Description

Produce the equipment of using tackiness agent for the color-painted steel strip flocking of oceanographic engineering

Technical field

The utility model relates to a kind of equipment of steel plate flocking with tackiness agent of producing, and is specially the equipment of using tackiness agent for the color-painted steel strip flocking of oceanographic engineering of producing.

Background technology

The flocking steel plate is a kind of high performance material of implementing static flocking continuously and make on the starting material coiled material.The flocking steel plate, as a kind of comparatively novel implanted article, has unique excellent performance.The flocking steel plate is made substrate with color-painted steel strip, any decorative pattern of wanting on villous surface can also be planted.Produce this flocking color-painted steel strip, tackiness agent is had to many requirements: at first, adhesive therefor must have remarkable base plate bonding power, and can as the bonding mode of porous plastics and glass fibre propping material, not peel off; The second, require tackiness agent can meet wearing quality and the long-term safety of flocking color-painted steel strip; The 3rd, the flocking color-painted steel strip needs to stand the multiple process operations such as rolling forming processing, punch process, spiral processing, plasma cutting, seam is folding in the course of processing, and this just requires tackiness agent that good snappiness can be arranged.In addition, for meeting the life-time service of flocking color-painted steel strip production and construction, tackiness agent need have certain fungicidal properties and package stability, and meets the environmental requirement of modern society.

Because the flocking color-painted steel strip is type material, domestic market does not have professional production to use the equipment of tackiness agent for the color-painted steel strip flocking of oceanographic engineering now, in ocean environment, rainy, the high temperature of atmosphere, high wind stream and concentration of saline fog are high, commercially available Flock Adhesive, be used on the color-painted steel strip static flocking of oceanographic engineering solidity to corrosion, erosion wear resistance, humidity resistance, binding strength, water resistance and antioxidant property not good.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned weak point, thereby the equipment with tackiness agent for the color-painted steel strip flocking of oceanographic engineering of producing is provided, the tackiness agent of its production meet shelf-stable, bonding firmly, Anti-erosion, anti-oxidant, wet-heat resisting and the over-all properties such as processing characteristics is good.

The technical solution of the utility model is: produce the equipment of using tackiness agent for the color-painted steel strip flocking of oceanographic engineering, comprise autoclave, high-speed stirring still, hybrid reaction tank, low speed stirring kettle, it is characterized in that: described autoclave be linked in sequence high-speed stirring still, hybrid reaction tank, low speed stirring kettle.

Compared with the prior art the utility model has the following advantages: the product that the utility model is produced, there is the shelf lives long, and the normal temperature sealed storage phase is more than 1 year; Cohesive strength is high, and color-painted steel strip and terylene fine hair are all had to high-intensity cohesive force; Water resistance is good, and in the ocean environment of the rainy and high wind of atmosphere stream, long-term use properties is stable; Snappiness is moderate, when guaranteeing flocking color-painted steel strip Joint strength, can meet various processing requests again; Solidity to corrosion is good, at concentration of saline fog, in high ocean environment, in long-term the use, can protect color-painted steel strip not to be corroded, and can guarantee lasting cohesive strength and antioxidant property again.

The accompanying drawing explanation

Fig. 1 is device structure schematic diagram of the present utility model.

In figure, 1. autoclave, 2. high-speed stirring still, 3. hybrid reaction tank, 4. low speed stirring kettle.

Embodiment:

Below in conjunction with accompanying drawing, the utility model is further described.
