preparation example Construction

[0049] A kind of preparation method of the tread rubber of a kind of novel self-contained pattern of the present application, comprises the steps:

[0050] The first step, the preparation of the anti-wet skid foam rubber unit A, controls the rotor speed of the internal mixer to 40-80RPM, the temperature is 130-150°C, and the pressure of the top bolt is 30-50N / CM2. The specific process includes the following steps:

[0051] (1) Add foam rubber to press the top bolt, and keep masticating in the internal mixer for 120-180 seconds;

[0052] (2) Add materials other than accelerant, sulfur and foaming agent to the top bolt, and press the top bolt for 120-180 seconds;

[0053] (3) After air-cooling the prepared mixed rubber for 1-2 hours, add accelerator NOBS and accelerator DTDM to the open mill. The temperature of the open mill is required to be 55-75°C, and practice 8-15 times.

[0054] (4) After air-cooling the prepared mixed rubber for 2-4 hours, add sulfur and foaming agent to...

Embodiment 1

[0066]Embodiment 1, as shown in the figure, a new type of tread rubber with its own pattern, including anti-wet skid foam rubber unit A, high wear-resistant rubber unit B and tear-resistant rubber unit C, the anti-wet skid foam rubber unit The foam rubber unit A and the high wear-resistant rubber unit B are complementary, and the tear-resistant rubber unit C is located at the bottom of the anti-wet skid foam rubber unit A and the high wear-resistant rubber unit B, and the anti-wet skid foam rubber unit A Embedded in the high wear-resistant rubber unit B to form a pattern, the pattern formed by the anti-wet skid foam rubber unit A includes a mirror-symmetrical first pattern structure A-1 and a second pattern structure A-2, the first The pattern structure A-1 includes a rib pattern structure A-11 and a bionic pattern structure A-12, the strip pattern structure A-11 and the bionic pattern structure A-12 are separated by the main groove E, and the strip pattern structure A-11 and ...

Embodiment 2

[0093] Embodiment 2. The difference between this embodiment and Embodiment 1 is that the distance k3 between the central groove D and the main grooves E on both sides is equal to 150 mm; the width k2 of the main groove E is the same as that of the central groove D The width k1 is the same, which is 15mm; the radius r1 of the central circular node A-111 is 8mm, and the radius r2 of the side circular node A-112 is 4.5mm; the width f of the auxiliary groove F is 9mm central circular The length t1 of the auxiliary groove F between the node A-111 and the side circular node A-112 is 22mm;

[0094] The auxiliary grooves F located on the same side of the central circular node A-111 are parallel to each other, and the distance l between two adjacent auxiliary grooves F located on the same side of the central circular node A-111 is equal to 45mm; The length t2 is 90 mm; the included angle γ between the auxiliary groove F and the main groove E is 45 degrees.

[0095] The auxiliary groov...

Abstract

The invention relates to the technical field of automobile tires, in particular to novel tread rubber with a pattern. The novel tread rubber comprises a wet-skid-resistant foaming rubber unit, a highly wear-resistant rubber unit and a tearing-resistant rubber unit; the wet-skid-resistant foaming rubber unit and the highly wear-resistant rubber unit are complementary; the tearing-resistant rubber unit is positioned at the bottoms of the wet-skid-resistant foaming rubber unit and the highly wear-resistant rubber unit; the wet-skid-resistant foaming rubber unit is embedded into the highly wear-resistant rubber unit to form the patterns; the pattern formed by the wet-skid-resistant foaming rubber unit comprises a first pattern structure and a second pattern structure which are in mirror symmetry; the first pattern structure comprises a striped pattern structure and a bionic pattern structure; and the striped pattern structure and the bionic pattern structure are separated by a main groove.The novel tread rubber is convenient to manufacture, has ultra-high wet skid resistance, and ensures good wear resistance, rolling resistance, other physical and mechanical properties and the like, and the driving safety of automobiles can be improved greatly.

Description

technical field [0001] The invention relates to the technical field of automobile tires, in particular to a novel tread rubber with a pattern and a preparation method thereof. Background technique [0002] Tires are an important component of automobiles and the most important product of the rubber industry. The wet skid resistance of the tire is the main performance of the tire tread rubber, and its quality is the main factor to ensure the safety of the car, especially in rainy and snowy weather. However, the wet skid resistance is often opposed to the wear resistance of the tread rubber. While improving the wet skid resistance of the tire, the wear resistance often decreases. This is the focus and difficulty for researchers to study. It is of great significance to improve the wet skid resistance of the tread rubber while ensuring the wear resistance to protect the safety of people's lives and property. Contents of the invention [0003] The purpose of the present inven...
