This relates to a rust-preventing wax with improved splash resistance that is used to prevent rust from coming into contact with the outside air. [Conventional technology] Rust-preventing wax is applied to undercarriage parts such as blower shafts, steering devices, transmission devices, and brakes, which are installed in the underside of automobiles and under the floor, in order to prevent functional deterioration due to rust. It has been done. However, when cars are used in harsh conditions such as on rough roads or in cold regions, sand, gravel, ice and snow, water droplets, etc. are sprayed at high speed while driving, causing the anti-corrosion wax to wear out and peel off. Corrosive components such as water, sewage, and anti-freezing agents penetrate into these parts, causing problems such as rust and holes. For this reason, the performance of anti-rust wax is as follows:
Strong corrosion inhibition is required without causing wear or peeling under all driving conditions, and there is also a need for less stickiness, less adhesion of dust and mud, and no mating, discoloration, or significant swelling on painted surfaces. It is required that there be no adverse effects such as

。[Problems to be Solved by the Invention] Addition of resins, etc. has been used as a method to improve splash resistance, but drawbacks such as poor adhesion of the film at low temperatures and reduced rust prevention have not been resolved. Rust-preventive waxes are usually made of paraffin wax, microcrystalline wax, metal salts of petrolatum oxidized wax, metal sulfonate salts, etc. alone or in combination, and are mixed with rust-preventive additives as standard ingredients. In addition, lanolin, bitumen, resins, pigments, low pour point oils, etc. are added as appropriate, and products prepared with mineral spirits are usually used. [Means for Solving the Problems] In the present invention, in contrast to the standard components of the above-mentioned rust-preventing wax,
1 to 2 ethylene propylene copolymer or amorphous polypropylene alone or a mixture thereof
0% by weight, 10% by weight of polyisoprene, and 1 to 40% by weight of an inorganic filler to improve splash resistance. (Configuration) The present invention has the following features! al i. ) Ethylene brobylene copolymer (molecular weight 10,000 or less) Mouthwatering amorphous polypropylene (molecular weight too0 or less) 1 to 20% by weight (bl Polyisobrene (molecular weight 20,000 to 50,000) 1 to 10% by weight (C) This is a rust-preventing wax with improved splash resistance, which is characterized by containing 1 to 40% by weight of an inorganic filler as an essential additive to the conventionally used basic rust-preventing wax.Component of the present invention The following is a detailed explanation of ethylene brobylene copolymer.
8 Polypropylene ethylene brobylene copolymer is ethylene. It is a block copolymer of brobylene, which is an amorphous polymer.
Polypropylene having a molecular weight of 10,000 or less can be used.Amorphous polypropylene is an amorphous polypropylene that is a by-product during the production of crystalline (isotactic) polypropylene and can have a molecular weight of 10,000 or less. The proportion of ethylene brobylene copolymer and amorphous polypropylene in the rust-preventing wax composition is 1 to 20% by weight, either alone or as a mixture thereof. If it is less than 1% by weight, sufficient abrasion strength cannot be obtained, and if it exceeds 20% by weight, the viscosity of the composition becomes high, making spray application difficult.

生を防止する。Polyisoprene Polyisoprene that has hydroxyl groups and other functional groups in its molecular chain, and those that do not have functional groups can be used. The ratio of polyisoprene in the antirust wax composition is 1 to 10
Weight%. If the polyisoprene content is less than 1% by weight, desirable low-temperature adhesion cannot be obtained, and if it exceeds 10% by weight, the rust prevention properties are reduced. 1 Inorganic fillers include calcium carbonate, Myriki, talc,
Kaolin, etc. can be used. The proportion in the antirust wax composition is 1 to 40% by weight. If the amount of inorganic filler is less than 1%, no effect will be observed, and if it exceeds 40% by weight, the rust prevention properties will decrease and the film will become brittle. (Function) l) Ethylene brobylene copolymer, amorphous polypropylene, polyisoprene or ethylene brobylene copolymer Amorphous polypropylene, polyisoprene,
Even if a combination of inorganic fillers is added to a rust-preventive wax coating, it will not cause poor adhesion in the film at low temperatures or a decrease in rust prevention. 2) Even when external factors such as collisions with sand, ice and snow, and water droplets are applied to the anti-corrosion wax coating under harsh conditions, the ingredients in the coating maintain its toughness. A film is formed that prevents the rust-preventing wax from abrading, cracking, and peeling.

In No. 5, the peeling time was significantly inferior at 5 seconds, and other comparative samples also had inferior peeling times, and defects were observed in all items. (Effect) The anticorrosive wax with improved splash resistance according to the present invention can be made of ethylene brobylene copolymer, amorphous polypropylene alone or a mixture thereof, polyisoprene, and an inorganic filler. It is added to anti-chain wax, and by using it as an anti-corrosion wax for car bodies, it is possible to prevent wear and peeling caused by splashes.
