Natural adhesives and latex reclaimed adhesives are natural substitutes for natural rubber to produce rubber products and reduce the cost of raw materials. However, they have great differences from raw materials to their uses. Among them, natural rubber used for floor replacement is used to replace various kinds of natural rubber to produce various kinds of high elasticity. Molded rubber products reduce production costs. Calcium carbonate is one of the most commonly used fillers when using floor adhesives to produce rubber products. Its amount of usage directly affects the physical and mechanical properties of the natural rubber products that fall on the floor.
Calcium carbonate is low in price and stable in performance. It can be used in the production of natural rubber products that can increase the volume of products, reduce the amount of rubber used, and reduce the production cost. It can also improve the gloss and wear resistance of rubber products; the greater the amount of calcium carbonate, The lower the cost of landing natural rubber products, but it does not mean that the lower the amount of calcium carbonate in the natural rubber products, the better.
In the actual production, the indicators of the natural rubber products falling on the floor will change continuously with the increase of the calcium carbonate dosage. Generally, the greater the calcium carbonate filling amount, the greater the hardness and the settling stress of the natural rubber products falling on the floor. The permanent deformation and tearing strength become greater, and the tensile strength and elongation at break of the grounded rubber products are reduced. Therefore, the use of calcium carbonate will reduce the mechanical properties of the natural rubber that lands on the floor. The rubber product manufacturer will fill carbonated natural rubber products in the floor. When calcium is used, its amount should be increased as much as possible to meet the requirements of its mechanical properties, but it cannot be blindly filled to reduce the cost of rubber.
Under the premise of ensuring product quality, in order to reduce the cost of more natural rubber products landing, increase the amount of calcium carbonate, rubber manufacturers can also use the right amount of resorcinol and hexamethylenetetramine on the modification of calcium carbonate (between The amount of hydroquinone is about 1.5 parts, and the amount of hexamethylenetetramine is about 2.0 parts), which improves the calcium carbonate reinforcing property, increases the amount of calcium carbonate filled in the natural rubber products in the floor, and improves the tear strength of natural rubber products. , Permanent deformation, improve the mechanical properties of the natural rubber products landing, and significantly reduce the cost of raw materials.
Compared with the natural rubber of various brands, the price of the natural rubber is lower. To replace the standard natural rubber, various molded rubber products can significantly reduce the cost of raw materials under the premise of ensuring the quality of the rubber products. The tensile strength is high and the wear resistance is good. Can directly replace the standard one, standard two production of various rubber products, such as engineering rubber, tire tires, conveyor belts, bridge bearings and so on.
