Technical Field
The invention relates to the technical field of rubber and plastic heat-insulation boards, in particular to a low-odor rubber and plastic heat-insulation board for automobile decoration.
Background
The existing automobile materials are mostly CR and polyurethane sponge and foamed polyethylene, a single material is difficult to meet the effects of heat preservation, sound insulation and decoration, an adhesive composite mode is often adopted, the tear strength is poor, the process cost is increased, the problems that the water absorption rate and the dust absorption are increased due to the open-cell semi-open structure and the like are solved, and the long-term use experience is poor.
Therefore, we propose a low-odor rubber-plastic insulation board for automobile decoration to solve the above problems.
Disclosure of Invention
The invention aims to solve the defects in the prior art, and the low-odor rubber and plastic heat-insulation board for automobile decoration uses excellent heat-insulation and sound-insulation performance of rubber and plastic to replace a composite material, so that the use cost is reduced, and the problem of unstable long-term use performance is solved.
The low-odor rubber-plastic heat-insulation board for automobile decoration contains: 11.32-11.34% of nitrile rubber, 1.2-1.4% of butadiene rubber, 20.88-20.90% of talcum powder, 12.93-12.95% of aluminum hydroxide, 14.88-14.90% of polyvinyl chloride, 1.93-1.95% of carbon black, 20.70-20.72% of chlorinated paraffin, 1.2-1.4% of dispersing agent and 4-6% of deodorant.
The invention has the beneficial effects that:
a plurality of deodorant components are added into a raw material system to replace unnecessary products which generate pungent odor in the raw materials, and simultaneously, the odor is removed by physical methods such as baking and the like, so that the volatile odor of the rubber and plastic product reaches the level of 3.0 required by the automobile industry.

b. respectively mixing a plasticizer, a foaming agent, nitrile rubber and a nucleating agent, and banburying, milling and rolling into a foaming agent film which is a No. 2 material;
c. respectively weighing an activating agent, an accelerator, nitrile rubber, a plasticizer and a nucleating agent, and carrying out closed milling and rolling to obtain a vulcanization accelerator rubber sheet as a material No. 3;
d. respectively weighing materials No. 1, No. 2 and No. 3 according to the required weight of the formula, uniformly mixing and rolling in an open mill, and cutting into rubber strips with certain specifications;
s2, extrusion: feeding the materials into an extruder, flattening, integrating and re-extruding the materials through a multi-roll calender, and controlling the extrusion temperature, pressure and rotating speed;
s3, vulcanization foaming: continuously feeding the extruded and shaped film to be foamed into a foaming furnace for foaming, and adjusting the material rod transmission rate in the foaming furnace and the temperature of each area to enable the film to be vulcanized and foamed according to preset requirements;
s4, traction cooling: cooling the product formed by foaming in the foaming furnace by air cooling to solidify the structure;
s5, post-processing: the produced rubber and plastic product is baked in a 80 ℃ oven to continuously remove volatile gas, and is taken out after two hours and cooled, and the process is repeated for 4 to 5 times.
