The present invention relates to an anti-slip member, and more particularly to an anti-slip member for stairs, handrails, floors, etc., using a specific ethylene/α-olefin copolymer. Various members with anti-slip functions have been known, but most of them are made of polyvinyl chloride resin (hereinafter referred to as PVC), ethylene-vinyl acetate copolymer (hereinafter referred to as EVA), and rubber. Among these, especially soft
PVC is the most commonly used. However, soft PVC contains a large amount of plasticizer, and as a result of long-term use, the plasticizer migrates, resulting in deterioration of the surface feeling and lack of flexibility, resulting in brittleness.These tendencies are particularly pronounced at low temperatures, making it difficult to put into practical use. becomes difficult. Another disadvantage of PVC is that it generates hydrogen chloride when incinerated. The properties of EVA change depending on the vinyl acetate content contained in it, but anti-slip materials require flexibility, so those with a relatively high vinyl acetate content are used. Copolymers have a strong acetic acid odor, which impairs workability during molding. Furthermore, it is hygroscopic and susceptible to hydrolysis when exposed to high temperatures, so it does not have sufficient weather resistance. Rubber is not preferred in terms of energy saving because it requires complicated steps such as addition of various processing aids and vulcanization during mastication. The present invention solves the drawbacks of the above-mentioned resins, etc., and also has an ethylene/α-olefin copolymer that is lightweight, has excellent weather resistance, thermal stability, heat resistance, processability, and does not require crosslinking. The object of the present invention is to provide an anti-slip member made of an integrated structure. That is, the present invention provides the following (a) obtained by copolymerizing ethylene and α-olefin in the presence of a catalyst consisting of a solid catalyst component containing at least magnesium and titanium and an organoaluminum compound.
The present invention relates to an anti-slip member made of an ethylene/α-olefin copolymer having the properties described in (d). (a) Melt index is 0.01 to 100g/10min,
Preferably 0.1-50g/10min, (b) Density 0.860-0.910g/cm 3 , preferably 0.880
~0.900 g/cm 3 , (c) The temperature (Tm) of the maximum peak in differential scanning calorimetry (DSC) is 100°C or higher, preferably 110°C or higher, (d) Boiling n-hexane insoluble matter is 10% by weight % or more, preferably 30-85% by weight. The ethylene/α-olefin copolymer used in the present invention must satisfy all of the above conditions (a) to (d). [Condition a] Melt index (JIS K6760) of (a) is 0.01
If it is less than 10g/10min, the workability will be poor and the
If it exceeds g/10 min, the surface of the molded product becomes sticky and the mechanical strength decreases, which is not preferable. [Condition b] If the density (JIS K 6760) of (b) is less than 0.860 g/cm 3 , the melting point will be lowered, so it cannot be used at high temperatures, and the mechanical strength etc. will also be poor, which is not preferable. [Condition c] The maximum peak temperature (Tm) of DSC in (c) is a value that correlates with the crystal morphology. If Tm is less than 100℃, the heat resistance and surface strength of the anti-slip member will be insufficient, and the molded product will be damaged. When used at high temperatures, plastic deformation tends to occur, which is undesirable. [Condition d] Next, the boiling n-hexane insoluble content is a guideline for the proportion of amorphous parts and the content of low molecular weight components, and when the insoluble content is less than 10% by weight, This results in problems such as poor performance due to decreased strength and a sticky surface, which makes it easier for dirt to adhere.
It becomes difficult to maintain the shape of the anti-slip member itself. The method for measuring the boiling n-hexane insoluble matter and DSC in the present invention is as follows. [Measurement method for boiling n-hexane insoluble matter] A sheet with a thickness of 200 μm was formed using a heat press, and three sheets of 20 mm x 30 mm in length and width were cut from the sheet, and the sheets were placed in a double-tube Sotsukurray extractor. Extraction is carried out using boiling n-hexane for 5 hours. After taking out the n-hexane insoluble matter and vacuum drying (7 hours under vacuum, 50° C.), the boiling n-hexane insoluble matter is calculated using the following formula. Boiling n-hexane insoluble content (weight %) = Extracted sheet weight / unextracted sheet weight x 100 (weight %) [Measurement method by DSC] Precisely weigh approximately 5 mg of sample from a 100 μm thick hot press-molded film. The sample was set in a DSC device, heated to 170°C, held at that temperature for 15 minutes, and then cooled to 0°C at a cooling rate of 2.5°C/min.
Next, from this state, increase the temperature to 170°C at a rate of 10°C/min.
Measurement is performed by raising the temperature to . The temperature at the peak position of the maximum peak that appeared during the temperature increase from 0°C to 170°C is defined as Tm. The ethylene/α-olefin copolymer of the present invention can exhibit desired performance by satisfying all of the above-mentioned properties. The α-olefin copolymerized with ethylene has 3 to 12 carbon atoms. Specifically, propylene,
Butene-1, 4-methylpentene-1, hexene-1, octene-1, decene-1, dodecene-1
etc. can be mentioned. Particularly preferred among these are propylene and butene-1. The α-olefin content in the ethylene-α-olefin copolymer is preferably 5 to 40 mol%. Below, ethylene used in the present invention and α-

The amount of organoaluminum compound used is not particularly limited, but is usually 0.1 to 1000% of the titanium compound.
Molar times can be used. In addition, by bringing the above-mentioned catalyst system into contact with an α-olefin and then using it in the polymerization reaction, the polymerization activity can be greatly improved, and the system can be operated more stably than when untreated.

