Embodiment 1

[0026] A production process of a hot-melt waterproof coiled material, comprising the steps of:

[0027] Step 1: Raw material preparation: The raw materials are recorded by the number of parts: 100 parts of asphalt, 1 part of softener, 40 parts of thermoplastic polyurethane, 7 parts of thickener, 1 part of defoamer, and 16 parts of filler; the asphalt is 10# petroleum asphalt One or more of 70# petroleum asphalt and 90# petroleum asphalt; the softener is the second-line oil reduction or the third-line oil reduction; the thickener is one or more of sodium-based bentonite, organic bentonite, and diatomaceous earth The defoaming agent is methyl silicone oil or polysiloxane; the filler is calcium powder or stone powder; the softener is an auxiliary agent used to improve the processing performance and use performance of rubber, which can increase the plasticity of the rubber material and reduce the rubber The viscosity of the material and the temperature during mixing can improve th...

Embodiment 2

[0033] The production process of embodiment 2 is substantially equal to that of embodiment 1, and the difference is that the raw materials are recorded by the number of parts: 110 parts of asphalt, 3 parts of softening agent, 50 parts of thermoplastic polyurethane, 11 parts of thickener, 2 parts of defoamer, filling 21 doses.

Embodiment 3

[0035] The production process of embodiment 3 is substantially equal to that of embodiment 1, and the difference is that the raw materials are recorded according to the number of parts: 120 parts of asphalt, 6 parts of softening agent, 60 parts of thermoplastic polyurethane, 15 parts of thickener, 3 parts of defoamer, filling 26 doses.

Abstract

The invention discloses a production technology of a hot-melt waterproof roll. The production technology includes the steps of raw material preparation, mixing, discharging, dip-coating, attaching, cooling and rolling. The production technology has the advantages that tensile strength and aging resistance are improved, foam generation is inhibited, and the produced waterproof roll is smoother in thickness.

Description

technical field [0001] The invention belongs to the technical field of production of waterproof coiled materials, and in particular relates to a production process of hot-melt waterproof coiled materials. Background technique [0002] The waterproof material products made by impregnating asphalt or polymer waterproof materials on the carcass are provided in the form of rolls and are called waterproof rolls. [0003] There are following deficiencies in the production and preparation of existing waterproof coiled materials: [0004] 1. Insufficient in tensile strength; [0005] 2. The problem of uneven thickness. Contents of the invention [0006] The purpose of the present invention is to provide a production process of hot-melt waterproof coiled material, so as to solve the problems of insufficient tensile strength and uneven thickness in the production and preparation of the existing waterproof coiled material proposed in the above-mentioned background technology.
