Description

Safe and environment-friendly anti-skid composition and application thereof in vehicles

Technical Field

The invention relates to the field of antiskid of vehicles, in particular to a safe and environment-friendly antiskid composition and application thereof in vehicles.

Background

Along with the development of science and technology and the progress of times, the frequency of using vehicles in daily life of people is higher and higher, so that the requirements on the appearance, performance, comfort, safety and the like of the vehicles are higher and higher, on one hand, the ground where the vehicles are located needs to be subjected to anti-skid treatment, the friction force between the vehicles and the ground is increased, and traffic accidents caused by over-skid are prevented; vehicle interior floors, on the other hand, are no exception. Due to the particularity of the vehicle, the interior decoration ground needs to be light, occupies small space, and has multiple effects of pollution resistance, skid resistance, sound insulation and the like. At present synthetic material floors, such as stone plastic floors, rubber floors, floor coverings and the like are commonly used in vehicles. Wherein, the stone plastic floor and the plastic floor are easy to wear, crack and pollute and have short service life. The rubber floor has large taste, and scars can be left after the rubber floor is corroded to influence the appearance of the floor; because the surface of the rubber floor is of a soft cotton structure, the surface is difficult to repair after being damaged; after the rubber floor meets water, bubbling or edge warping can easily occur.

At present, the anti-skid measures of the ground (floor) are mainly divided into two types, one type adopts corrosive liquid to treat the floor, the ground is made into a structure with macroscopic or microscopic concavo-convex unevenness, and the friction coefficient is improved by utilizing the suction cup effect generated by the structure under pressure. However, the current anti-slip compositions on the market generally have the disadvantage of poor penetration. Another type of surface is coated with an anti-slip composition that increases the coefficient of friction by adhering to the surface. Although the method of applying the anti-slip composition to the surface of the floor is practical and has an excellent anti-slip effect, the applied anti-slip layer is gradually worn away with the lapse of time, thereby losing the anti-slip effect.

Polyethylene wax and acrylic emulsion as main film forming bodies have excellent film forming property and light and weather resistance, but have the defects of poor binding force, poor hardness, insufficient wear resistance and the like, so that the application range is limited. In addition, the anti-slip composition has poor binding force with the ground, and the anti-slip composition is gradually damaged along with the time migration, so that the anti-slip function is lost.

The oxidized polyethylene wax is a modified wax product containing partial polar groups (such as carboxyl and hydroxyl). The polishing agent has the original polishability, self-repairing property and scratch resistance of paraffin and polyethylene wax, and is non-toxic, non-corrosive and stable in chemical performance. When in use, the coating does not need to be heated and melted or dissolved by an organic solvent, has uniform film formation, good coverage and water-proof and anti-skid commonality.

The preparation method of the oxidized polyethylene wax emulsion at least comprises the following steps:

(1) 30g of oxidized polyethylene wax and 6-10 g of emulsifier are weighed and added into a three-neck flask. The three-neck flask is placed in a constant-temperature oil bath to be heated.

The oxidized polyethylene wax emulsion reduces the average particle size of the emulsion by adding the alkaline additive and the low-carbon alcohol, and the particle size distribution is more concentrated and the emulsion is more stable.

Acrylic emulsion

The acrylic emulsion is one of main film forming substances, and has excellent film forming protection effect and high glossiness.

The preparation method of the silicone-acrylate emulsion comprises a pre-emulsification full-continuous method, a one-time feeding method, an initiator dropping method and a monomer dropping method. The pre-emulsification full-continuous method comprises the following steps: adding water, an emulsifier, a mixed monomer of an acrylic monomer and organosilicon into a homogenizer, and homogenizing at 25-30 ℃ for 0.5-1.0 h to obtain a pre-emulsion; then continuously dropwise adding the pre-emulsion and an initiator into the reactor to finally generate a copolymer emulsion. The one-time feeding method comprises the steps of adding water, an emulsifier and a mixed monomer into a reactor at one time, fully emulsifying, raising the temperature to the reaction temperature, adding an initiator at one time, and carrying out polymerization reaction at a constant temperature. The initiator dropping method is characterized in that an initiator solution is added into a reactor at a constant speed on the basis of a one-time feeding method, and the temperature of the system is kept constant in the reaction process. The monomer dropping method is to put all water into a reactor, then drop the mixed monomer, the initiator and the emulsifier at the reaction temperature for reaction, and cool down after the polymerization reaction is finished, thus obtaining the copolymer emulsion.

