Embodiment Construction

[0032] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings and specific embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0033] A batching method of self-adhesive waterproof roll material provided by the invention comprises the following steps,

[0034] S1, add 30-35 parts of No. 90 bitumen and 20-25 parts of No. 200 bitumen into the batching device;

[0035] S2, add 2-10 parts of SBS 1301, 2-6 parts of granular SBR;

[0036] S3, heat up to 155-165°C, dissolve for 0.5-1.5h;

[0037] S4, stir and mix for 0.5-1.5h, grind once, and the ground rubber is the masterbatch;

[0038] S5, add 1-3 parts of petroleum...

Abstract

The invention relates to the technical field of waterproof coiled material production, and discloses a self-adhesion waterproof coiled material batching method and a batching device.The self-adhesion waterproof coiled material batching method comprises the following steps: adding 30-35 parts of 90 # asphalt and 20-25 parts of 200 # asphalt into the batching device; adding 2 to 10 parts of SBS (styrene butadiene styrene) 1301 and 2 to 6 parts of granular SBR; raising the temperature to 155 to 165 DEG C, and dissolving the components for 0.5 to 1.5 hours; uniformly stirring and mixing the mixture for 0.5 to 1.5 hours, and grinding the mixture once, so as to obtain rubber master batch; and adding 1-3 parts of petroleum resin and 28-35 parts of talcum powder, stirring the components at 165 DEG C for 1 hour, and discharging a final product. The modifier SBR used in the batching method provided by the invention is granular, the granular SBR has no many limitations on temperature and blanking speed, and the granular SBR can be directly used for feeding, so that the batching method has the following advantages: a, the whole temperature rise process can be omitted, and thus a plurality of process control points are omitted; b, caking is avoided; c, mesh screening and oil immersion pretreatment are not needed, so that the feeding procedure can be simplified; therefore, by using the granular SBR, the overall feeding speed can be increased, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of production of waterproof rolls, in particular to a batching method and a batching device for self-adhesive waterproof rolls. Background technique [0002] Self-adhesive waterproof membrane is a material that can be adhered to the plane of the building for building waterproofing. It is generally rolled up for transportation and sales. The production of self-adhesive waterproof membrane generally includes two steps: batching and molding. Asphalt is used in the batching step, and the asphalt is modified by adding modifiers in the asphalt to improve or enhance the performance of the asphalt. Styrene-butadiene rubber (SBR) is a commonly used modifier. It is based on butadiene and Polymer elastomer material made by polymerization of two monomers of styrene. The whole process is to put SBR into a batching device with heating function (12m 3 , can be prepared with 10 tons of material), and then the mixing mechan...
