Problems solved by technology

However, the Shore hardness of the refrigerator door seal made of this kind of material is relatively large, and the Shore hardness is often greater than 70A. The surface roughness of the cover will become larger, and the refrigerator user will feel scratchy when touching the door seal with his hands, and the hand touch feeling is poor. At the same time, when this type of door seal is installed on the refrigerator door, the resistance is high , when the refrigerator door is actually closed and used, the phenomenon of the refrigerator door body clamping the door seal often occurs, which seriously affects the actual performance requirements of the refrigerator door seal

preparation example Construction

[0017] Adopt above-mentioned a kind of preparation method that feels smooth and delicate PVC door seal material, its specific steps are:

[0018] Step 1: Weighing: Accurately weigh each component according to the range of parts in claim 1;

[0019] Step 2: Mix the powder: Use a high-speed mixing pot to fully mix the accurately weighed PVC resin, hand feeling agent, elastomer, stabilizer, lubricant and antibacterial and antifungal agent. After mixing slowly for 1 to 2 minutes, mix according to the right Requirements 1 The plasticizer after the weight ratio is accurately weighed is all put into the barrel of the high-speed mixing pot and slowly added into the high-speed mixing pot to increase the temperature of the high-speed mixing pot. When the temperature of the high-speed mixing pot rises When the temperature reaches 100°C, all the plasticizer in the high-speed mixing pot is added into the high-speed mixing pot. When the temperature of the high-speed mixing pot rises to 105°...

Embodiment 1

[0023] In the present invention, the refrigerator door seal material is accurately weighed according to the following material parts:

[0024] PVC resin is 100 parts, plasticizer is 50-75 parts, filler is 40-110 parts, hand feeling agent is 1-3 parts, elastomer is 5-20 parts, stabilizer is 1-5 parts, lubricant is 0.2 to 1 part, antibacterial and antifungal agent is 0.2 to 2 parts,

[0025]

[0026] Mix the accurately weighed PVC resin, hand feeling agent, elastomer, stabilizer, lubricant and antibacterial and antifungal agent in a high-speed mixing pot. After mixing slowly for 1 to 2 minutes, accurately weigh the Put all the plasticizers in the high-speed mixing pot into the high-speed mixing pot and slowly add the high-speed mixing pot to increase the temperature of the high-speed mixing pot. When the temperature of the high-speed mixing pot rises to 100 ° C, the high-speed mixing pot All the plasticizer in the barrel is added to the high-speed mixing pot. When the temper...

Embodiment 2

[0034] In the present invention, the refrigerator door seal material is accurately weighed according to the following material parts:

[0035]

[0036]

[0037] Mix the accurately weighed PVC resin, hand feeling agent, elastomer, stabilizer, lubricant and antibacterial and antifungal agent in a high-speed mixing pot for 1-3 minutes. Put the plasticizers accurately weighed in the above weight proportions into the barrel of the high-speed mixing pot and slowly add them into the high-speed mixing pot to increase the temperature of the high-speed mixing pot. When the temperature of the high-speed mixing pot rises to 100 At ℃, all the plasticizer in the high-speed mixing pot barrel is added into the high-speed mixing pot. When the temperature of the high-speed mixing pot rises to 105°C, the filler is added through the high-speed mixing pot barrel, and the high-speed mixing The pot continues to mix and the temperature continues to rise. When the temperature of the high-speed m...

Abstract

The invention discloses a smooth and delicate PVC door sealing material and a preparation method thereof. The smooth and delicate PVC door sealing material is composed of PVC resin, plasticizer, filler, feeling agent, elastomer, stabilizer, lubricant and antibacterial mildew preventive. The preparation method for the smooth and delicate PVC door sealing material includes the steps of weighing; powder mixing; mixing; extrusion forming and hot cutting. According to the smooth and delicate PVC door sealing material and the preparation method thereof, the problem that an existing soft PVC materialincreasingly cannot meet the requirements of the market for the surface softness and fine texture of the product is solved. A polar group in the feeling agent and a PVC material system generate an attachment point by H bond bonding, a smooth main chain in the feeling agent is attached to the surface of the PVC material to form a smooth and continuous film, a convex-concave phenomenon of the product surface is improved, the surface roughness and surface defects are reduced, the smoothness and softness are improved, the smooth and delicate texture degree of the product surface can be improved lastingly, and the smooth and delicate PVC door sealing material is suitable as a low temperature flexible refrigerator door sealing material.

Description

technical field [0001] The invention relates to the field of a refrigerator door seal material and a preparation method, in particular to a smooth and delicate PVC door seal material and a preparation method. Background technique [0002] Most of the door seals used in refrigerators on the market are made of ordinary polyvinyl chloride (PVC for short) as the base material and some additives. However, the Shore hardness of the refrigerator door seal made of this kind of material is relatively large, and the Shore hardness is often greater than 70A. The surface roughness of the cover will become larger, and the refrigerator user will feel scratchy when touching the door seal with his hands, and the hand touch feeling is poor. At the same time, when this type of door seal is installed on the refrigerator door, the resistance is high , When the refrigerator door is actually closed and used, the phenomenon of the refrigerator door body clamping the door seal often occurs, which ...