Applicants have discovered that the addition of a coalescent is effective to lower the minimum film forming temperature of the polymer emulsion, allowing the polymer particles to dissolve and fuse into a continuous film layer.

Dispersing agent

In a preferred embodiment, the dispersant is at least one selected from the group consisting of a polycarboxylate type dispersant, a polyacrylate dispersant, and a polymer type dispersant.

As a preferred embodiment, the dispersant is selected from polycarboxylate type dispersants.

wherein GY-D900, GY-D180, GY-D09, GY-D05, GY-D800, GY-D06 and GY-D07 are purchased from Beijing Guangyuan Yinong Chemicals, Inc.; SN-5040, SN-5027 were purchased from Noop, Japan.

Leveling agent

As a preferred embodiment, the leveling agent is a hydroxy polyacrylate.

In the present application, the polyacrylates improve flow and leveling, providing a smooth, slippery and satisfactory antislip composition. In addition, the anti-skid composite can provide leveling property and simultaneously play a role in wetting, and cannot influence the binding force of the anti-skid composite and a floor and pollute the environment. However, pure acrylates are not very good leveling because they are limited by compatibility with the polymer solution.

The anti-skid composition of the application is added with the hydroxyl polyacrylate and has certain compatibility with polymer emulsion. Meanwhile, due to the polarity of hydroxyl, water vapor can be effectively taken away in the process of migrating to the surface of the anti-slip composition, the formation of shrinkage cavities is eliminated, a better surface effect is realized, and meanwhile, the gloss can be increased.

The preparation method of the hydroxyl polyacrylate at least comprises the following steps:

(1) adding toluene as a solvent into a three-neck flask, and heating at the rotating speed of 1000 rpm;

(2) adding 30g of ethyl acrylate, 10g of butyl acrylate and a certain amount of hydroxyethyl acrylate into a beaker, and adding 0.3-0.5 g of initiator dibenzoyl peroxide for dissolving and shaking up;

(3) when the temperature of the toluene in the three-neck flask rises to be higher than 100 ℃, dropwise adding the mixture obtained in the step (2) into the three-neck flask, finishing dropwise adding within 2h, and then continuously reacting for 1-3 h; then adding a small amount of initiator, continuing the reaction for 2 hours, and then distilling the solvent under reduced pressure to obtain the catalyst.

Wherein, in the step (2), the hydroxyethyl acrylate accounts for 5-80 g.

In a preferred embodiment, the hydroxyl value of the hydroxyl polyacrylate is 40 to 150mgKOH g^-1。

In the application, the hydroxyl value of the hydroxyl polyacrylate is tested according to GB/T12008.3-2009 standard.

The Applicant has found that the hydroxyl value of the hydroxyl polyacrylates varies and has a great influence on the surface effect of the antislip composition. The possible reason is that when the hydroxyl value of the hydroxyl polyacrylate is greater than 150mgKOH g^-1When the anti-skid composition is used, the compatibility of the hydroxy acrylic acid and the anti-skid composition system is too good, the surface energy difference formed by the hydroxy polyacrylate is not enough, the hydroxy acrylic acid is easy to untie, no power is transferred to the interface of the anti-skid composition, and the required flow control effect is lost; when the hydroxyl value of the hydroxyl polyacrylate is less than 40mgKOH g^-1In the process, the compatibility of the hydroxyl polyacrylate and the antiskid composition system is poor, the alkyl chain in the hydroxyl polyacrylate shields the antiskid composition, and the leveling is interrupted.

Preferably, the hydroxyl value of the hydroxyl polyacrylate is 90 mgKOH-g^-1。

As an embodiment, the defoaming agent is selected from at least one of polyether modified silicone, polysiloxane-polyether copolymer, polyethylene glycol-polysiloxane mixture.

In the present application, the antifoaming agent (model: TCB-1)) was purchased from south China sea field chemical Co., Ltd.

As a preferred embodiment, the anti-slip composition component further comprises 10 to 30 parts by weight of a filler; wherein, the filler is at least one of silicon dioxide, alumina, titanium dioxide and calcium carbonate.

