Problems solved by technology

However, the production of ordinary linoleum base fabrics in China generally has low production capacity, high energy consumption, slightly poor product performance uniformity, general lipophilic effect, and unsatisfactory oil impregnation performance, which leads to problems in the subsequent production of coils. The uniformity of coil oil immersion is slightly poor, and the production efficiency is low.

Embodiment 1

[0030] This embodiment provides a production method of oleophilic linoleum base cloth, the production method comprises: polyester chips are transported to the silo, crystallized and dried, screw extruded, melt filtered, spinning, cooling, drafting, pendulum Wire laying, needle punching reinforcement, hot rolling and chemical glue impregnation drying and winding packaging; wherein, based on the total weight of the glue solution, the glue solution used for the chemical glue impregnation and drying includes: acrylate 6wt% , water 93wt% and curing agent 1wt%; Specifically as follows:

[0031] Using polyester chips as raw material, the undried amorphous polyester chips are sent to the high-level silo by the air pulse conveying device, and fed into the crystallization and dryer through the rotary valve; the crystallization temperature is controlled at 165°C, and the drying temperature is 170°C; after crystallization and drying, the moisture content of the slices is controlled to a c...

Embodiment 2

[0033] The difference between this embodiment and Example 1 is: based on the total weight of the glue solution, the glue solution used for dipping and drying the chemical glue includes: acrylate 7.5wt%, water 91.5wt% and 1wt%; other processes and Parameters are all the same as in Example 1.

Embodiment 3

[0035] The difference between this embodiment and Example 1 is: based on the total weight of the glue solution, the glue solution used for dipping and drying the chemical glue includes: acrylate 8wt%, water 91wt% and 1wt%; Same as Example 1.

Abstract

The invention discloses a lipophilic felt base cloth and a production method thereof. The production method comprises the following steps: successively carrying out crystallization and drying, screw extruding, melt filtering, spinning, cooling, drafting, wire placement and net pavement, needling reinforcement, hot rolling and chemical glue dipping and drying on polyester chips. Based on the totalweight of a glue solution, the glue solution for chemical glue dipping and drying comprises 6-8wt% of acrylate, 90-93wt% of water and 1-2wt% of a curing agent. The invention provides a production method of the brand-new lipophilic felt base cloth. According to the production method of the brand-new lipophilic felt base cloth, an acrylate solution which contains the curing agent is selected to be used as the glue solution to prepare the lipophilic felt base cloth, thus, the prepared lipophilic felt base cloth has good oil immersion property, and the problems that in a follow-up coiled materialproduction process, oil immersion uniformity of a coiled material is slightly poor, and the production efficiency is low are solved.

Description

technical field [0001] The invention belongs to the field of polyester filament linoleum base cloth, and more specifically relates to an oleophilic linoleum base cloth and a production method thereof. Background technique [0002] Polyester linoleum base cloth is a kind of non-woven fabric, which can also be called: (tire base cloth, linoleum base cloth, waterproof base cloth). Polyester linoleum base fabric is a kind of non-woven fabric product processed by 100% polyester staple fiber through carding, acupuncture reinforcement, dipping and shaping. 900m-1650m, thickness 0.6-1.4g. It is the main base of the popular waterproof membrane (SBS, APP coating). Polyester felt base fabric (tire base fabric, polyester felt, polyester tire) has high strength, high elongation and puncture resistance, light weight, high tensile strength, good permeability, high temperature resistance, freezing resistance, aging resistance, characteristics of corrosion. [0003] At present, the produ...
