Abstract

The embodiment of the invention discloses a continuous and automatic production line of a polyurethane adhesive and aims to solve the problem that since the materials are in contact with air, crust is generated and influence is caused on the product quality in the intermittent production process of the existing polyurethane adhesive. The continuous and automatic production line of the polyurethane adhesive comprises a calcium powder bale breaker, a calcium powder drying tank, a calcium powder cooling storehouse and a calcium powder measuring tank which are successively connected with one another via a pipeline; a carbon black powder bale breaker, a carbon black powder drying tank, a carbon black powder cooling storehouse and a carbon black powder measuring tank are successively connected with one another via the pipeline; a side feeder, a pre-mixing screw machine, a first-stage screw machine, a high-viscosity material cooler, a second-stage screw machine, a material pressing machine, a filter and a split charging device are connected with one another via the pipeline; the outlets of a prepolymer measuring tank, the calcium powder measuring tank and the carbon black powder measuring tank are communicated with the inlet of the side feeder via the pipeline; the outlet of a catalyst measuring tank is communicated with the inlet of the second-stage screw machine via the pipeline.

Description

technical field [0001] The invention relates to the field of polyurethane adhesive production, in particular to a continuous automatic production line and a production method of the polyurethane adhesive. Background technique [0002] Polyurethane adhesive is used as an adhesive. Widely used in construction, machinery, automobile, packaging, textile, printing and daily necessities and other fields. At present, the domestic production method of polyurethane adhesive is to use an oven to heat and dry carbon black, calcium carbonate and kaolin powder; use a high-speed disperser or a power mixer to mix the liquid material (prepolymer and other materials) with powder ( Carbon black, calcium carbonate, kaolin and other materials) are dispersed, ground, mixed, and then added with catalytic aids, vacuumed to remove air bubbles. Due to the intermittent production, when the material tank is transported, it will contact the air to produce skin, which affects the product quality, low ...
