Problems solved by technology

If the above slurry and process parameters are selected improperly, although the heat insulation performance can be guaranteed, the reflective degree of the finished product is still weak, the softness is poor, and the powder on the surface will fall off because the finished product has not passed through the calendering process.

Embodiment 1

[0011] Take 20kg of aluminum paste with a solid content of 70%, 8kg of aluminum powder and 72kg of acrylic resin and mix them evenly to make a slurry for sizing. Acrylic resin is a mixture of 50% ethyl acrylate and 50% butyl acrylate;

[0012] Take the non-woven fabric as the base material, and put the non-woven fabric base material into the sizing car for sizing and drying to make semi-finished products. The speed of the sizing car is 20 / min, and the drying temperature is 110°C;

[0013] The above-mentioned semi-finished products are put into a calendering car to be calendered to be finished products. The speed of the calendering car is 30 / min, the calendering temperature is 85°C, and the calendering pressure is 40T.

Embodiment 2

[0015] Take 30kg of aluminum paste with a solid content of 65%, 3kg of aluminum powder and 67kg of acrylic resin and mix them evenly to make a slurry for sizing, wherein the acrylic resin is formed by mixing 45% butyl acrylate and 55% ethyl acrylate;

[0016] Take the non-woven fabric as the base material, and put the non-woven fabric base material into the sizing car for sizing and drying to make semi-finished products. The speed of the sizing car is 25 / min, and the drying temperature is 90°C;

[0017] The above-mentioned semi-finished products are put into a calendering car to be calendered to be finished products. The speed of the calendering car is 35 / min, the calendering temperature is 75°C, and the calendering pressure is 30T.

Embodiment 3

[0019] Take 25kg of aluminum paste with a solid content of 75%, 5kg of aluminum powder and 70kg of acrylic resin and mix them uniformly to make a slurry for sizing, wherein the acrylic resin is formed by mixing 55% butyl acrylate and 45% ethyl acrylate;

[0020] Take the non-woven fabric as the base material, and put the non-woven fabric base material into the sizing car for sizing and drying to make semi-finished products. The speed of the sizing car is 23 / min, and the drying temperature is 100°C;

[0021] The above-mentioned semi-finished products are put into a calendering car to be calendered to be finished products. The speed of the calendering car is 33 / min, the calendering temperature is 80°C, and the calendering pressure is 35T.

Abstract

The invention designs a kind of vehicle cap with the heat insulation reflection supatex fabric preparation method, it is by the supatex fabric took the base material, enters the supatex fabric base material the starching vehicle starching, prepares dries, is entering rolls over the lathe finishing calendering to become the end product, the pulp which general uses is with 20~30% aluminum thick liquid, 3~8% aluminite powder and 60~80% acrylicresin mix becomes; The starching vehicle vehicle speed is 20~35 / min, prepares dries the temperature is 75~85deg.C, calendering the pressure is 20~40T. The invention heat insulation effect good, counter- luminosity strong, flexibility good, the superficial caking is reliable.

Description

Technical field: [0001] The present invention relates to a nonwoven fabric. In particular, it relates to a non-woven fabric with heat-insulating and light-reflecting functions. It is mainly used to make car roof covers. It belongs to the technical field of nonwoven fabrics. Background technique: [0002] Traditional materials used to make car roof covers include plastic cloth or ordinary aluminum-coated non-woven fabrics. The roof cover made of plastic cloth has poor heat insulation performance and weak light reflection. The roof cover made of aluminum-coated non-woven fabric is made by putting the non-woven fabric base material into the aluminum paste on the sizing car, and preparing for drying to make the finished product. Since non-woven fabrics are not heat-resistant and aluminum is heat-resistant, how to combine the two becomes the key point, which mainly depends on the size on it, the speed of the sizing vehicle and the selection of the drying temperature. If the ...
