of light weight and thermal insulation can not only meet the thermal insulation requirements of current construction projects, but also dispose of a large number of waste tires, which can turn waste into treasure. They all come from the fact that there are no reports on this aspect both at home and abroad.

本发明中，减水剂是塑化减水组分，是建筑材料中常用的成分，它是一种表面活性剂，加入水泥浆体中后，能吸附在水泥颗粒表面，使原本呈絮凝状的浆体结构解体，释放出絮凝结构中包裹的自由水，从而大幅度增加浆体的流动性，或在减水情况下，增加浆体强度。引气剂也是建材中常用的组分，它能使水泥砂浆在搅拌过程中引入大量微小密闭气泡，改善水泥砂浆的和易性与耐久性，降低水泥砂浆的表观密度和热导率，改善水泥砂浆的热工性能。乳胶粉是一种有机胶凝材料，掺加到保温砂浆中，能明显改善水泥砂浆的粘聚性和保水性，改善橡胶粉、砂与水泥浆体之间的粘结力，在施工过程中不致下落，降低反弹率，提高工效，减少浪费；降低水泥砂浆的干燥收缩率。纤维素醚是保水组分，也是建材中常用组分，它能显著改善水泥砂浆的和易性，降低水泥砂浆的分层度。该水泥砂浆的稠度为80mm左右，分层度为20mm左右，干表观密度达850kg·m-3，热导率为0.08W·m-1·K-1左右，软化系数达1.00，28d抗折强度达410KPa，28d抗压强度达640KPa，线性收缩率为0.09％左右，56d压剪粘结强度达120KPa。In the present invention, the water-reducing agent is a plasticized water-reducing component, which is a commonly used component in building materials. It is a surfactant. After being added to the cement slurry, it can be adsorbed on the surface of cement particles, making the original flocculated The disintegration of the slurry structure releases the free water wrapped in the flocculation structure, thereby greatly increasing the fluidity of the slurry, or increasing the strength of the slurry in the case of water reduction. Air-entraining agent is also a commonly used component in building materials. It can make cement mortar introduce a large number of tiny airtight air bubbles during the mixing process, improve the workability and durability of cement mortar, reduce the apparent density and thermal conductivity of cement mortar, and improve Thermal properties of cement mortar. Latex powder is an organic gelling material, which can significantly improve the cohesion and water retention of cement mortar when added to thermal insulation mortar, and improve the bonding force between rubber powder, sand and cement paste. It will not fall, reduce the rebound rate, improve work efficiency and reduce waste; reduce the drying shrinkage of cement mortar. Cellulose ether is a water-retaining component and a commonly used component in building materials. It can significantly improve the workability of cement mortar and reduce the delamination of cement mortar. The consistency of the cement mortar is about 80mm, the degree of stratification is about 20mm, the dry apparent density is 850kg·m -3 , the thermal conductivity is about 0.08W·m -1 ·K -1 , the softening coefficient is 1.00, and the 28d resistance The folding strength reaches 410KPa, the 28d compressive strength reaches 640KPa, the linear shrinkage rate is about 0.09%, and the 56d compressive shear bond strength reaches 120KPa.
