specific Embodiment approach 1

[0012] Embodiment 1: The smooth putty of this embodiment is composed of main ash and curing agent. The weight ratio of main ash and curing agent is 100:2, wherein the main ash is composed of the following components according to the weight ratio: Unsaturated polyester resin: 100, Accelerator: 3~5, Styrene: 3~5, Pigment: 4~6, Ultrafine talcum powder: 70~90; The curing agent is composed of the following components according to the weight ratio: Initiator : 100, Pigment: 2~4, Filler: 4~6. The unsaturated polyester resin is an air-drying unsaturated polyester resin; the accelerator is cobalt isooctanoate and N,N-methylaniline; the initiator is cyclohexanone peroxide and methyl ethyl ketone peroxide; the pigment in the main body ash It is nano-titanium dioxide; the pigment in the curing agent is yellow pigment paste, and the filler is fumed silica.

specific Embodiment approach 2

[0013] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the main body ash is composed of the following components according to the weight ratio: air-drying unsaturated polyester resin: 100, cobalt isooctanoate and dimethylaniline: 2~ 4. Styrene: 8~10, nano-titanium dioxide: 5, superfine talc powder 1800 # : 50, superfine talcum powder 1200 # : 20, superfine talcum powder 800 # : 10; The curing agent is composed of the following components according to the weight ratio: cyclohexanone peroxide and methyl ethyl ketone peroxide: 100, yellow pigment paste: 3, fumed silicon dioxide: 5.

specific Embodiment approach 3

[0014] Embodiment 3: The smooth putty of this embodiment is composed of main ash and curing agent. The weight ratio of main ash and curing agent is 100:2. The specific ratio is shown in Table 1.

Abstract

Disclosed is sliding atom ash, relating to a kind of polymeric putty. According to the shortage of insufficient fineness and smooth after coating and polishing of the current, the invention provides the sliding atom ash with high fineness and smooth, which comprises main body ash and firming agent with the proportion of 100:2 in mass, and the main body ash comprising the following components with the proportion in mass to be: unsaturated polyester resin, 100; accelerant, 3~5; phenylethene,3~5; pigment, 4~6; ultra-fine talcum powder, 70~90; the firming agent comprising the following components with the proportion in mass to be: initiating agent, 100; pigment, 2~4; stuffing, 4~6. The product possesses the following advantages compared with current adhesive power with the metal, fine and smooth putty surface, replenishing the opening and crack more than 5mm for one time, small degree of shrinkage, fast drying speed, heat-proof temperature being í 120 DEG C, possessing a certain degree of tarnish proofness, good air seasoning property, convenient polishing, and mating with various oil paint.

Description

Technical field: [0001] The invention relates to a polymer putty. Background technique: [0002] Atomic ash is a kind of filling material, its scientific name is polymeric putty, it is mainly used for caulking and filling on the surface of metal and non-metal materials before painting, so as to obtain a flat and smooth appearance. Atomic putty is mainly made of unsaturated polyester. It is different from other existing synthetic resin putties in that it can adjust the curing speed with a curing agent and can be cured quickly. Its largest application market is currently mainly for automobile manufacturing and overhaul industry. With the continuous development of the domestic automobile industry, the types and output of automobiles are increasing, the competition among industries is becoming increasingly fierce, the appearance quality is becoming more and more eye-catching, and the quality requirements for putty are getting higher and higher. There are more and more varietie...
