[0045] Preparation and performance test of anti-wet skid resin:

[0046] Softening point test: According to GB / T 2294-1997, use SYD-2806H automatic asphalt softening point tester for softening point test;

[0047] Infrared Spectrum: Infrared Test: According to GB / T 6040-2002, use Thermo Fisher IS5 Fourier Transform Infrared Spectrometer for testing.

Embodiment 1

[0049] In the 500ml flask that stirring device and thermometer are housed, be 25%: 10%: 65% ratio according to proportioning, successively add 75g C9 resin, 30g terpene resin and 195g α-methylstyrene resin, after heating and melting, Turn on the stirring, control the reaction temperature at 160±10°C, stir and mix for 1 hour, and discharge to obtain the anti-slip resin, the softening point of which is 98.8°C after testing.

[0050] The infrared spectrum of the prepared anti-wet skid resin is as follows figure 2 As shown, 2500-3200cm -1 Mainly -CH in the resin 3 ,-CH 2 Peak; 600-800cm -1 Mainly CH peak of substituted benzene ring in a-methylstyrene resin; 1430-1650cm -1 It is mainly the vibration peak of the benzene ring skeleton in a-methyl styrene resin; resins containing aromatic groups have a certain polarity, and can produce π-π conjugation effects with styrene-butadiene rubber and other rubbers containing benzene rings. Styrene has better compatibility.

[0055] In the 500ml flask that stirring device and thermometer are housed, according to proportioning is 25%: 10%: 65% ratio, successively add 75g coumarone resin, 30g modified terpene resin and 195ga-methylstyrene resin, heat After melting, turn on the stirring, control the reaction temperature at 160±10°C, stir and mix for 1 hour, and discharge to obtain the anti-slip resin composition, and the softening point is 115.3°C after testing.

[0056] Applications for preparing resins:

[0057] (1) Preparation of rubber composition

[0058] The resin prepared in the examples is used as an additive and added to the rubber for performance evaluation. The specific experimental formula is shown in the following table 2:

[0059] The formula of table 2 rubber composition

[0060]

[0061] According to the above formula, the rubber composition is obtained through two stages of master batching and final batching.

Abstract

The invention provides modified resin with wet-skid resistance as well as a preparation method and an application of the modified resin. The modified resin is prepared from the following components inpercentage by weight by a one-pot reaction: 1%-40% of petroleum resin, 1%-20% of modified natural resin and 40%-80% of pure monomer resin. The softening point for preparing the modified resin is 80-130 DEG C, a solvent is not needed in the preparation process of the modified resin, so that environmental pollution is reduced, and the raw materials are rich in resource and low in cost; meanwhile, by means of the one-pot reaction, the technical process is simplified, the technical cost is reduced, and the operation safety is improved; besides, the resin has good compatibility with rubber, and wet-skid resistance of the rubber can be improved substantially while other performance of the rubber is not affected.

Description

technical field [0001] The invention relates to the field of rubber industry additives, in particular to a modified resin with anti-wet skid performance, a preparation method and an application thereof. Background technique [0002] The anti-wet skid performance of automobile tires is an important guarantee for the safety of the car during driving, especially on wet and slippery roads in rainy days, the better the anti-wet skid performance of tires, the better the wet grip and the safer driving; The anti-wet skid performance is of great significance to the safety of automobiles. [0003] At present, there are some patents on improving the wet skid resistance of tire rubber at home and abroad, but there are also some deficiencies. For example, patent CN201610100151.3 discloses a rubber anti-slip resin and its preparation method. The anti-slip resin is made of the following raw materials in parts by weight: 70-90 parts by weight terpene resin, 5-20 parts by weight Cyclopente...
