The amount of rubber in the construction industry is second only to the automotive industry, especially waterproof materials, such as rubber waterproofing membrane sheets, waterproof coatings, latex asphalt, waterproof sealants, etc. Tire reclaimed rubber is a rubber material obtained by recycling waste tires and processing them, which has the characteristics of good performance, low price and easy processing, and is widely used in the construction industry to reduce manufacturing costs, improve performance and extend service life.
1. Application of tire reclaimed rubber in waterproofing membrane
The waterproofing membrane is required to have certain mechanical strength, elongation, tear resistance and flexibility, and can resist water infiltration and penetration; Tire reclaimed rubber has good elasticity and durability, which can meet the performance requirements of waterproofing membranes and can be used to prepare waterproofing membranes. For example, tire reclaimed rubber is used in roofing waterproofing materials such as waterproofing membranes and coatings, which can provide good waterproof performance and durability, and effectively prevent moisture penetration.
2. Application of tire reclaimed rubber in building materials
Tire reclaimed rubber has good elasticity, wear resistance and impact resistance, and can be used as an additive in concrete production. Adding tire reclaimed rubber to concrete can improve the toughness and crack resistance of concrete, and improve the compressive strength, bending strength and durability of concrete. Under normal circumstances, the amount of tire reclaimed rubber in concrete is among 5% and 20%.
Tire reclaimed rubber can be used for the processing of rubber bricks and rubber floors. Reclaimed rubber has good hardness, tensile strength and wear resistance, which can meet the needs of various applications such as rubber floor tiles, and the finished rubber floor tiles have good wear resistance and anti-slip properties, and are widely used in schools, hospitals and other occasions.
3. Application of tire reclaimed rubber in sealing materials
Tire reclaimed rubber has similar physical properties to new rubber, good elasticity, wear resistance, aging resistance, the price is much lower than natural rubber, styrene-butadiene rubber, butadiene rubber, etc., used in the production of sealing products such as building door and window sealing strips, sealing rings, density rubber, etc., which can effectively reduce the cost of raw materials, and can improve the processing technology performance of rubber and the tear resistance and aging resistance of finished products.
When using tire reclaimed rubber to produce sealing products, it is recommended to choose tire reclaimed rubber without impurities that is close to the physical property requirements of the product, and adjust the formula according to the performance characteristics of the reclaimed rubber and the physical property requirements of the product, especially the vulcanization system and the reinforcing filling system. When tire reclaimed rubber and raw rubber such as natural rubber and styrene-butadiene rubber are used together to produce sealing rubber products in the construction industry, it is necessary to ensure that the rubber raw materials are mixed evenly, and the production process conditions such as temperature and pressure are appropriately adjusted to improve the quality of the finished product.
4. Application of tire reclaimed rubber in sound insulation and shock absorption materials
Tire reclaimed rubber has good elasticity and aging resistance, and is widely used in the production of sound insulation and shock absorption materials in the construction industry to reduce the cost of raw materials. When using tire reclaimed rubber to produce rubber sound insulation materials and shock absorbing products, it is necessary to evaluate the physical and chemical properties of the reclaimed rubber used to meet the requirements of sound insulation and shock absorbing materials, focus on the elasticity, aging resistance, temperature resistance and durability of the reclaimed rubber, consider the compatibility of reclaimed rubber and original rubber, reasonably design the formula, and reduce more costs on the premise of meeting the needs of finished products.
Tire reclaimed rubber is widely used in the construction industry, which can not only improve the performance of building materials, but also promote environmental protection and sustainable use of resources. When using reclaimed rubber to reduce the cost of rubber products, it is necessary to ensure that the reclaimed rubber meets the relevant safety and quality standards, and determine the proportion and addition method of tire reclaimed rubber according to the specific product requirements and the quality of the reclaimed rubber, and appropriately adjust the production formula and production process conditions, so as to further optimize the quality of the finished product while reducing costs.
