Embodiment 1

[0055] A process for dipping bitumen, which is used for dipping bitumen on a base cloth to make a waterproof membrane with tires, comprising the following steps:

[0056] S1. Pre-impregnation: apply asphalt to the surface of the base fabric or dip the base fabric into asphalt so that the asphalt covers the surface of the base fabric, and then apply the asphalt-coated base in a direction at an acute angle to the vertical direction cloth for extrusion;

[0057] S2. Drying: drying the prepreg tire base treated in step S1 by contacting the rolling heating element;

[0058] S3. Coating: apply asphalt on the surface of the prepreg base treated in step S2 or dip the prepreg base into asphalt so that the asphalt covers the surface of the prepreg base, and then use a high-speed rolling heating element for rough pressing and reuse Roll the heating element at low speed for fine pressing.

[0059] Such as figure 1 As shown, step S1 abandons the method of extruding the tire base fabric ...

Embodiment 2

[0062] Such as image 3 As shown, a system for dipping asphalt includes a prepreg device 100 , a drying device 200 and a coating device 300 arranged in sequence.

[0063] The prepreg device 100 includes a prepreg tank 110 for holding asphalt and dipping the base fabric with asphalt, and an extrusion mechanism arranged above the prepreg tank 110 to squeeze the base fabric dipped in asphalt 120.

[0064] The extruding mechanism 120 includes at least two extruding rollers 121, the rotation axes of the adjacent two extruding rollers 121 are parallel to each other but not in the same vertical plane, and the tire base fabric is dipped in the prepreg tank 110 after being dipped with asphalt from the corresponding The lower sides of the two adjacent squeeze rollers 121 penetrate into the gap between the two adjacent squeeze rollers 121 . Such as Figure 5 As shown, two adjacent extrusion rollers 121 form an extrusion action on the tire base fabric passing through them, and the plac...

Embodiment 3

[0076] The difference between this embodiment and embodiment 2 is that, as Figure 11 As shown, it also includes a coating roller 131 arranged on one side of the extrusion mechanism 120 and at least partly protruding into the prepreg tank 110 to contact the asphalt. Dip the device and leave the prepreg device after passing through the coating roller 131 and the extrusion mechanism 120 in sequence. During the rotation of the coating roller 131, the asphalt in the prepreg tank 110 is brought up and coated on the subgrade passing through the coating roller 131 Cloth the lower surface. In this solution, the tire base cloth does not need to enter the asphalt in the prepreg tank 110, just cross the coating roller 131 and keep in effective contact with the coating roller 131 during this process. The lower surface of the cloth will be covered with asphalt, which will eventually form a traditional half-tire waterproofing membrane. Preferably, the surface of the coating roller 131 is ...

Abstract

The invention relates to the technical field of asphalt waterproof coiled material production equipment, and discloses an asphalt dip-coating process and system, which are used for dip-coating asphalton tire base cloth to manufacture a waterproof coiled material with a tire. The process comprises the steps of: pre-soaking: smearing the asphalt on the surface of the tire base cloth or immersing the tire base cloth into the asphalt to enable the surface of the tire base cloth to be covered with the asphalt, extruding the tire base cloth covered with the asphalt on the surface in a direction forming an acute angle with the vertical direction; drying: drying the pre-impregnated tire base in a manner of being in contact with a rolling heating body; coating: coating the surface of the dried pre-impregnated tire base with asphalt or immersing the pre-impregnated tire base into the asphalt so as to enable the surface of the pre-impregnated tire base to be covered with the asphalt, then performing rough pressing by using a high-speed rolling heating body, and then performing fine pressing by using a low-speed rolling heating body. A preimpregnation-drying-coating combined mode is adopted,and the preimpregnation technology, the drying technology, the coating technology, the preimpregnation device, the drying device and the coating device are improved, so that preimpregnation, drying and coating are more adaptive, and the improvement of the quality of a waterproof coiled material finished product is promoted.

Description

technical field [0001] The invention relates to the technical field of asphalt waterproof coiled material production equipment, and more specifically, to a process and system for dipping asphalt. Background technique [0002] Asphalt waterproofing membrane refers to a roll material made of asphalt material, tire material and anti-adhesive material spread on the surface, also known as linoleum, which is often used for pasting waterproof layers. Bitumen waterproofing membranes include tire membranes and tireless membranes. Any roll-shaped material made of thick paper or glass cloth, asbestos cloth, cotton and linen fabrics and other tire materials impregnated with petroleum asphalt is called tire-shaped roll material; asbestos, rubber powder, etc. are mixed into the asphalt material, and after rolling The resulting roll material is called a rolled roll, that is, a tireless roll. [0003] Modified asphalt waterproofing membrane is commonly known as modified asphalt linoleum, ...
