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.

Example Embodiment

[0017] Using the above-mentioned preparation method of smooth and delicate PVC door seal material, the specific steps are as follows:

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

[0019] Step 2: Mixing powder: Use a high-speed mixing pot to fully mix the accurately weighed PVC resin, hand-feeling agent, elastomer, stabilizer, lubricant, and antibacterial and anti-fungal agent. After mixing slowly for 1min to 2min, it will follow the rights All the plasticizers that are accurately weighed in the weight ratio in 1 are put into the barrel of the high-speed mixing pot and slowly added to 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℃, all the plasticizers in the high-speed mixing pot barrel are added to the high-speed mixing pot. When the temperature of the high-speed mixing pot rises to 105℃, the fill...

Example Embodiment

[0022] Example one:

[0023] The refrigerator door seal material of the present invention 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 0.2~1 part, 0.2~2 part of antibacterial and antifungal agent,

[0025]

[0026] Mix the accurately weighed PVC resin, hand-feeling agent, elastomer, stabilizer, lubricant and anti-bacterial and anti-fungal agent in a high-speed mixing pot. After mixing slowly for 1 to 2 minutes, the weight ratio will be accurately weighed. Put all the plasticizers in the high-speed mixing pot barrel slowly 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 reaches 100℃, the high-speed mixing pot The plasticizer in the barrel is all added to the high-speed mixing pot. When the temper...

Example Embodiment

[0033] Embodiment two:

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

[0035]

[0036]

[0037] Mix accurately weighed PVC resin, feel agent, elastomer, stabilizer, lubricant and antibacterial and antifungal agent in a high-speed mixing pot. The mixing time is 1min~3min. After the mixture is fully mixed, it will be The plasticizer with the above weight ratio accurately weighed is 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 to 100 When the temperature is ℃, all the plasticizers in the barrel of the high-speed mixing pot are added to the high-speed mixing pot. When the temperature of the high-speed mixing pot rises to 105°C, the filler is added through the barrel of the high-speed mixing pot to mix at high speed. The mixing pot con...

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 ...
