Abstract

A diatomite calcium plastic composite board and a production method thereof, the main points of which are that it includes the following components: PVC resin, heavy calcium carbonate, nanoscale heavy calcium carbonate, plasticizer, diatomite, straw Flour or wood flour, heat stabilizer, stearic acid, polyethylene wax, paraffin wax; after mixing and drying the above components in a certain proportion, extrude the plate structure through the extruder according to the mold, and then vacuum shape and cut , Sanding the bottom surface and the surface, the surrounding mortise and deep processing of the surface can become the finished floor. The present invention adds a small amount of nano-scale heavy calcium carbonate and diatomite to fully fill between the large particles of heavy calcium carbonate, thereby forming a complete package for PVC resin particles and increasing the specific surface area. Its reactivity increases; its hardness is high and its plasticity is strong; the nanoparticles in the nanocomposite material can prevent the formation of crystals, therefore, it can greatly reduce the weight and improve the thermal conductivity.

Description

technical field

[0001] The invention relates to the technical field of civil furniture and decorative boards, in particular to a diatomite calcium-plastic composite board. Background technique

[0002] With the continuous development of society and the continuous progress of science and technology, people's living standards and quality requirements are also constantly improving. As we all know, in recent years, the winter heating method has gradually changed from the traditional casting radiator heating method to a diversified heating method. For example: the "geothermal" heating method of aluminum-plastic pipes, the air-conditioning hot air heating method, the electric heating method, and stainless steel or aluminum alloy heaters, among which the "geothermal" heating method of aluminum-plastic pipes is the most popular. The above-mentioned "geothermal" heating method has indeed relatively beautified the indoor environment and relatively improved the indoor space utilizatio...

Examples

example 1

[0041] Input 1000kg of raw materials, including 250kg of PVCSG-5PVC resin; 435kg of 500-600 mesh heavy calcium carbonate (CaCO3); 5kg of 50-100nm nanoscale heavy calcium carbonate (CaCO3). 100kg of 325 mesh diatomite; 70kg of 60 mesh straw powder or wood powder; 18kg of calcium zinc composite stabilizer, 12.5kg of stearic acid; 12kg of polyethylene wax; Put in 16.5kg of semi-refined paraffin wax; put in 33kg of acrylic copolymer ACR as a processing aid; put in chlorinated polyethylene plasticizer and toughening agent 40kg; put in PVC calcium-zinc composite stabilizer 20kg; put in titanium dioxide color material 8kg .

[0042] Since the water content of heavy calcium carbonate (CaCO3) is 2-8%, generally 920-980 kg of products can be produced per 1000 kg of raw materials.

[0043] Production method and process flow:

[0044] 1. First mix PVC resin, composite stabilizer or rare earth composite stabilizer, heat and dry when the temperature reaches 50-80°C, then add processing ai...

example 2

[0052] Put in 1244kg of raw materials, including 350kg of PVCSG-4PVC resin; 450kg of 500-600 mesh heavy calcium carbonate (CaCO3); 200kg of algae earth; 60kg of 60-mesh straw powder or wood flour; 20kg of KSR organic rare earth composite stabilizer, 20kg of stearic acid; 12kg of polyethylene wax; 18kg of semi-refined paraffin; 33kg of copolymer ACR; 50kg of plasticizing and toughening agent of methyl methacrylate and acrylate copolymer; 20kg of PVC calcium-zinc composite stabilizer; 1.5kg of titanium dioxide color material and sapphire blue powder color material.

[0053] Since the water content of heavy calcium carbonate (CaCO3) is 2-8%, it can generally produce 1219.12-1144.48 kg of products.

[0054] The production method and technological process are the same as those mentioned above, so they are omitted.

example 3

[0056] Put in 1283kg of raw materials, including 350kg of PVCSG-5PVC resin; 350kg of 500-600 mesh heavy calcium carbonate (CaCO3); 150kg of algae earth; 100kg of 60-mesh straw powder or wood powder; 50kg of KGF organic calcium liquid composite stabilizer, 20kg of stearic acid; 20kg of polyethylene wax; 40kg of semi-refined paraffin; 70kg of ACR-like copolymer; 80kg of chlorinated polyethylene plasticizer and toughening agent; 25kg of PVC calcium-zinc composite stabilizer; 1kg of titanium dioxide color material, sapphire blue powder color material and pearl powder color material.

[0057] Since the water content of ground calcium carbonate (CaCO3) is 2-8%, the weight of the product is obtained after removing the water.

[0058] The production method and technological process are the same as those mentioned above, so they are omitted.
