Description

High-toughness anti-slip packaging material having heat shielding properties and construction method thereof

The present invention relates to a high toughness anti-slip packaging material having heat shielding properties and a method for constructing the same.

Methyl methacrylate (MMA, methyl methacrylate) pavement or waterproof paint is a paint that can be applied to concrete and steel structures. It has corrosion resistance, weather resistance and strong resistance to deterioration. In addition, it has the advantage of being able to install by hand, such as a pusher, roller, and mechanized spray application.

MMA paving material is a newly developed excellent waterproofing material or flooring material that realizes waterproof, corrosion resistance, and non-slip properties that can be designed in various patterns and designs in a single product because it is possible to express various colors beyond the black color of existing asphalt waterproofing materials or flooring materials. product. Although this MMA paving material is expensive, its use is expanding as a waterproofing treatment for bridge road surfaces that require high functionality and high durability, and as a protective material for concrete and steel structures of high-speed rail and light rail structures.

MMA resin does not discolor or fade even in heat or sunlight, has excellent mechanical properties, has high tensile performance and adhesive strength, and is a material that exhibits excellent workability at high and low temperatures.

By fixing aggregates and binders having a high coefficient of friction to the MMA resin on the road surface, it is possible to form a surface structure with excellent wear resistance and elasticity, so that an anti-slip pavement material can be formed on the road surface or the floor. This anti-slip pavement is usually applied to a thickness of 1 to 3 mm on sidewalks and bicycle roads, and is usually applied to a road of small cars with a thickness of 3 to 5 mm, and can be applied to a thickness of usually 5 to 10 mm for medium and large automobile roads.

Since this MMA resin passes most of the visible light and ultraviolet rays up to 270 nm, the heat island phenomenon caused by sunlight causes a serious problem in the durability of the MMA packaging material itself. An anti-slip packaging material and a construction method thereof have been proposed.

MMA anti-slip packaging materials with heat shielding properties developed so far adopt heat shielding pigments with high whiteness to have high sunlight reflectivity, so there is a problem of glare or optical illusions under sunlight. This phenomenon may appear more severe as the reflectance of the heat-shielding pigment is higher. Adding a colored pigment to the road pavement material can prevent or reduce this phenomenon in part, but there is a problem in that the heat shielding property is damaged and the cost increases due to the colored pigment, and above all, it is difficult to completely prevent this phenomenon.

Therefore, in the MMA anti-slip packaging materials having heat shielding properties, there is still a problem to solve these problems.

Comparative Examples 1-4

A non-slip flooring packaging material was prepared in the same manner as in Example 1, except that the amount indicated in Table 1 was used.

Test Example 1

The base surface was treated, and after drying the moisture to 4% or less, a primer was installed.

The high toughness anti-slip packaging material having heat shielding properties obtained in Examples 1 and 2 and the anti-slip packaging material obtained in Comparative Examples 1 to 4 were respectively coated on the primer to form an anti-slip coating film, and a roller was used to An anti-slip function was given, and the coating film was cured by drying completely.

The physical properties of the resulting MMA packaging material were measured according to the following test method, and the results are shown in Table 1. Evaluation results were expressed as excellent (◎), good (○), poor (Δ), and poor (×).

Test Methods:

(1) Heat shielding performance: Irradiated for a certain time at a distance of 30-50 cm from the UV lamp (250w), measured the temperature difference with the material surface, and evaluated as follows: ◎: Excellent (10°C or more), ○: Good ( 5~10℃), △: insufficient (5℃ or less), ×: poor (no temperature difference)

(2) Wear resistance: Measured according to SPS-KTS 1102-1890:2017 and evaluated as follows: ◎: Excellent (0.5% or less), ○: Good (1% or less), △: Poor (1% or more), × : Defective (more than 2%)

(3) Hardness: Measured according to SPS-KTS 1102-1890:2017, and the surface hardening state was evaluated in 4 stages: ◎: Excellent (complete curing: excellent), ○: Good (complete curing: average), △: Insufficient (partially cured), ×: Poor (non-cured)

(4) Workability: Anti-slip performance was evaluated during painting by adding a curing agent: ◎: Excellent, ○: Good, △: Poor, ×: Poor

Example 1 Example 2 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 MMA-based resin mixture 350 380 470.0 475.0 487.0 360.0 Highly reflective white heat shielding pigment 10 18 40 68 64 30 Highly reflective and highly pigmented colored heat-shielding pigment 10 10 - - - 10 Hollow Pigment 1 10 18 45 46 85 30 Inorganic pigment (general pigment 1) 20 18 50 18 17 34 Inorganic pigment (general pigment 2) - - 15 13 13 - aggregate 420 386 270 270 250 450 calcium carbonate 150 200 110 110 84 86 total amount 1000 1000 1000 1000 1000 1000 heat shielding performance ◎ ◎ △ △ △ ◎ wear resistance ◎ ◎ ◎ ◎ ◎ ◎ hardenability ◎ ◎ ◎ ◎ ◎ ◎ Workability ◎ ○ △ △ × △

As can be seen in Table 1, Examples 1 to 2 and Comparative Examples 1 to 4 were all excellent in abrasion resistance because the MMA resin used a hard-type MMA resin and a soft-type MMA resin together.

On the other hand, comparing the heat shielding properties, Examples 1 and 2 mixed use of a high reflective white heat shielding pigment and a high reflectivity and high coloring power colored heat shielding pigment, and using a hollow pigment in an appropriate amount, compared to Comparative Examples 1 to 4, the heat shielding pigment Although the total amount used is small, it was confirmed that superior heat shielding properties and workability could be achieved compared to Comparative Examples 1-4. On the other hand, in Comparative Examples 1 to 4, the heat shielding pigment and the hollow pigment were used in excess than in Examples 1 to 2, but compared to Examples 1 and 2, the heat shielding performance was rather insufficient, and thus workability was lowered.

In addition, Examples 1 to 2, compared to Comparative Examples 1 to 4, use a small amount of additives such as a heat-shielding pigment, a hollow pigment and an inorganic pigment, and even when aggregates and calcium carbonate are added in larger amounts, better physical properties and operation In addition to obtaining good performance, an economic advantage of using a smaller amount of MMA resin can be obtained.

Comparative Examples 5 to 7

Similar to Example 1, except that the MMA-based resin mixture contains the hard-type MMA resin and the soft-type MMA resin in the ratios shown in Table 2 (ratios other than the range of 80:20 to 60:40) In the process, a high-tear non-slip packaging material having heat shielding properties was prepared.

Test Example 2

Although the same as in Test Example 1, an anti-slip coating film was formed using the high-tear non-slip packaging material having heat shielding properties obtained in Example 1 and Comparative Examples 5 to 7. Here, an anti-slip function was provided using a roller, and the coating film was cured by drying completely.

The test method and evaluation method were the same as in Test Example 1.

Comparative Example 5 Example 1 Comparative Example 6 Comparative Example 7 Hard-Type MMA Resin 90 70 40 30 Soft-Type MMA Resin 10 30 60 70 The tensile strength ◎ ○ △ △ (MPa) 12 10 4 3 elongation △ ○ ◎ ◎ (%) 17 49 570 610

According to Table 2, when the ratio of the hard-type MMA resin is high (Comparative Example 5), the tensile strength is excellent but the elongation is lowered, and when the ratio of the hard-type MMA resin is low (Comparative Examples 6 and 7), It can be seen that the elongation is excellent, but the tensile strength is lowered.

On the other hand, when the ratio of the hard-type MMA resin is appropriate (Example 1), both elongation and tensile strength are good, so it can be seen that the balance (balance) of physical properties is excellent.