As a preferred embodiment, the filler is a hydroxy fatty acid modified filler.

In the application, the oxidized polyethylene wax emulsion and the acrylic emulsion have excellent film forming property as main film forming bodies, but have the defects of poor bonding force with the ground, insufficient wear resistance and the like. By adding a filler, the wear resistance of the anti-slip composition can be improved. But the compatibility of the filler and the polymer emulsion is poor, so that the antiskid composition system is unstable, and after the hydroxy fatty acid modified filler is added, on one hand, the hydroxy groups on the fatty acid can interact with polar groups in the polymer emulsion, so that the dispersibility of the filler in the polymer emulsion is improved; meanwhile, the hydroxy fatty acid modified filler and the polymer emulsion form a crosslinking system, the molecular weight of the whole crosslinking system is larger, and stronger acting force is generated with the ground, so that the bonding force with the ground is enhanced. The applicant has found that, surprisingly, the films formed on the ground by adding the hydroxy fatty acid modified filler are smoother, smoother and more uniform than the films formed on the ground by adding the non-modified filler in the non-slip composition, and have a certain hydrophobic effect. The possible reasons are: in the process of coating the anti-slip agent on the ground, the long chain of the hydroxy fatty acid on the modified filler has fluidity, and a flat and smooth film can be formed on the ground. After the coating is finished and a solid film is formed, on one hand, long chains of hydroxy fatty acid are mutually wound to form a first cross-linking point; on the other hand, active groups such as hydroxyl, carboxyl and the like in the solid film interact with each other to increase the crosslinking density, a continuous crosslinking network structure is formed among molecules to form a second crosslinking point, and the two crosslinking points interact with each other to prevent water molecules from damaging the crosslinking degree of the film.

Preferably, the hydroxy fatty acid is at least one selected from the group consisting of 9, 10-dihydroxyoctadecanoic acid, 3, 11-dihydroxyhexadecanoic acid, 2, 3-trihydroxyoctadecanoic acid, and 8,9, 13-trihydroxybehenic acid.

The applicant found that when the hydroxyl fatty acid chain is short, the formed slip-resistant film is not flat; when the hydroxyl fatty acid chain is long, the fatty acid chain can be tangled during the coating process of the anti-slip agent, and the smoothness of the anti-slip film can also be affected.

In one embodiment, the hydroxy fatty acid modified filler is prepared by the steps of:

(1) adding 1g of filler into a solvent, and performing ultrasonic treatment;

(2) heating the mixture in the step (1) to 80 ℃, and stirring at a speed of 400rpm while condensing and refluxing. And then adding 0.01-0.5 g of hydroxy fatty acid, continuously heating for 4-24 h, and filtering to obtain the product.

Wherein, the solvent in the step (1) is not particularly limited, and the filler can be dispersed and the hydroxy fatty acid can be dissolved. Mention may be made, among others, of: at least one of alcohols, ketones and ethers.

As a preferred embodiment, the total weight of the leveling agent and the filler is 10-35 parts.

Preferably, the total weight of the leveling agent and the filler is 15-25 parts.

The applicant finds that the anti-skid composition contains active groups such as hydroxyl groups and the like to improve the toughness and the flatness of the anti-skid film, but when the hydroxyl group content is higher, the hydrophilicity of the anti-skid film is increased, and a large amount of water molecules can damage the crosslinking degree of the anti-skid film, so that the anti-skid film is swelled.

The second aspect of the present invention provides a preparation method of the safe and environment-friendly anti-slip composition, comprising the steps of:

A third aspect of the invention provides the use of the anti-slip composition for use in a vehicle.

As a preferred embodiment, the anti-slip composition is used for vehicle interior trim flooring.

In the present application, the vehicle is not particularly limited, and there may be exemplified: high-speed rail, train, subway, bus, airplane, ship, yacht, pleasure boat, tram, trolley bus, automobile, etc.

As a preferred embodiment, the anti-slip composition may also be used on the ground, track, etc. on which the vehicle is traveling.

The present invention will be specifically described below by way of examples. It should be noted that the following examples are only for illustrating the present invention and should not be construed as limiting the scope of the present invention, and that the insubstantial modifications and adaptations of the present invention by those skilled in the art based on the above disclosure are still within the scope of the present invention.