Examples of these α-olefins include propylene, butene-
Examples include 1, pentene-1, 4-methylpentene-1, hexene-1, octene-1, decene-1, dodecene-1, and mixtures thereof. The temperature and time during contact between the catalyst system and the α-olefin can be selected within a wide range, for example, the contact treatment can be carried out at 0 to 200°C, preferably 0 to 110°C, for 1 minute to 24 hours. α to contact

It is desirable to treat 1 g of the solid catalyst component with 1 g to 50,000 g, preferably 5 g to 30,000 g of α-olefin, and react with 1 g to 500 g of α-olefin per 1 g of the solid catalyst component. At this time, the pressure at the time of contact can be arbitrarily selected, but it is usually desirable to contact under a pressure of -1 to 100 kg/cm 2 ·G. During the α-olefin treatment, the entire amount of the organoaluminum compound used may be combined with the solid catalyst component and then brought into contact with the α-olefin, or a part of the organoaluminum compound used may be combined with the solid catalyst component. After combining with α
- The polymerization reaction may be carried out by contacting with the olefin and adding the remaining organoaluminum compound separately during the polymerization. Furthermore, there is no problem even if hydrogen gas coexists during contact between the catalyst system and α-olefin.
Further, there is no problem even if other inert gases such as nitrogen, argon, and helium coexist. The polymerization reaction is carried out in the same manner as the polymerization reaction of olefins using ordinary Ziegler type catalysts. That is, all reactions are carried out in a gas phase, in the presence of an inert solvent, or in the presence of the monomer itself as a solvent, substantially free of oxygen and other substances. The polymerization conditions for olefin are temperatures of 20 to 300℃, preferably 40 to 200℃.
℃, and the pressure is normal pressure to 70 kg/cm 2 ·G, preferably 2 kg/cm 2 ·G to 60 kg/cm 2 ·G.
Although the molecular weight can be controlled to some extent by changing polymerization conditions such as polymerization temperature and catalyst molar ratio, it is effectively carried out by adding hydrogen to the polymerization system. Of course, a two-stage or more multi-stage polymerization reaction with different polymerization conditions such as hydrogen concentration and polymerization temperature can be carried out without any problem. As described above, specific ethylene and - It was completely unexpected and surprising that an anti-slip member with excellent properties could be provided using an olefin copolymer. The ethylene/α-olefin copolymer of the present invention is clearly distinguished from the ethylene/α-olefin copolymer obtained by using one containing vanadium as a solid catalyst component. Even if the monomers constituting the copolymer are the same and the density is the same, DSC
The copolymer of the present invention has a higher Tm than that of the copolymer of the present invention, and the insoluble matter in boiling n-hexane is 10% by weight or more in the copolymer of the present invention, whereas the latter has no insoluble matter or even if it exists, The amount is extremely small. Due to these differences in the copolymers themselves, when used as the anti-slip member of the present invention, the copolymers of the present invention have superior heat resistance and strength as well as superior strength compared to the latter. , has an excellent balance of various performances required for use as anti-slip members. Furthermore, unlike titanium, vanadium present in the copolymer as a desolvent residue poses a toxicity problem, so a catalyst removal step is essential.However, when titanium is used as in the present invention, the toxicity of the catalyst residue No problems arise and the copolymers of the present invention, which use a highly active catalyst in combination with a magnesium support, are extremely economical since no catalyst removal step is required. Although the copolymer of the present invention may be used after being molded without adding a filler, it is preferably used as a composition containing an inorganic and/or organic filler. Inorganic and/or organic fillers include calcium carbonate, aluminum hydroxide, magnesia, talc, clay, titania, carbon black, fine silica, glass fiber, phenolic resin, petroleum resin, synthetic fiber (polyamide), and the like. Known methods can be used to blend the copolymer of the present invention and filler. At this time, as well as ordinary polyolefins, various stabilizers, foaming agents, foaming aids,
Flame retardants, pigments, etc. may also be added. Further, the molded product may be subjected to secondary processing such as embossing. The means, handrails, etc. to which the anti-slip member of the present invention is applied have a large anti-slip effect due to its large coefficient of friction, and the surface can be processed with irregularities, etc., and has an extremely low density, so it is lightweight and easy to construct. It is easy to mold, does not require any steps such as vulcanization and crosslinking after molding, and is extremely economical. In addition, as is clear from the basic structure of the resin, it does not contain unsaturated bonds and does not contain low molecular weight so-called wax components, so it has excellent weather resistance and can be used not only outdoors but also on outdoor stairs.
It can be used for handrails, steps of large mechanical equipment, ramps, etc. without any problems. Since the copolymer of the present invention contains a moderate amount of crystalline portion, it has elasticity not found in other conventional resins or rubbers, and after application, it has cushioning properties and excellent surface feeling. . When compared to rubber, the anti-slip member using the specific ethylene/α-olefin copolymer of the present invention does not require complicated processing steps and has excellent performance such as being able to be colored freely. The present invention will be specifically explained below with reference to Examples, but the present invention is not limited thereto.
